wat AMP would you all prefer to be pushing 2 10" Kicker Comps ???

 

your only at 300 RMS, so i'd say. go kicker all around, go with a kicker KX series 350.2, or ZX series 250.2, they are both pretty cheap and are excellent amps, even a tad underrated.

 

If you can still find a Soundstream Van Gogh 400.2 I would ****** it up instantly. These are the last of the real Soundstreams and are supposed to be the best amps Soundstream ever produced. Other than that I would say Kicker is a safe bet as would the older Fosgate amplifiers (I have no experience with the newer Fosgate stuff, I hear mixed reviews). I would stay around 400 to 500rms, it's always good to have a little headroom on your amp, just be conservative with your gain and boost settings and you'll be fine.

 

jbl amps are good for the price also, kenwood is good but overrated, orion is good also, and so is viper. but just go with kicker!

 

just about anything over 500w will do you fine so long as you dont abuse the speakers. you want to have enough to make it hit, but you dont want to be able to blow your speakers to hell and back in 1 note. for example, i have 2 Treo 12's w/ a 2400w amp, but im only runnin about 1/3 power on the gain. the way its set, i can cruse around slammin, then turn around and go to a spl comp. and make it even louder bu using the other 2/3 of its power if i wanted. the big thing is dont over power your subs, they wont last, but dont underpower them either because it weakens the voice coil by overstressing it when it trys to hit. personally i think anything from 500w-1000w will do you just fine

 

Where'd you hear that/ do you have proof?

 

you fry the voice coil by making it clip, its true. if the amp tries to hard, its starts to clip, this happens when you have a low watt amp trying to power a high watt sub/subs. its very true. , car audio tech's actually recommend that you overpower your sub/subs a little rather than underpowering them!

 

That's not under power the driver, it's over driving the amp.

 

no, its underpowering the sub. underpowering something means you give it less power than recommended, so if you have a 1000 watt RMS sub, and you hook up a 200 watt RMS amp, thats underpowering the sub.

 

True, but damage occurs when the amp is being over-driven, pushing it into clipping.
I am not disagreeing with what you said, I'm just adding that over driving an amp and pushing it to clip the signal is what fries voice coils. A speaker can be safely underpowered, as long as the amp is not pushed into clipping.

 

thats exactly what i said bro. i said that when you make the amp clip, it fry's the coils.

 

Which in itself does not damage the sub. If it did, everybody would blow their sub if they didn't listen at full volume.

What damages a sub is OVERDRIVING an amp, which usually happens when you use an amp that's too small, which is where this whole "underpowering" nonsense came from.

 

^^^Exactly. Underpowering a sub will NOT damage it. You can give a 1000W RMS sub 200W from a 200W amp all day. It wouldn't be as loud, but it will not damage the sub. Take that 200W amp and crank the gains until you overdrive the amp, that's where you can run into problems. But realistically you could probably drive a 1000W RMS (and no not Sony RMS) sub a 200W square wave and have it take it, 800W square wave could be a problem.

Samantics....

 

umm... thats what i said. if you make an amp clip, it WILL hurt the sub. obviously if you have an amp hooked up to a big sub it wont hurt it, unless the amp keeps clipping, that WILL hurt the sub. thats what i said. so theres no need to disagree when you tell me the exact same thing i said. i said in 2 different posts that making an amp clip WILL hurt the sub. and thats what you just said.

 

Just don't underpower them then you won't ever clip out your amp, you'll bottom the subs before that ever occurs

 

This really shouldn't be this long.
Underpowering speakers will not damage them. Overpowering the them will. When you over drive an amp and it clips, you are them giving the speaker more power. Think about the difference between a sign wave and a square wave. If you think of the center of the wave as 0, you can see that the sign wave has a good bit of time that the coil has less then full power. The square wave affectively delivers full power ALL the time. Full power for the time above 0 and because no negative power here, just heat, full power the time under 0. This is what starts to happen to happen (exaggerated example) when the amp clips. The wave start to become square waves, and get closer to full power all the time.

evilmonkeyracin, sorry you're question got lost. One DPX1000.2 for me.
Are you looking for what amp you should run? If so what are you looking to spend?

