need help
 

i have an ultimate t3500d and it is not turning on all the fuses are fine im getting 11.8-12.4v with the car on acc on the power and remote the ground is right to the battery but it is still not turning on if anybody has anyideas that would be great

If you're getting 12v on the power cable and you've got 12v on the remote lead then double check your ground. If you're sure that your ground is good and the fuses in your amp are good then your amp is pooched.

Put the voltmeter right on the amps power terminals. Dont use the remote wire from the deck to try and turn it on, just connect the remote terminal on your amp directly to the + terminal on your amp. Make sure the voltmeter still reads 12v as you try to turn it on. If it drops really low then you probably have a bad ground or something. If it still doesnt turn on then there isnt anything to loose if you try to opening it up and see if you see anythign fried.
