[QUOTE="Jasontb2000, post: 74671, member: 542188"] I'm sorry!! I had a brain fart. You can't fix this problem with a relay... BUT you can fix it with a diode and a capacitor, here's how.. Take a diode( a 1N4004) and place it in series with the amps turn on lead.(Striped side connects toward the amp) Then add a capacitor in parallel , the Pos. (+) side of the cap. connects to the striped (amp side) of the diode. the neg.(-) side of the cap. goes to ground. (not the ground of the amp but to the chassis. What this does is when you turn your radio off or power down the system, the cap. will cause the amp to have a delayed turn off. (As the cap. discharges the voltage to the amp turn on lead will drop slowly and not all at once.) You will have to play with it to get the right timed delay by changing capacitors. Usually you can use 220 - 1000uF caps. But besure to use a polarized electrolytic cap. 16V or higher. also the diode will keep the cap. from discharging any voltage in a reverse path to you headunit. But it will also cause a 0.7 voltage drop one your remote. I have never really seen any equipment damaged by a turn off thump, but I can't say that it won't! Good luck. [/QUOTE]
