Well, I finally got my Type-R *hurray for me!!*It is the 1241 model, 4 ohm, DVC, 300 RMS, 1000 peak. But when I went to wire it parellel, my amp keeps giving me an overcurrent light. I'm sure I have it wired right, so is my amp not capable of running a DVC sub in parellel? My amp is a Sony 1507 or sumthin like that, check my sig for the model and numbers. I know it being a sony is what everyone is gonna say is my problem, but I don't have the money to get a different amp right now, so I have to do the best I can with this one. I attached a quickly drawn pic to show how I wired it, can someone tell me if it is right, if there is a better way of doing it, or if I just need to get a new amp before running this sub, cuz right now my Xplod sub is sounded way f*ckin better than the Type-R Thanx for any help.

I doubt your Sony can handle a 2 ohm bridged load. You'll have to run the coils in series making an 8 ohm load. Or get the 2 ohm coil sub and series the coils to 4 ohms.

AJ_92RS

You mean run them in series to get an 8 ohm load.

I knew what you meant. But I doubt he did.

To run them in series you need to go from the + of the amp to the + of one coil... well here.. the dots marks are wires. OK?

Amp+ ...... +one coil- ...... +other coil- ...... -Amp

OR you could just use one coil for each channel of the amp.

Right output+ .... +one coil- .... -right output

Left output+ .... +other coil- .... -left output

OR you could just run one coil of the sub. Just because you have 2 coils doesn't mean you have to use both of them. You would actually get more power to the one coil if you ran it bridged off the amp.

Hope this looks OK. I'm on my damn WebTV and it don't have PictureMaker on it.

AJ

DISTURBthePEACE

would it sound better than my sony if I use one coil on the type-R bridged just like I have my sony or will the Type-R hit harder or not as hard or if I wire the Type-R in series will it get more power if I wire it bridged using one coil and will it hit harder in series or will I just have to experment? Also, what amp would you guys request to buy to run this bad boy to it's full potential? Thanx alot

DISTURBthePEACE

Here is what Crutchfield lists as the specs on the amp...

Key Features:

150 watts RMS x 2 at 4 ohms
380 watts x 1 in bridged mode
190 watts x 2 at 2 ohms

the second coil is really like a second sub so if I run off of each channel im only getting 150 watts into each coil or 190 if I can get them down to 2 ohm...can I bridge both channels? Can both coils on the Type-R recieve 300 watts RMS and 1000 peak or is that both coils combined meaning each coil can only get 150 RMS, 500 peak or what? IM SO CONFUSED!!!! F*CK F*CK F*C F*CK F*CK!!! Anybody got a good amp for sale/trade?!?!?!

First of all you have to run both coils or you will fry the sub.
Second wire the sub in mono. The specs you gave say it will work. Take your pos + of your amp and run it to both pos +'s on the sub and take your neg - of your amp and run it to both your neg -'s on the sub. This will give you a 2ohm load. This should give your sub more power. The way you have it wired now is giving you a 8ohm load and your not getting any power.

Justins86bird

Thanks for pointing that out. Fixed it now.


If your looking for an amp to run 2 ohm bridged, look for something that advertises 2 ohm bridge or 1 ohm stereo stable. Also, most class-D mono sub amps can handle a very low impedance load.

AJ_92RS

Where did you hear that? I've seen a guy run a set up like that for 5 yrs now and he ain't blown no sub.

No. His amp shows 190x2 into 2 ohms, not 190x1 into 2 ohms. No. The way you said to do it is the way his picture shows and that's what is making his amp overheat.

You hit 135.7 dB in a car stereo comp? What did you do, yell as loud as you could while you were in the truck?

Aj your a ****ING DUMB ***

I have 1 8" sub 1 what a dumb ****

Go look at the records on DBdragracing.com thats all I need to say!

AJ_92RS

It was a joke. Calm down. I didn't mean it that you "only" hit 135.7 dB. I meant it as kind of a hidden compliment because you did it by only using 1 8".

