I am having trouble deciding between 2 12'' infinity kapa subs and 2 12'' alpine type rs. Both are duel voice coil. The Ininity Kapa 120.3 DVC are $120 each on ikesound.com and the alpine swr-241d are $115 each.

Please let me know which subs you think I should get.

Also, would it be ok to run them off a Profile Clarus 1200 AMP?

 

I would say to go with the type r's. If it were between Kappa perfects and type r's I would go with infinity. But out of those two, go with the type r's. What are you going to power them with?

I am thinking of powering them with a Profile Clarus 1200 Amp which runs at 300watts x 2 RMS

 

I dont know if you have not looked at the JBL 600.1 but it pushes around 700watts and is aonly $195. The profile looks good and probably performs pretty good too but I have heard nothing but good things about the JBLs. My buddy has a 97 GMC ext cab with 2 alpine type r 10s and he is going to be pushing them with a JBL1200.1 next week. I will let you know how good it sounds. Right now he is pushing them with an alpine MRD 500.

I thought they were only 1 channel amps?

Also, my friend has a Clarus 800 pushing his 2 10" Polk Dx subs in his probe gt andd they sound great.

 

It is a one channel, but that doesnt meen that you can only run one sub off of it.

 

What would I have to do to run it to 2 subs? I bought My 91 GTA 350 with the wiring already installed. Its 8 gauge phoniex gold amp kit with everything i need already in the hatch. Im builinding a custom box for the hatch next week.

 

The only thing you do is hook up all the wires to the power output. I am not sure if you want to keep the 8 ga wire though. You might want to upgrade to 4 ga. And since you are looking at getting DVC subs there are a couple of options on how to wire them. I will try and find a good page for you to check out.

Brian

 

Thanks. Im still debating whether to go with The profile amp or the JBL. Also, the alpine type rs on ikesound.com are 4 ohm woofers. Will that make a hige impact with either amp? Im not looking for competition grade sound, just alot of bass for my music while im crusing.

Im also going to upgrade my head unit to A Pioneer Premier DEH-740 MP.

My current setup is a Sony Xplod 52x4 head uint with remote (A nice unit, but i want the pioneer screen for looks) , and 2 Soundstream Tarantula 6x9 150 Watt RMS Speakers. Im eventaully gona install custom kick panels and 6.5 inch component speakers, due to the fact my 4x6 rockford front speakers are blown.

 

If you are getting dual 4ohm speakers, you will either have a 4 ohm load(series) or a 1 ohm load(parallel) If the profile amp is not 1 ohm stable then it will shut off if you hook up the speakers at 1 ohm. But it is a 2 channel 2 ohm amp so you could use that one. In general you will get more power the lower the ohms just based on basic laws of resistance. Here is the page I was telling you about.

There all kinds of things to look for and every amp and sub changes the game. It is kind of a pain, but it will pay off in the long run.

My friends dad is an electrical engineer, so I guess I'll ask him about that. I think im going to go with the Clarus 1200 amps since it runs a t 300 watts x2 at 4ohms. Im going to order them this week, by the tyime they come in my box should be nearly finished. Ill let you know how it goes and post some pics of the finished setup.
One more thing, do the infinity kappas run a 2ohms unlike the alpine type rs?

 

http://www.infinitysystems.com/carau...er=KAP&Cat=SUB

 

why are you not choosing the jbl amp? its better, period.

 

the clarus will send 450Wx2 @ 2ohms...

 

yet, for roughly the same price (bp1200.1) you get just under 1600 watts into 1-or 2-ohms...

 

not roughly the same price but $70 more, and about $200 more worth of power. JBL is the way to go. And it is like half the size.

Brian

 

I checked the specs and the jbl 1200 runs at only 600w x 1 at 4 ohms. If i split it into 2 channels, i would only ebe running 300 per speaker which is the same as the clarus?

 

no. you can't "split" a mono amp into two channels. what you do is wire the two subs onto one channel. what this does it halves (or doubles, depending on how you wire it) the impedance of the speakers. for example, if you have 2 4-ohm subs, you wire them together in parallel and you now have a 2-ohm load. now, the jbl is rated at 1200x1 into 2 ohms; fortunately for us, it is very underrated and actually puts out something like 1470 watts--pretty damn good for less than 300 bucks. so, you hook up both speakers to the amp, and they each get half of that--roughly 750 watts a piece. not at all bad, considering the price.

