Picking the right amp....

[war0827]

Will an alphine v12 Mono 1000watt amp be enough to power up two JL 10"W6 subs which are at 600 watt RMS for both?

[Hamsterman]

that should be cool- i am running a single kicker compvr 12- which is 400 rms max and my amp is an mtx thunder which i think is rated from 305 or 345 @ birth- i forget which- anyways i like having the amp a little less than the sub- so you can push it and not distort the sub as much/blow it

it all depends on if you run the correct set-up to have the right resistance for each sub into that amp- monoblock amps should be fine with 2 subs as long as u bridge them into into 2 or 1 ohm, or whatever is most stabel @ the highest wattage for that alpine- have any specs? anyone agree with me?

You got it backwards.

Not enough power is worst then to much power.

When you ask an amp to put out more power then it can produce, it clips. Basicly what happens is that it runs out of power.

i know that not enough power is bad- i guess i did contradict myself there- but the thing i meant to say is that the sub is rate 75-400 watts- and now that i think about it i do wish i had a 500 watt amp to power that sub- but the amp was a deal and i struck and i never really push that much power anyways, but 88 you are right

That amp should be enough to power the two subs as long as the subs are rated at 4 ohms each (and you hook it up in parallel).

Just to make it easier, here is a link with some specs

That setup will not work too well. The subwoofers only come in dual 4 ohm coils only. That means that each sub will have an effective resistance of 2 or 8 ohms each. If you just buy one of the subs, it would work well, but if you buy two subs, then the effective resistance will be either 1 or 4 ohms. This will not allow your amp to run at its full potential (1000 watts rms at 2 ohms)

[war0827]

so does that mean that i'll have to have 2 of those amps to run the 2 subs?

Damn, that changes the whole picture for me cause that means i gotta spend another $400 for another amp

Did you already buy the equipment? If not, you just have to choose a new amp to drive that sub.

[war0827]

well, i got a 1000watt alpine amp running right now, but i'm gonna change the subs i'm running right now with 2- 10" JL W3V2's. I wanna pick up 2- 10" JL W6's and add to what i'm going to have.

The W6 is different from the W6V2 also. The W6 has a contiuous watt usage of like 300 v.s. W6V2 which is like 400. Do you still think the 1000watt amp won't hold for the W6's?

If your amp isn't one ohm stable, which it doesn't appear to be... you have to run your speakers at 4ohm. At 4ohm your amp produces 500RMS which should be enough to push those speakers. You may want to look into different sub choices though. JL makes some good stuff, but they're not the only manufacturer out there that makes quality drivers.

[war0827]

well, just to make sure exactly what amp I need, i got some info/stats. Let me know which one i should get. Should i get 2 amps to power up both 10" JL W6 subs, or one amp?

JL 10" W6:
300W continuous power

Alpine MRV-T420:
2/1 channel amp
12V RMS continuous power 75wX2 @ 2ohms; 120wX2 bridged @4ohms; 240wX1 @ 4ohms
14.4V RMS continuous power 170wX2 @ 4ohms; 340wX1 @ 4ohms

Alpine MRD-M500 Mono:
900w max.
500wX 1 @ 2ohms (14.4V)

Alpine MRD-M1000 Mono
1800w max
1000wX 1 @ 2ohms (14.4V)

I think you already have a good amp why buy a new one and speakers? Pick out some new subs instead of the W6. None of the amps you suggested really work well for running two W6s. If you want two subs that run at dual 4 ohms you need a 1 ohm stable amp. Why are you so hardset on Alpine and JL? I don't believe Alpine makes 1ohm stable amps so you're shit out of luck in the Alpine department as far as powering those speakers. You need an amp that can produce roughly 600 watts at 4ohm if you want to go with Alpine (which you have the closest thing to it they make I believe).

Alpine is a really good company, especially with headunits and amps. Their amps are one of the cleanest on the market. Their speakers are so so, however they make a set of components that cost over 3 grand that was rated the best audiophile speaker by car audio magazine.

For the subs, you may wanna just get some JL W3's instead of the 6's. The W3's seem to have a lot more setup options/possibilities, coming in 2, 4 and 3 ohms. You could get three 6 ohm subs, or two 4 ohm subs. They should work good. Or for the price of the W6's, you may wanna look at some image dynamics idq's or the IDMax (only 320 online). You could also pick up some eclipse's or MTX 9500's.

thanks for all the help guys.

I stopped by an audio place around my house that did the setup on my car that i have now (they only did the labor, i bought the parts) and they told me that the W6V2 can either run 2 or 4 ohms and that all I would need is 1 Alpine M-1000 amp. They also said that the 2- JL W3V2's I have will run off my current amp (which is a Alpine M-500) @ 2 ohms.

Let me know what you guys think.
