If you disconnect the speaker wires from the speaker output terminals of the amp, does the light still blink with the music?

Acoustic energy subwoofer makes noise on start-up but then won't play

The light on the rear of the sub indicates it is getting power so it is likely that the internal amp has failed, possibly due to age.

I recently change dc jack no power indicator computer lights for a minute then turn off

Remove the main battery and try again, next sub out the ram one at time testing as you go, sub another power supply if possible to be sure it is working correctly. If none of this helps, the motherboard is the next logical suspect.

The main problem I have having is I am getting power to my AMP but no power to the subs. I tested my AMP and subs in another car and everything worked so I know my hardware all works fine. I had someome...

okay , well you need to make sure all your conections are in the right spots, and that your IN LINE FUSE, between your amp and battery, the big glass one is not burnt, just take a look at the metal piece inside , if its a sold metal piece its good, if its burnt in half like a broken bridge it needs to be replaced. the next thing is the fuse on your amp, you need to make sure it is not burnt also. Check your remote that it is hooked up to the right wire. then check that your sub/speaker wires are connected properly and secure. YOUR GROUND WIRE IS HUGE HERE also. MAKE SURE IT IS GROUNDED TO A GOOD SPOT, YOU MAY HAVE TO MOVE IT AROUND A FEW TIMES TO FIND A GOOD GROUND!!!! if you check all of these things, it should work fine.. you can fiddle with your amp and bass settings levels. turn em up so when it works you know it, but not too much you dont wanna blow nothing :)

How can i test my rca output jacks with a test light? pioneer deh p3100ub. hooked up spkr, nothing. tried one rca plug to white(lt) and then red(rt). Unit has 4 rca jacks, 2 for subwfr and 2 for front...

:) the rca jacks have to be connected to an amplifier,, their signal is too lay to even light a bulb.. you have to connect it to a car amplifier and then from the amplifier to the speakers..

Just so you'd know,, once your deck plays and you hear music on your speakers through your normal speaker wires,, RCA jacks work..

Ok you have 4 jacks,, 2 subs and 2 front.. These should connect to a preamp,, which takes 4 inputs and allows you to equalize or adjust how the music should sound,, now from the pre-amp,, it runs to an amplifier,, thats powers the subs and another that powers the speakers.. Some amps have 4 inputs so you can use one amp for your subs mids and heights..

for example a basic music system is

1 cd player
1 pre amp
1 amplifier (4 inputs, 4 channel out)

you bridge 1+2 and connect this to 1 12" double coil sub woofer

the next 2 connect to 2 mid speakers example "rockford or ev 5 / 8 " and 2 tweeters for heights..

Thats a kicking tricked out basic car audio system,,,

Hope that helps you understand how it works..

My subs/amp are not working

when you car is running, it charges the battery somewhat. So the voltage problem is not a problem. The red light means the amp is going into ''Protect Mode". This usually happens when something is wrong with the amp. Usually the amp is getting hot. Check all of you connectiong and check the final impedance of the subs. Make sure the amp can handle the impedance of the subs. If you need anymore help, message me.

hi, your amp seems to be getting power but the cables might be wrong so it's not getting enough power. the light on the amp should be green if everything is going well. are you sure the cables are suitable for your amp?

No power output from the amplifier...

The EEE and protect leds being on is a clear indication this AMP is toast.

Subwoofer seem to be broke

The one sub that you described is gone, there should be no reistance at all when you push on them. It sounds like you got your gains set to high on that amp (maybe the amp is underated for your subs). When you turn up the gain to high your cause your amp to distort and it can get as bad as sending a pure DV current to the sub. That DV current will blow subs because of all the force directed in one direction. If you think about it the amp takes a DC current and turns it into a AC current which creates the frequecy (rate at which it alternates) that alternating current pushes and then pulls on the sub keeping it within its boundries.
