Go to any audio store and get you a 1 farad capacitor and you will not ever have this problem again. Or you could just take the power cord out of your amp every time you park and then re connect it. Although what you could do is mount a yellow top optima battery in your trunk with brackets so it won't move or nothing. Then run your power cords to your battery in the trunk then bam problem solved but at night I would reccomend disconnecting the battery cables in your trunk so it doesn't run down the battery. Oh btw I used to install competition Sound systems in cars for a living 4 years ago.
See i really dont think this is the correct way to wire an amp.
You need to have your supply running through a relay that is not always active.
Ignition circuit is normally used. That way when the car is turned off there is no capacity for the amp to draw any current as the relay is off.
I understand what your saying. Use a capacitor to keep some charge in the amp so when you turn it on there is not pop sort of noise.
But the key her is to take the amp off direct circuit.
Even an amp turned off will draw current if directly connected to the battery.
One in a circuit to the ignition will not.
