    I have been doing lots of searching for detailed information on exactly how this is done and the safety issues wih doing this and have not found anything worth mentioning so let me lay out what i think would work and see what you guys think?

    To do so i would assume you would need the following-

    PSU with single 12v rail.

    PSU with 12v rail output equal or greater than the fuse rating on the amp.

    Cut off ALL 12v wires going into connectors and splice them all together to form the rated 12v output ready to connect to Power input on amp.

    Do the PSU trick so u can turn on and off the PSU via kill switch in the back.

    If all of this is true, then i have a couple questions.

    1-

    Most PSUs have terrible -12v ground amperage ratings.... is this ok?

    Am i suppose to hookup the negative output from the amp to all -12v wiring on the PSU? I do not understand what the -12v amps are for so i am lost on that spec.

    2-

    What are the safety issues with doing this if it works fine?

    Of course an inline fuse will be required but besides that?

    I've heard of someone running for a while and the PSU actually set fire. I can assume maybe excessive output to fast but i don't like to speculate about things that might burn the house down, hehe

    My Electronics is pretty buggy at the moment. But I will tell you what I know.

    Its ok to run your Amp from a PC PSU (SPMS) - but you need to kind the right kind of Amp and SMPS. Your Amp should not use dual power supply (+12V, 0V, -12V).. because as you pointed out -12V in PC SMPS is not having enough Ampheres to power your Amplifier. The -12 V in SMPS is used for serial communication in PC's as far as I know. So if you use -12V, expect the SMPS to catch fire.. :Doh:

    But if your Amplifier uses only +12V and GND (ground), you might be in luck.. Most SMPS available today could have enogh juice to power your Amplifier..

    You should know that this is an option if you have a spare PC SMPS.. If you are buying a new SMPS, you could buy a SMPS specialized for your Amplifier...

    I hope we can all be friends on this forum. As Rodney King said, " Can't we all just get along." Reply as if you are talking to the person face to face. That will be difficult, I know.

    :D

    I will try my best to get along... Can't make any promises - don't know when I would hit on the head or kick your a$$ - I would be ok as long as I get my meds.. :angry22:

    Greetings,

    I am Joe, aka OnYrMrk and I have been competing off and on for about 20 years. I have competed in Thunder On Wheels, IASCA, Car Audio Nationals, USACi.

    I am a USACi SQ Judge and started off the 2006 season with a sponsorship from Focal. Love the product, love Orca Distributing, but left because they wanted me to sell my Audison amps and run STEG or Focal. I am on a limited budget so I reluctantly left Focal without burning a bridge.

    If you get to work with them, Nick Wingate is a fantastic ear to tune your car.

    I have now created Team Non-Conformist

    we are small, we don't carry any sponsorships, we paid for our own equipment, and we compete

    I look forward to speaking with you all in the coming days. I like the looks of this forum.

    --Joe

    Wow, Thats quite a CV...

    Yeah, the MJ is a great sub from what I've heard as well. I'm wanting to do a cube of 18" subs with 4 subs on each side that is facing horizontally, and use the top face as a port. This is pretty much going to be a building shaker for Halloween, and will be powered off of a 4kW amp that I have not put to use in a long time.

    I'm talking really cheap.

    Surely, This will bring down the house.. :wacky:

    Hi Guys, does any of you have a spare (or two ..lol) 8 Ohm MAW 10 Subwofer that you are willing to give out? I am looking for one and I will pay by using paypal. I had contacted mach5audio.com and they had only 4 ohms MAW10, and they don't use paypal.

    If anyone's willing please quote the price including shipment to India.