I've hit 135.5 dB with my set up I have in my car, with the exception of the sub. The sub I had at the time was a crappy *** 12" 8ohm MTX Thunder 3000. I had 2 the night before, but while I was testing it, I popped one. Kinda glad I did though, 'cause the Pioneer souds MUCH better. I was surprised. Plus the Pioneer is a 4 ohm.

Oh... One more thing.... I am not a f*ucking dumbass!!!!!! I'm just a regular dumbass!!! And that's

MISTER DUMBASS

Woh woh woh, calm down you 2. Nobody has answered my most recent questions yet. Can anyone help me? pleaze?

What it sounds like your saying is do this....and I don't think it works that way.

DISTURBthePEACE

Or do you mean this? I still don't think my amp will run this way.

Terry Kennedy

The first pic is what I was talking about, it will give you your bridged mono 2ohm load. The way I read your spec's your amp should be able to handle it. IF not then you need to get a new amp or you will have very little power as you do now. My 8 is a dvc sub so I know what I'm talking about. If you want a new amp I'm going to a 10 so I have my 8 and 2 dx 350's for sale. The amp is stable to 2ohm mono and does 417 watts at 2ohm. I'll let you have one of the amps for $150 + shipping.

As for you AJ I'm sorry I blew up, I kinda took it a little to seirous.

If you all still don't belive me ask polecat he used to be my boss when I worked for kicker. I'm sure he'll tell you the same though.

AJ_92RS

Wiring Wizard

G-O-D Damn I hope that link works, and helps you understand what I'm saying.

What Terry is telling you is correct on wiring it in parallel, but if your amp can't handle it, it can't handle it. My buddy has the EXACT same amp you do with 2 10" 4 ohm Sony subs running off of it. He tried running them parallel off the amp in bridged mode, and his amp did the same exact thing yours did. Plus he blew a fuse.

So now he has each channel running each sub. Right channel (or channel 1) to one sub and Left channel (or channel 2) to the other sub.

You basically have "2 subs". Just run each voice coil off of each channel seperately and your amp will be fine. You don't "have" to bridge your amp to have a good sounding system, or a lot of bass.

Good luck ,
AJ

AJ_92RS

COOL!!! The link worked!!!

OK. Now you can either wire it up like I just told you (in stereo) or use Option #2 in that link. That's it. That's the only 2 options you have.

From what I understood, Option #1 is the way you have it wired now, right? That's what keeps making your amp hot and go into protection mode. It's too little of a load on the amp (2 ohms bridged).

I sure hope this helps you. My fingers are tired. It's SO hard to explain this stuff in words. It's SO much easier in person.

AJ

DISTURBthePEACE

I finally said f*ck it and bridged my amp to one coil....380x1 RMS so the specs say. DAMN that think hits like that, and I still have an entire coil to use!! I LOVE it . I actually prolly have a coil and a 1/4 since the Sony don't push what it says prolly. I would love to buy your amp, but I don't have any money, unless your willing to trade amps straight up, sorry. Thanx for the offer though . I already brought out the cop once today playing with it making it sound perfect, hahaha . Thanx for all the help! I will get pics when I get them developed.

AJ_92RS

Isn't that what I told you to do the first time?

AJ

DISTURBthePEACE

yes, yes it is, I just wanted more dammit! LOL I shoulda listened to you.....:hail:AJ_92RS

Cuno

DO NOT DO THAT!!! You WILL fry your sub.

Do not do this either, unless you only have a subwoofer output running to your amplifier! If you are running both left and right channel signals to your amplifier, then on to your sub, you will cause your voice coils to push against each other which is not something to be desired. This will cause major damage to your subwoofer!

mcss383

short the other coil. If you don't do that then the T/S parameters of the driver will change, meaning a change in box size and such. Short the unused coil (run a wire from the + to the - of the coil) and all is well.

