Okay fellas, Some of you guys have been extremely helpful in broadening my car audio understanding, and I appreciate that very much, thank you. But as it seems it looks like my electrical setup is going cost more than I thought. My car audio stash is looking smaller the more I learn. To start off with should I go with the big 3 and a h.o. alt, or leave the stuff under the alone and get a 2nd battery in the back? Another thing, I was looking at a 12v 250 amp alt made by Delco for $170. Will this alt supply the power for 2500 rms. I plan on doing some other stuff with my electrical, but that could be in the not so near future. I made a deal with my wife that if I put this system in my truck she could get new flooring in the house. Yeah I'm about to be broke! Lol. Anyway what combination would work best for awhile...new alt, big 3, or stock alt 2nd battery, or stock alt with an adjustable voltage boast module, maybe a 12 to 16v converter somewhere in the mix. I'm working with $300. I just want to get a setup that will bang. I don't know enough yet to choose the best combo. There's so much information and I work 55hrs a week to support my family, little time, little pockets.
