    Question Whats wrong

    Hey I have a pioneer DEH3500 head unit and a Rockford p5002 amp and two MTX road thunders and it all works fine except for the dimming lights. I recently bought a Lightning audio 1/2 farad cap, charged it, the battery is at 12.69 volts and i chargerd the cap to 12.58 volts. Now that it is installed correctly, sometimes the amp turns on and works like it should and others it doesnt turn on at all or turns on then off. The protect light does not turn on, on the amp, and i do have it wired right. So whats wrong does anyone have any wisdom for me? Help me out if you can, thanks.

    Does when it turn on and off to when it stays off have any correlation to when your car is running or how charged your battery is?

    With that amp it's probably 90% likely to be the ground. I used to see that problem alot installing stereos. The best practice is to ground the amp and the cap together and tightly using the bolts that hold down your car seats. If you can wiggle the cable at all you have a ground problem and it's guaranteed to give you spotty performance.

    Have you looked in the FAQ yet?
    How about the Wiki?

    What do you mean current always being drawn from your battery? If you have the amp turn on connected to your "acc" line or your power supply then the amps should turn off with your car and there should be no pull on the battery.

    Hey the grounds cant get much better. Do the cap and the amp need to be grounded seperatly or together? I have noticed that when i turn the outputs off at the head unit it will turn on and then i turn on the outputs and it will work just fine. So what is up?
