I'd still like what ever circuit you give me, if any, to run off of my 12V car battery since I plan to make it so that when these circuits turn on, my 300W amp will turn on, since currently it's using a toggle switch. But if I need a different power supply, that's fine, I'll just add something to do the job.
And if you're wondering why I have a 300W amp, with 2, 300W subs, hooked up to a car battery, which is connected to a 2A smart trickle charger, it's because they cost me $40 and I had no other place to put them.
