ha. i hear ya. when i was 16 i had multiple amps and four subs as well. so i know where you're coming from. what i didn't know back then was that i needed an electrical system to support my equipment. you're lucky enough to have forums like this where you can get advice, see build pictures, etc. back in the 90's my only references were magazines, local shops, and friends who didn't know jack. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
i have 3 amps currently. but only one is for subs. two are for my front speakers. i have literally spent dozens of hours wiring the amps, perfecting routing. see my build log for some ideas on how to wire multiple amps and not have it look like a spider's den. wire management is important. work on proper wiring methods now and it'll help you throughout.
take pics along the way, of every step. pics keep you honest. if you are embarrassed to show something, fix it. detailed pics of my builds was one of the best things i've done and it's helped me be a much better installer.
