MACnonsence6 Posted May 13, 2010 Report Share Posted May 13, 2010 dont know if this belongs here or not but becouse of the ability to use a computer power supply to power low power amps would they also be able to have a battery in the mix to maybe be able to up the size of the amp or no? Quote I picked up an MTX Sw1212 powered subwoofer today. This thing sounds amazing. 130 watts, 12" woofer with a passive 12" woofer tuned to 27 hz. Moving the pictures on the walls and my girl got wet from the bass when i showed her haha. Tonight should be good haha. Link to comment Share on other sites More sharing options...

Are you talking about running a car subwoofer in your house/dorm/etc? Just hook the amplifier up to a car battery and have it on a trickle-charger and you should be fine. What amplifier are you planning to use? Quote On 6/30/2011 at 1:11 AM, 'Ray' said: Acoustical energy is free. Electrical energy is not. Link to comment Share on other sites More sharing options...
techforce Posted June 18, 2010 Report Share Posted June 18, 2010 We had a 550 watt PSU wired to a 600 watts RMS M650 amplifier running 2 12's and it worked fine... Just wire all 12v rails together, (yellow wires on the PSU molent connectors) and all the grounds, (black)and leave 1 yellow out to hook to amp remote... You will need a jumper wire on I believe the green wire to one of the ground wires to turn on power to the PSU. You will need to use rocker switch on back of PSU to turn on and off...

Reaper Posted June 18, 2010 Report Share Posted June 18, 2010 you can get over 1500 watt psu's now. so you can get a lot of power out of them. Quote Link to comment Share on other sites More sharing options...

My friend bridged the green wire and a ground with a switch, which you could also do so you don't have to play with the PSU all the time. You could extend the wires and run the switch somewhere you can easily access it. Quote Too many projects, too little time... Link to comment Share on other sites More sharing options...

But, if it didnt have a switch on the back, like a lot don't, that would be a perfect answer for that problem!!! Crap I never thought about that!!!! LOL! I even had one without a switch that we put back on the shelve for that reason! What size PSU he use and do you know what he pushed with it and how did it do? Our setup did ok...