AJ_92RS

Where do you people come up with this stuff?

That's not true at all, UNLESS you don't have them in phase with each other. THEN you'll screw 'em up.

Dual voice coil subs were made EXACTLY for that reason. Running off of 2 channels at the same time. They came out WAY before amps were "bridgable". Personally, I think they're old technology. Kinda like Isobaric setups. They were both crutchs when there was no other alternative.

AJ

AJ_92RS

Now that, to me, sounds somewhat reasonable. Only "somewhat" because I don't know why you would need to do this, or IE, what does this do (theoretically)? I mean obviously it's going to make it just one big continuous winding of wire, but how does it help/change things?

AJ

spartyon

i have my type rs wired like this + to - on the sub itself and then the other + to the +on the amp and the other - to the - on the amp. is this right cuz i noticed today when i opened the hatch that it didnt sound right and a buddy of mine said it sounded like the voice coil was goin bad or something like that. do i have mine wired right?

Justins86bird

Hopfully this will shed some light on the topic of powering a single coil

I have been doing custom and competition installs for over ten years now. I am pretty sure I know what I am talking about.
If you only run one of the coils, the chance that heat will rise to an unexceptable level is almost a gaurantee. The magnetic field inside the coils will work against each other as opposed to the way that are suppose to and you will casue your voice coils to melt.

Cuno

Follow Justin's link. Enough said.

It expains the enclosure property part that he mentioned above.

It's about time someone agreed with me!! Thanks you. Hope you don't trash that new sub. I tryed to warn you.

DISTURBthePEACE

Ok, that article said not to do it cuz it will mess with some paramaters, but it didn't say anything about melting the coils. Right now I'm not worried about messing with my paramaters unless it permanetely changes them and when I get a different amp they will stay like they are now. I am once again confused, someone tell me whats what. Oh ya, while I'm at it, one of my buddies has a punch amp, the one that does 200x2 or somethin like that...would this work better? If so I'll see if I can get it off of him.

AJ_92RS

Boy. I bet you never thought this could be so confusing, or that you bought such a retard sub.

That's one reason I've never bought/used/installed dual voice coil subs. There's too much "Yes, if...." and "No, but...." It's almost as bad as designing a ported box.

I guess I'm a firm believer in K.I.S.S.

The "low freq., mono" thing makes sense if you run each coil seperately. But I've had home speakers that I never worried about that with, and never had a problem. Guess I was lucky.

The Thielle/Small parameters makes sense also, but I still don't see how this would "BLOW" the sub easier. Maybe each coil isn't as "large" in a DVC, so it doesn't disipate heat as well? I don't know.

Just take the f*cker back and hook your Sony back up. J/K At least you didn't have to worry about all the "if"s, "and"s, or "butt"s!!! LMAO

AJ

DISTURBthePEACE

I fyed it. Blew the sh*t out of it comin home from classes this morning. When I pulled it out of the box smoke just POURED out of the box. I just stood back and said to myself "that can't be good....." Thank *** four warrantys. I'm gonna keep the sony sub till I can get an amp to run the Alpine with.

KlayBuRn

Looks like im a little late, but when i ran my DVC channel for channel ( Fosgate 800.4 and a 15' POWER DVC), it wasnt pretty...

I didnt destroy anything, but didnt sound right, the coils where fighting each other, and i pulled the plug before anything bad happened...

DISTURBthePEACE

I took my sub back and the guy said he had never even thought of running just one coil. I told him not to try it. I have, however, aquired a Rockford Fosgate 300.2 amp from a buddy. Traded him straight up my Sony for his Fosgate till I can get my own. We traded amps, and everything still sounds bout the same. His sounds the same and he still has a quarter of amp to turn up. I have his Fosgate on my Sony sub cranked all the way and its just a tad louder than my Xplod on 3/4 was. But hopefully the Fosgate will run the Alpine right. Anyone know if it will? Or will I have to try and see?

