You could try the positive lead to the relay box under the hood. Not sure what the amp draw of your amplifier is, but that should work OK.

Is there a fuse in the amp? Check that too. Also make sure your remote turn on lead is connected to a switched 12V source (like the radio fuse)and not a constant hot 12V source.

Use a voltmeter, and test the Main power cable at the am, and the remote turn on at the amp--both should read 12volts or so. If you have a volt meter with a continuance tester, test your ground at your amp as well.

Check and make sure your power wire isn't freyed and contacting the body. If the amp gets power through the ground it might react like you're saying.

Make sure that turn-on lead is on a switched 12V and not a constant hot too.

Check the ground, too. It sounds like the power isn't constant. Make sure you have a good chassis contact. I'd find an existing ground to test. The battery is the best place to hook up high drawing accessories, well... it's the safest. The wire leading the fuse box is rather small, IMO.

ok a friend of mine told me that all it was is. that we have a 20 min delay when we turn of our truck you can still lisin to the radio until you open the door or the 20 mins is up.so if you take the + of the battery and putt it back on you will not get power to the amp rate off. that is y after i left it alone for a little bit it was now on...dose this make cents :?:

I have my amp running off the + terminal on the battery. It then runs through a fuse, through the FM antenna grommet, and into the amp in the rear, which also has an internal fuse. My Kenwood deck also has a 12v remote turn on lead that tells the amp to come on when the deck does and to turn off accordingly. I would check that if you're still having problems.

No, this does not make sense. The only wires that are 'disconnected' after 20 minutes are those within the accessory panel within the underhood and sidedash fuse box... which include the radio among other things. Nothing can turn off the battery. If your head unit is lit, your amps should be working if your tapped into the battery.

Check the amp + and the amp - wire. Check the deck's remote + wire (the ground is the amp's - wire). Since it comes on and off, it maybe the amp. What kind of amp is it? My Alpine V12 had a fuse AND a circuit breaker. The breaker would trip if the ground was not consistent, the fuse went if the positive over-amperaged. That's why I think that ground should be checked. I couldn't find a decent ground point under the seats, but I wear very thick glasses :lol:
