I've had a full audio system in my car for the past three years, including 1 two channel Power Acoustik amp that has recently stopped working. The power led is always green but I never have sound coming from my two 12's.
For about two weeks it would constantly stop thumping every now and then, I'm guessing when a braked or acelerated, every time there were G's. Well, it stopped working at a gas station, I turned around and hit the amp from fustration, and it worked! Only problem is that five minutes later it stopped working again and never again thumped!
I've swapped the RCA from my high's amp to the PS2-1200 and nothing.
My two amps both have common ground and power coming from a capacitor. I've also opened the amp, but haven't seen anything obiously wrong with it..

Re: No Sound From My Amp!
I am assuming the amp is not under warranty, if it is, rma it... if not, you have nothing to lose from trying this.
hitting it and having it work usually means something is loose or broken, remove the case and extract the circuit board.. clean all parts thoroughly using a good electronic or contact cleaner, i use crc qd electronic cleaner as it is cheap and available at most auto supply stores, just make sure whatever cleaner you use is not industrial duty and is plastic safe.
after the entire thing is cleaned (coils, caps, anything resembling dust), check with a magnifying glass for any broken solder joints, you can also very lightly touch components and see if they move.. this sounds like either broken solder joints, extremely dirty contacts, corrosion, or dry caps.. you can usually locate dry caps by looking for corrosion around the cap and discoloration on the top of the cap.
hope this helps, and hope you get it running; the ps2 amps are pretty nice when it comes to accurate sound reproduction. trin
I had the same with a power acoustik 2000 watt... power is coming on the green light and no sound. i took it to an electronics store to be repaired...... the guy told me this amp is a piece of **** throw it away.. and so i did... the problem was solved.. i now have a rockford fosgate 800 and it rocks 2 pioneer 12".

I'd not try that as the stock amp just won't have enough power at the sub .... Or will any cheapo wood box work fine? ..... I have an 03 ram 1500 QC with the infinity system...... I just purchased a new 2010 Dodge Ram Big Horn Crew Cab Long Box with the 6... 1 Power Acoustik ONV1-2000D and ONV4-1200Missing: lfa1

it can be used as a bass amp. if each pair of channels is bridged then you will basically have a 2 channel amp. just be sure to set the x-over's to lpf for subwoofers. I checked the power ratings, and bridged at a 4 ohm load will give you 250 rms watts per sub, so thats enough to run most 10's or 12's. there wasnt a rating for a 2 ohm load, but your amp should support it.
On your amp, there should be a switch (on the side probably) that has "LP", "HP", and "FULL" or "OFF". This is a switch for the low pass/high pass filter. Switch it to "LP" as this will allow only low frequencies to go to your subs, what you want. If you don't have that switch, go to an audio store or online audio supplier and get either a low pass filter, band pass filter, or a cross-over, and follow the wiring diagram that comes with it to filter out the high frequencies before they get to your subs.
