    was thinking of using some of my new/old car audio components that ive had for years sittn in the basement for a amp rack and speaker modding project. i could use some help regarding an amp rack and speaker cabnets , also how and or what kind of inverter would you need for the amps ? pictures and design ideas would be most helpful here , thanks.....oh almost forgot it would have 2 or 3 amps depending on configuration,1 pair of front speakers and sub w/enclosure.

    no way... i want that infinity component set.

    you could put a computer in that sub box pretty easily.

    i'll definately help you with this project

    ya the component set is very nice and new btw, i had a set and sent them back to crutchfield before the warrenty expiried and i never reinstalled them, the woofers are still in plastic bags that are sealed along w/ the sub( fresh !) i took very good care of the amps also so i want to make a sweet amp rack, the amps have a powered sliding door to show the blue light power triangle and cooling fan that will match my case very nicely:rockout:

    the only problem i see with this idea is you'd probably want to magnetically shield the speakers to keep the pc components safe.

    depending on the wattage of the amps you'd need one hell of an inverter. if you're electronically inclined you could probably build a power source for the 14.4v lines for the amps.

    you could also just use a deep cell car battery and a battery charger then source the 12v off of that.
    coldarkstare says thanks.

    A simple computer PSU will work according to the size of the amp, trust me, I use a 400W PSU with 28A on the rails with a 240W Coustic amp to a 10" sub and all ya have to do is jump the green wire with a ground(black) on the 20/24 pin connector and use a yellow wire and a black wire to the B+ annd jump the B+ wire to the remote and ground to ground and power up and thump!

    yes... BUT, for larger amps that wont work.

    my 2000watt lighting audio will blow even a pc power and cooling 1200watt computer psu with the amount of power it draws.

    i wouldn't recommend using a PC psu for car audio amps.

    indeed , the sub amp is a 401f mono channel that can push 350 or so rms and 1200/1400 w/max i believe , the 2 501f are 4 channel amps that are 50 w/x 4 or bridged at 2 channels 150w and the infinity speakers can handle that no problem(planned on that when i got the equipment :)) so ill need to get the math down on paper and really plan this out , this will depend on the cost of the inverter really, hell if its within budget ill put a nice cap inline with it for good measure.

    I'Ve been using them for years on my amps and I used the same 400W on my old Legacy 1200W and is hit just fine without really any drop in volts/amps
    And in house speakers dont really need alot of juice to pound. My 10" hits just as hard in my house as my 12" in my car

    Heres of my homemade cable. Easy really, its a female molex connector from an old dead fan. You could get the wire a bit bigger in gauge but this is suffice for my applications.

    No problem man! I use this with the 240W amp up to a 1000W JVC sub and the 400W PSU powering it. I cant turn it all the way up or it blow me outta my chair lol. I also made a cable out of a headphone jack and 2 RCA cables to hook up the amp to my computer for awesome bass in my games.

    Yea safer is better but I just did a cheap way out and sounds good too with no noise in the sub. Buying a $120+ battery with a $150+ PSU is way outta my range for a low wattage amp. It really just depends on the size of the amp.
