I don't think a PC power supply is enough to power my sub.



The amp I have right now is 800 highy underrated watts.

I would think that you'd want at least a 15 AMP supply.
Dude those are expensive!



Is there something cheaper?!



I mean, I can get a decent plate amp for like $180, and that PS is $159!

this should work too:

13.5V output @ 12.5 amps. $74.95



Or you could just take a car battery, and set it on the floor by the amp. Then hook the batt to a charger and viola! Power supply! (No don't do that.. lead-acid batteries have a tendancy to release hydrogen when you charge them. See Hindenberg)

I have a friend who did that, but he hooked it all up through his home entertainment system too on top of his computer.

That sounds pretty good, I think I'm going to do that...

If you have an old computer, its power supply will do. You only need 12 consistent volts to power the amp. Spice the wires on the power supply so you have a constent and a remote, then plug in the power supply.

Which wires though, I mean, there's like 8000.

ITs nto hard, look on the intraweb to find which wires are 12v. Might even say in a power supply manual or on the PS itself.

I shoulda listened to rfreeman27, he was right all along! https://www.nopistons.com/forums/pub...1047683358.gif



Okay so I need 12V..shouldn't be too hard, I have one of those connected to a P166, LOL. https://www.nopistons.com/forums/pub...>/bigthumb.gif