KlayBuRn

hahaha

Id take Fosgate over Sony ANYDAY, and twice on Sunday

Cuno

If the posts above did not help you, be sure to either run the voice coils in:

series

+ from amp to + of first coil, that same coils - to the + of the other coil, the second coils - to the amps -

parallel
+ from amp to + of first coil and to the + of second coil/- from amp to both - on the sub.

I used 2 RFPunch 500a2 amps to run my Alpine Type R subs. I was running 4 of them though. So I was only running tha amp at 2 ohms mono. I had 1 running at 1 ohm mono for awhile before it began to cut out.

You may want to consider either bridging one channel of the amp to 1 ohm, or if you have two sets of RCA cables on the back of your stereo, connecting eitehr both lefts or both rights to the amp instead of one each, then connect both voice coils to each channel of the amp because the signal will then be the same.

DISTURBthePEACE

So what your saying is run it like I did the first time when my Sony kept f*ckin up. Or do I only use one channel....ok, he're some more pics, pick the correct one ya'll!

DISTURBthePEACE

Or this....

Same thing if I go w/ the series wiring...both channels or 1 channel? sorry for being such a retard with this, I've never worked with DVC before...why can't alpine make a SVC?!?!?

mcss383

first one.

AJ_92RS

Hey Peace Disturber ...

Just for clarity, use two diff colors for your wires in your pics. I'd say the 1st one also if I could tell for sure what you are trying to draw.

The two wires in your pic are touching/crossed so it's impossible to tell how they are really running. OK?

BTW, I'm sorry you blew your sub. I feel partially responsible. Like I said earlier, I've never done that, nor my friend, but I guess we could've just been lucky, or we don't have ears as strong as yours.

AJ

mcss383

well its pretty obvious, one pic is a bridged setup, the other is just using one channel.

AJ_92RS

Well since I've been designated the "Dumb ***", I'm giving you the title of

Cuno

This is Parallel bridged mono.

Cuno

this is series bridged mono

Cuno

this is parallel 1 channel

Cuno

I recommend running the series bridged mono set-up. However, you can also run the parallel one channel set-up with the amps you have.

If you decide to buy a new amp, look into investing in one that is 1ohm stable mono. The specs may seem weak when you first glance at them. But realize, if the specs on the amp are:

75X2 @ 4ohms

this equals

150X2 @ 2ohms
300X2@ 1ohm
600X2@ .5ohms
or
600X1 @ 1ohm

AJ_92RS

Thanks Cuno for drawing that. I would have done something like that a long time ago (what.. 3 days now) but I can't do stuff like that on this webtv.

I'm in the middle of moving and my comp. is packed away in a box somewhere. This webtv ain't made for nothing technical like drawing pics, but it works well for looking at pics of these (o)(o) !!!! LOL

If he would have had these pics a while ago it would have saved him a lot of grief, some which I feel I caused. I guess I'll never be running a DVC sub off only one channel anymore. Thanks for setting me straight on that (and you to Terry).

AJ

mcss383

Mr. Smart *** thank you very much! LOL

DISTURBthePEACE

Don't worry bout it, thats what warrantys are for . I make GOOD use of my warranys, trust me . I fryed my amp 5 times, with about 3 month intervals. I had taken both the pre-amps on my reciever and used 2-to-1's (took the 2 reds and put them together and the 2 whites and put them together) on them and then ran my RCA's from that to the amp and apperantly your not supposed to do that.....but it did sound better than it does with just one pre-amp hooked up.

CUNO: thanx for redrawing those pics for me. Also, how do you figure those amp specs like that? just double the number as the ohms fall or what? I've never quite grasped the concept (I'm not good with numbers.)

Everyone else: Why didn't you tell me that you couldn't read my pics??!?!? LOL j/k Thanx for all the help everyone

Cuno

That is basically it. When the resistance is cut in half, since the voltage suppy is still the same, you pretty much just multiply your wattage by 2.