 

If i do this , will 750 watts per sub be too much for the infiniti kappa 12 subs? I would get the perfects. but my spending limit is $500.00

 

have you thought about getting a single sub, like the adire brahma? check it out here

 

i wanted to go with 2 12,s becuase im building a duel 12 custom enclosure. I have pretty much settled on 2 Infinity Kappa 12s dvc unless someone can recomend better subs around 125 each.

 

Tonights burning question must be, the jbl 600 or the jbl 1200 amp for 2 12inch infinti kjappa subs , (oir should i use 2 12"4ohm dvc type rs) Can i run both brands of subs at 2 ohms?

 

I would go with the type r's. I think that you will get a good amount more thump out of them and they are really clean too. I would also go with the JBL 1200.1 just because that way you have room to grow. You can always turn down the gain on it and only push so many watts, the 600 can only go so high.

Brian

 

First thing, you cannot get 2 ohms with dual 4 ohm dvc subs. You can however get 2 ohms, if you run each sub from it's own amp. Therefore, I'd recommend 2 JBL 600's. As for the subs, it all depends on what you really want from the system. If you want serious spl numbers, go with the Alpine. As for overpowering the subs, don't be as concerned with that. It all depends on how high you run the gain, bassboost, and bass. If you run a conservative amount of each, you'll be fine. I'd also suggest getting a small sub crossover. You can get some for as low as 20 bucks.

 

jbl amps run stable down to 1 ohm. you can wire both those subs fine to any bp series jbl amp without a problem. or, you could pick up the 4-ohm SVC versions, since it will play marginally better at 2 ohms than at 1 ohm. and you dont need a crossover--its built in to the amp. buying 2 600.1s is stupid in this instance

 

agreed. If you have 2 dual 4ohm voice coils you can run them @4ohm or @1ohm. The JBL is 1ohm stable. I dont see the problem. I am not sure what ohm voice coils the infinities have though.

Brian

 

Thats why I dont want to buy the alpines. Im pretty sure that the infinities run at 2ohms.

 

There is nothing wrong with running @ 1ohm. The only time you might see a problem is if you have everything at full volume/gain/bass boost for 24hrs a day everyday. Then it might be a problem.
But if you dont want to do it, its your call. If you are wanting to spend around $125 on a 12 then check out these Kicker L5 12" woofers. They will kill both the type r's and the kappa's.

get the alpine. they rock and are almost indestructable. dont buy a profile amp. i did and had to return it 3 times. kept breaking because they are crap. dont waste your money on them.

 

Don't limit yourself to those two choices.

An Adire Shiva costs the same as those, and I think it's a higher quality driver. I haven't had the chance to audition one yet, but those subs typically get compared to MUCH more expensive, sound-quality oriented stuff like the JL W6s, etc. There are a lot of small speaker companies out there that are making fantastic stuff, but aren't as well known because they don't **** millions into advertising.

the jbl amp's are awesome and you can get earbleeding bass out of the 600.1 but i think the 1200.1 would be better.

 

The reason I recommend getting 2 of the 600's, is that it will be much more of a reliable set up, if you run it at 2 ohms instead of 1. Running at 4 ohms would be ideal, but getting enough power at 4 ohms is hard. And the reason I mention the extra crossover, is because it allows you to have further control over the level the subs play at. I run one before the amp on my system. It really is just helpful in allowing you to fine tune the sub portion of the setup.

 

Will the JBL 1200.1 Amp msupply too much power to the infinity Kappa 12"subs? Would the 600.1 be a better choice? Also, whould I need a capacitor?

 

I dont think you need a capacitor. The JBL 1200.1 will be too much, if the gain is all the way up. Just turn down the gain, bass boost, and bass and you will be fine. Then if you want it really loud turn some of them up a bit.

Brian

 

I would buy the 600.1 , but if i have to run it at 4 ohms, i will only be getting 150 watts per channel

 

with my experience with Infinity i think without a doubt they are the best subs anyone can buy be it kappa refference or perfect.
