Gearstix Posted September 3, 2009 Author Report Share Posted September 3, 2009 Well I was bored in class today and started to think about the wiring for my stereo... When I do my extra batteries in the back, I do a run from the positive terminals to the positive bus bar, then a run from the negative to the negative buss bar. The positive goes to the amp... Where does the negative go? My other setup didn't have any additional batteries, and the amp was grounded to the chassis. Quote 2005 Blazer Build... Mach 5 SPL-12s, Audiopipe AP3000.1D..

TechSys Posted September 3, 2009 Report Share Posted September 3, 2009 Positive wire from the front to the positive buss bar. Negative wire from the buss bar to the frame or chassis. Really isn't any different than setting up a basic system, except you have more batteries in place. To answer your earlier question about fuses to the amp(s). If the amp(s) do not have built in fuses then yes, you'd want them.. unless the amps are so close to the batteries there'd be no short. The fuses in the amps are to protect the amps. The fuses from the front battery to the back batteries are to protect the positive wire and batteries against any shorts. This is why you put the fuses as close to the batteries as possible. I hope that helped out a little. I haven't ran fuses in such a long time, I'm starting to think I'm new to the scene again.

Ahh okay. So the negative coming off the battery bank has to be grounded. Then you ground the amp aswell? It didn't really seem right when somebody told me the negative off the battery bank goes into the amp. edit: Oh... this is what my wire says, I have #1. So would I use a 300a fuse? Why I'm asking, the wire/fuse guide says this.. Maximum Fuse Size00 awg 400 amps 0 awg 325 amps 1 awg 250 amps 2 awg 200 amps 4 awg 125 amps 6 awg 80 amps 8 awg 50 amps 10 awg 30 amps 12 awg 20 amps 14 awg 15 amps 16 awg 7.5 amps Edited September 3, 2009 by Gearstix Quote 2005 Blazer Build...

TechSys Posted September 4, 2009 Report Share Posted September 4, 2009 Let me try this again. Positive wire from front > fuse > long run to back > fuse > back batteries buss bar positive Ground from back batteries buss bar negative to frame. Wire from back batteries buss bar negative to negative input on amp. Positive wire from back batteries buss bar to positive input on amp. If you do not hook the negative to the frame/chassis of the vehicle, you'll not get a charge. If you do not hook the negative from the buss bar to the negative of the amp, you'll not get power to the amp. I hope I worded that right. If not I'm sure somebody will correct it for me.
