If I have three subs, and two 2-channel amps and a stock electrical system, which am I better off doing?

Running both amps (both around 1100w RMS) at the same time, 2 subs on one, 1 sub on the other.

Or running all 3 subs off of one amp?

My only concern is that I won't be able to run 2200w RMS with a stock battery and alternator. Am I correct in thinking this?

And in that case, am I better running 1100w to 2 subs that are 500w RMS each, or running 1100w to 3 subs that are 500w RMS each?

Running 3 subs, they'd be slightly underpowered, but I'd have an extra sub. So, which would sound best?

 

how many ohms can you wire your amp down to? (1 or 2 ohms?)
are your subs dual ohm or single ohm?
your amp might heat up pretty quick if you run your subs down to an odd numbered ohm load that your amp might not be able to read. you might be better off running the two amps.. just to be safe.. i'm no expert on this stuff.. so i may be wrong. someone correct me if i'm wrong haha.. thats just what the installers told me..

I'm betting my amp can only handle 2 ohms when bridged. That's average, correct?

And if I wired the subs how crutchfield tells me to, it will be a 2.7 ohm load.

They are all dual 4ohm coils.

 

Yeah thats supposed to be average.. can you post a link to your amplifiers specs? i looked up "interfire 1100 rms" on google and it showed it was 1100 watts peak.. if it is 1100 peak i think you should go ahead and use two amps. just because that way all the subs will be at the same wattage and one won't be quieter than the other two..

 

I can never find it online either, but I called the manufacture. It's 2200 peak, 1100 rms. The other amp is a Pyle Chopper series, supposed to be "2x1200 rms", so I don't know if they mean 2400w rms or what. But, anyways, I'd rather stick to one amp, especially assuming the Pyle is at least 1200 rms. I doubt I could run 2400 rms, 1100 rms dims my headlights as it is, haha.

So, I guess my question now is, would 2 subs with full power be better than adding another sub and taking the power of each down?

 

i dont even know then man... can't find either of those amps on google...

 

PROVANTAGE: Pyle PL-A2220 Pyle 2-Channel 2400W Amp

Wow, disappointing. 2x250 rms at 2 ohms.

But, of course, that means my total RMS would be 1600. Would that be okay on a stock system? And then I'd have right around 500 to each sub.

 

No offence guys but this is like the blind leading the blind. Always post model # for the equipment in question. If you assume something be prepared to pay for it when the assumption turns out to be wrong. Get the model # of the interfire amp. Sub bass is going to be more about the box than it is the sub.

 

I would stick with one amp or the other, I would also run all the subs off one amp, unless they were the same amplifiers, but with running 3 subs, I would not run 2 off one amp and 1 off the other.

Just stick with one amp, and decide if you want to run 2 subs or 3, it's up to you.