 

i disagree. this wont be long. actually making the amp clip means its trying as hard as it can, therefore when it tries that hard, it obviously is not having enough power to power the sub. if the amp had to much power, the sub would of blew right after the amp clips, but its not, so the little amp is trying to hard, causing it to clip, and thats when you ruin your voice coils, therefore underpowering a sub CAN ruin your sub, because the amp clips.

 

i am using an Autotek amp.... its awesome, but i was just looking for something cheaper cause my brother wants 225 for it..

 

just make sure you overpower your subs a very littel bit, that way if you do it right, you wont ruin your subs do to your amp clipping, good luck!

 

yeah im runnin a sony amp pushing out 500w at 4 ohms RMS "supposedly" on my 15" L7..and im gonna be havin 1500w rms too it...havent had any problems!

 

just be careful, i know the L7's can take it though. so you dont gotta worry.

 

i think its already takin a ****...i know where i might of ****ed it up before..sounds like the coil is unwound but i cant smell anything

 

You can disagree, but that doesn't change the facts.
Power=Heat
Heat is the enemy here (there are other ways a driver can be damaged). The bobbin can be warped by heat, the insulation on the VC wire can bubble up and expand until it rubs the wall, or the VC wire could just open. Under powering would give the VC less heat. You can't really give them so little heat they get damage. Depending on you amp you may be giving the sub a vary little power even if the HU is muted. Overpowering them gives them too much heat. Thats what the problem is. It also takes time, less time for more power, a long for a little to much power. You've got thermal loss to the air and bobbin material and thermal inertia to a smaller extent.

You're confusing buying an amp that is to small with giving the sub to little power. You may end up giving the sub more power with the smaller amp. But giving to more power isn't underpowering it.
Yes, buy an amp that is bigger then you need. This isn't overpowering the sub if you don't get goofy with the gains. You may end up giving it less power and having it sound better.

 

 

Dude he's exactly right. You do realize what happens when you clip an amp don't you? Imagine this, you're jumping on a trampoline and you go so high you hit the ceiling, BUT instead of slamming into it and bouncing back down you stick to it until the signal comes back down then drop, this is what clipping is doing. You're basically taking an AC current and turning it into DC current when you clip the amplifier. A sub won't clip, it will bottom out; an amp will clip and when it's clipping the sub's going to get a ton of heat built up in it. When you buy a bigger amp you're basically taking that "ceiling" you were hitting in the trampoline and moving it up so you don't slam into and stick to it. BTW Jack2908 every single square solo baric I've seen has died in rather short order. They either unwound the voice coils, or split at the recesses in the cone, hopefully yours isn't doing this.

 

1991 camaro, your saying the exact thing i was. making an amp clip WILL ruin the sub. its a fact.

 

thats basically what NEEDAZ said.... iroc_man

 

I think what everyone is essentially saying is overdriving an amp causes clipping, which causes a build up of heat in the sub, in turn causing severe damage to the sub.

Sound good?

 

yea, but i was the first one to say it. and yes that sounds right sully.

 

ive got a legacy 2400w amp that i got brand new off ebay or like 180 w/ shipping. now we all know that a legacy amp is not going to push 2400w unless you find a good class "D". however it has been a great amp for me. i have 2 treo 12's and i run my amp at maby 1/3 power and it slams. mind you i say it slams, but i dont have a hatchback or any kinda small car w/ this system, it is in a cadillac that has some thick leather seats and a piece of sheet metal that seperates the passanger area from the trunk. im not using any sound deadner either. i have had several legacy amps in the past and didnt get rid of them because i blew them up or burnt them up, i got rid of them to get a bigger amp. i didnt paun them off on some little 16 or 17 year old kid either, i sold them to friends who still have them. ive had my legacy for about 3 years now, and it runs just as strong now as the day i got it. now you may not want a 2400w amp, but they do have other watt amps, ive seen them as low as 275x2 and as big as 1200x2. they have diffrent series of these too, i have the red series, i know they have a blue series and some others. just remember it doesnt matter mow big the amp is, you can always adjust the gain down so that you dont blow up your equipment. but anyway now that i have rambled a bit, my point is check out ebay. you can find some good deals on som new products.

 

 

i would try a 300 watt xplode. its what i used before i got my 800 fosgate for my P2's and they sounded better with the 300 but they dont hit as hard
