The place I went to installed this in my engine bay. its got 0 gauge Orion wire to 2 4 gauge Kicker wires for my 2 amps. I though there were leds on this..but maybe its just mine that dont work or maybe i haave to do something. I had it and my speakers and amps installed professionally so i havnt even touched it haha. it gets the power to my wires just fine. really like it. very sturdy and good price too! =D
