Thanks guys for the input.
Before this I was running my stereo from my in car computer but I have decided that I am going to sell that and before that I had a 9815 with a diamond D6 and D3 mono amp and was powering the CDTs with a alpine mrv t420.
I have done the big 3 and wired all things properly just need to find a good battery to power it all and I hope I dont have to step up to a h/o alternator.
