So who here has got subs pounding in there trunk?

Use to, some crappy deal Best Buy set up and within like 2 months one of my subs and my amp had been blown.

But what does everyone else have? 

I already got some new subs.

Thats basically them except mine say on the box that they are "Dual 2 or 4 ohm subwoofer."

Thats the only real difference I could notice.  

Just working for this amp now

I got a question though, could I run both of my 12" subs with that amp at 2 ohms, to get like a total of 550 watts? 

Thats what I plan on doing, if I got everything right.

And whats the difference in ohms do really?

This is one of the more unusual posts to come through Gamespot. Well, I just happen to have been an MECP-certified car audio installer back in the day.

Based on your post, it's no wonder you blew your last amp (this is not an insult). The Punch series of amplifiers is Rockford's low-end or entry-level amp line, and if you had a similar entry-level amplifier before in any similar setup, it is not unusual for you to have blown the amp.

What happens is when you bridge a 2-channel amp into a single channel, the amp sees the load at half-resistance. So if you have an 8-ohm sub bridged to a 2-channel amp, the amp sees a 4 ohm load. Two 4-ohm subs hooked up to a 2-channel amp - presumably in parallel - will result in an effective 1-ohm load to the amp. A Punch amp, and even most high-end amps BTW, simply cannot handle a 1-ohm load, and blow up. Catch fire. Pop fuses. You get the picture.

I'm not sure what you have for subs, but I would reconsider your wiring setup. At the very least, purchase a dedicated mono subwoofer amplifier. Make sure the installer is MECP certified, or you get help from a Crutchfield tech.

There is nothing wrong with Rockford amps, they're great, just remember that entry-line amps will have a shorter life span and are more likely to crap-out on you

Myself? I've got a Pioneer Elite Head Unit running to three Alpine V-Series amplifiers, a single Alpine 12" SWR-1240D, two Kicker SS Series separates in the front, and two 4" coaxials for filler in the rear.

I also used to compete with a pair of Cerwin Vega 12" Subs, and another car had two Kicker XPL subs. 

Let me know if you have any more questions, I'd be happy to advise.

Oh, I thought you meant submissives.-Karayan-

No, a mono amp is an amplifier that only amplifies one channel. One amplifier can power multiple speakers when they are either bridge or in series (which changes the resistance, measured in ohms). I would suggest - based on the questions you are asking - that you visit this site. This should answer most of your basic questions, and if you have more, just ask me!Bozanimal

haha those are actually my old subs and thats my car.

I just noticed something.

My Rockford subs say they are P2 DVC.

Dual Voice Coil.

On that site you showed me it recommened that for subs with DVC's to use a 2- channel amp.

So would that be better than a Mono Amp?

Thanks again for all your help.

I have a truck. So, no trunk to put speakers in. Even if I did, I wouldn't see the point anyway. If you want to listen to your music loud, that's fine. Roll up your windows and turn the speakers up. But is it really necessary to force everyone in a five block radius to listen to your ****ing bass for 15 minutes? I can't possibly count the number of times I've woken up in the middle of the night because some **** is blasting his system as he rides slowly down a road two or three streets away at four in the morning.masterchief2512
