what brand sub do you have because alot of manufacturers *cough*sony like to give their ratings in a very shady manor like 1600watts* and in the most discreet part of the instruction books it says *at 1/2 an ohm, but the amp is only stable at 4ohm or higher

i love the idiots who wire them at 1/2 ohms .. and sometimes when they say 1600watts it usually is PEAK power so you gotta watch it

When you are looking to match subs and amps, you at least need an amp that can power the sub's rms power. So if you have a sub that is 500 rms and 1000 max at 4 ohms, you need an amp that can at least push out 500 watts at 4 ohms. If the amp runs at 2 ohms, then 500 watts at 2 ohms would be more than enough power for that sub. ...i think.. lol

Lol I'd like to see someone wire a Best Buy amp at .5 ohms. I run my amps at .5 each but they are pure beasts :).

Anyways look for RMS power not max. It is also known as nominal power. Match that, dual 4 sub you wire to 2 ohms and a dual 2 you wire to 1 or 4 so figure it out n match.

Ok here is the two 12' pioneers i have that a friend gave me after he got his 15's and there brand new...

So heres my question i know how to hook them up and the amp itself but im not sure what amp i need and im not sure about the whole ohms thing and how u hook them up with the different ohms and which one they need to be hooked up at so all the help i can get is appreciated...

Also i wanna stay with pioneer cause everything i have is pioner so can someone show me which pionner amp will work best with these and how to hook it up with the right ohms for the best sound quality??? Thanx

An amp that will put out 300rms at 2 ohm will be good enough for you. That is all you will need for those pioneer subs. Just about any amp out there will do that for you.

And 96vtech, you don't need an amp that powers a subs RMS power. It is more of a maximum amount of power you should throw at a sub, not a minimum. There is nothing wrong with giving a sub less than its rms rating. The worst thing that can happen is you will lose some output. Which is much better than blowing the subs voice coil.

If you are choosing between those two amps, go with the first one. You can wire them to a final load of 2 ohms together, or 4 ohms individually. But not to 2 ohms individually.

Ok for the first one then how do i wire it @2ohms together???

Umm you can't wire 2 4 ohms subs to 2ohms :fyi: It's either a final load of 4 or 1.

They are single VC subs ;)

You would be correct if they were Dual 4 ohm voice coils, but two single 4 ohm voice coils can be wired to a final load of 8 ohms of 2 ohms. So in his case he would wire to a final load of 2 ohms.
