Frequently Asked Question:

1 got 3 different amp’s to choose from which is best for my 2 dvc 4ohm subs,and how do i wire it 4 more boom?

i have two 4ohm dvc PERFORMANCE TEKNIQUE sub 500 rms,and three amps to choose from but dont know wich is the best for my subs could you let me know which of them you think ill get more power from and how to wire that subs to that amp? here are the specs..—————PERFORMANCE TEKNIQUE SUBWOOFER CBM-5712

Answer by mrwakeup
All three of those amps are NOT enuff to power TWO of your subs.

you have two subs that are 500rms EACH with 1000watt PEAK…

Based off 500 each=needing 1000watts RMS to both….AT minimum to hit RMS.

So assuming you want to get full potential, none of the amps listed will do that.

The first amp:
Power Output
RMS Power at 4 Ohms125 W x 2
RMS Power at 2 Ohms175 W x 2

so 175*2=350

2nd amp:
400W x 4CH (1600W) @ 2OHM MAXIMUM
165W x 4CH (@ 2OHM) LESS THAN 0.5% THD
110W x 4CH (@4OHM) LESS THAN 0.3% THD

this is a 4 channel amp. And might (I SAY MIGHTTTTT) be able to give you the MOST power out of all of the others….but you are looking at 400w a channel. so using two channels of the 4 would grant you 800 watts….

And the last amp:
Continuous Power :
125W x 2 @ 4 ohm
190W x 2 @ 2 ohm
380W x 1 @ 4 ohm bridged

380 watt…RMS….at 4 ohm Bridged….

Not enuff for two 500watt rms (1000watts total) subs.

And realize these subs can/will peak at 1000 per sub as well…so in essence take up to 2000 watts at times…(burps…) but not all the time…
I would look at getting a mono amp that will handle 1000watt RMS.
That is my suggestion.
