Hopefully your home speakers are 8 ohms which will keep the amp's power down so your power supply might have a chance. B+ is for the main power wire. You need to use 10 ga wire (or larger) for that. Rem is for a trigger wire to turn on the amp. In your case you will probably just need to loop a wire from the B+ terminal to the remote terminal. GND is ground. I'm not sure what the power supply provides as a ground, but you'll want to use 10ga for that as well. |

First thing he said i needed was 2x 500 watts computer power supplies, a little costly for me so i never did it. Recently Saw on tiger direct or fry's ad they were selling 500w cooler master power supplies for about 60$ each with 50$ mail in rebate or something. |
