car amplifier to wall outlet

Yeah, jacob, can you just hook up all three power supplies to the batt bank?

If I did it that way, I would go 1 power supply with a huge *** diode on the + line going to each battery, then parallel the batteries for a strong 12. I don't know if the diode per power supply +12v line is necessary, but I would hate to have one power supply accidentally back feed another.

Im curious about that power supply and using it by itself for HT. What size wire does the outputs allow?

Do people not read any of the stickies anymore? //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif

I don't think they read at all.

to the OP, if you wanna use a computer power supply it takes some modding. I made a 12v supply from a pc power supply for my rc stuff. doubt it puts out enough amps for a car amp tho...

Yes, I hook all three to the battery bank to charge the bank then wire the amps to the battery bank. The batteries act like a reserve so I don't blow up my power supplies when drawing well over their rated current.

I have blown them a few times running 3000Ds @ 1/2 ohm on the bench before I stepped up to three power supplies. It takes out the rectifiers - which, coincidentally, are cheap, readily available, and easy to replace //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Since I bought the third one I have been running smoothly after 100s of amps tested over many months now.

Using it for a bench supply and something you'd want in your living room is very different.

Use real 120VAC amps instead...
