Thanks guys. I think I'm going to try the PC power source/battery combo. Won't be until Spring that I look more into it, but gives me time to plan it better. When I'm ready to get started 420Guy, I'll let you know.

 

No problem I will be here LOL. I will get my bro in law to keep his eyes open for a suitable power supply or 2 or 10 LOL. He comes across all kinds of crap from who knows where. He can probably put together 3 or 4 complete PCs from just the spare crap he has lying around. I watched him do it one day too, mine crapped out and needed a new motherboard. Was complaining about being without a comp for 2 weeks until I could afford a new board. So he put a temp one together with just crap he had laying around. Worked fine until I got mine fixed. Will let you know if I find anything interesting.

I keep a solar panel on an optima yellow top as my power supply in my cabin up north. You could also just use a 2amp trickle charger. Cranking it up pretty good I get a solid 3 hours of listening time. and the battery recharges the next day.

you can also shop on ebay for a CAE 40amp power supply. both setups will run you a little over $200, and you still a car head unit, an antenna, speakers...Just buy a entry level 2 channel receiver and build your own speaker enclosures.

 

there is lots of ways you can do it im only 16 and have a full car audio set up in my room my amp runs off a battery and my hu runs off computer power suply the yellow and red wire (aka acc) get put together and ground (-) stays by it self on your amp you put a wire from the (REM) to the (+) and leave the (-) by it self it is very simple if you have any qustions i will do my best to answer them i have many set ups in my room just let me no i would have to say with every thing i have just a lil over $500 buts thats hu mono block sub and box an speckers and power supply every thing is from a pawn shop lol peoples stolen lol

 

for your power supply find out what puts out witch rail on your ps puts out the most amps at 12v and thne cut the black and the red short and use the yellow and the black that are left your power supply wont turn on antill you bridge two wires on the big connetor that would usely plug into the mouther board of your computer
i will post a pic of it

 

this is what i mean it might be a bit con fuseing

 

this is for the amp

 

WARNING! By putting the red and yellow together you're sending 17v to the HU... I don't think HU are rated to run that high. Use only the yellow one, it will give you 12v, this will be enough for the HU and iy will not fry.

 

and this is what i ended up with !

 

After looking at your pics, i think your setup fine. At first i tought that you put together the yellow and red of the PSU... Sorry
