It should be fine long as the amps to subs ohms are correct

I have a dub audio 2502 amp, do i use 4 or 8 gauge wiring ?


Despite the fact that they claim that the amplifier is 500 watt RMS if you look at the fuse it has on it, which should be one 30Amp fuse it means that the max that you might get out of this amplifier is 300 watt RMS. So an 8 Gauge cable will be more than enough for it. However, saying that, using a 4 gauge cable will not harm it in any way. what you should check before buying a 4 gauge cable is if it will actually fit in the allocated 12V terminal.

Amplifier For Powering Sony Xplod xs-l121p5


Pump the brakes!
You need to know the RMS power rating of the sub you are powering.
Dont exceed the RMS power rating of the sub by more than 25%.
If you see a peak power rating on either the sub or the amp, ignor it, means nothing. Always compare RMS ratings.
Example: a Sony 12" Xplod sub, boasting 1200 watts, will only handle, 350 watts RMS, so the amp you choose to power the sub should be 350 watts RMS as well, and should not exceed more than 25% of the RMS power handling (487.5 watts).
Bottom line, know your RMS numbers, not Peak.

Infinity 1211a @ 2 Ohms


Hello monkey_flea, Your subs will share the amp output. And if you are not careful, you'll end up blowing them. The amp puts out 1300 watts RMS at 2ohms, the subs have an RMS power range of from 75-350 watts, and you'll be driving them with 650 watts each. A better power match would be to series the subs to present an 8ohm final load. This will reduce the output power to a level the subs can handle. Or you could buy 2 more 12.1's and connect them series-parallel for a 4ohm load and each sub would still be getting 325 watts RMS, just about the maximum they are rated to handle. Hope this helps.

Rockford fostgate p500-2 amp overheating pls help!


Your Amplifier:
125W x 2 @ 4-Ohms RMS
250W x 2 @ 2-Ohms RMS
500W x 1 @ 4-Ohms bridged RMS

Your Subwoofers = Dual 4 ohm
Possible wiring configurations of (2) Dual 4 ohm voicecoil subwoofers are:

2 ohm Stereo
1 ohm mono
4 ohm mono


That amplifier is not 1 ohm mono stable.

You need to put a 4 ohm load on the "bridged" terminals of the amplifier

Your best wiring configuration is going to be Series-parallel.

CLICK HERE to see the pic Larger

4721108.jpg You can also get the same result (power) by having the subs wired in parallel independently. Put both + on one sub to one + on the amplifier and both - on one sub to the - of the same channel of the amplifier.
Repeat for channel 2.
This will be a 2 ohm stereo load.
You should only use this method if the subwoofers are in seperate enclosures... not one big cavity.

Is it enough to power to 12 volge=ahagen 12oowatss dual 4 ohms


your Volfenhag 12" subs are rated at 1200 watts they are only 600 watts rms and the Rockford punch p4004 is only 200 watts rms so the answer is yes it will work but if you get a amplifier that pushes out 500 - 600 watts rms you will love the sound from subs
there is nothing wrong with the Rockford amp it just wont pound out the bass as hard but the good news is you will never blow the subs with it
when buying amps or subs make sure to look at rms rating that is the true power they actually have ie. (sub box says 1200 watt you think powerful but if you divide it in 1/2 you actually get 600 watts rms) don't get me wrong that's a nice rating. for a sub but you will want to match that number with the amps rms rating or lower. The RMS is what makes the car pound the higher the RMS the better
hope this helps

Adjusting wattage on kenwood kac 9103 class D mono amp


That amplifier is 900W x 1 @ 2ohms.
If your subs are 4ohm SVC wired Parallel, resulting in a 2 ohm load, each sub will only see 1/2 of the rated power. (450W ea.)
Your gain (sensitivity) setting should be between 75% and 85% to max. You will be fine.
