Posted July 17, 201312 yr I am doing the big 3 on my 2004 Rodeo and have ran into a slight snag. I am hoping somebody on here has some advice. I am using 1/0 AWG weling cable from Airgas (Radnor Flex-A-Prene) . I Grounded the negative battery terminal and the engine to the chassis without issue. Now I am trying to attach the cable to the charging post on the alternator. The problem is that the charging post is a tiny bolt, and the lug on the welding cable is huge (http://www.airgas.com/browse/productDetail.aspx?Category=14&product=RAD64002143). The lug is too thick to be able to re-attach the nut on the charging bolt, and it is coming in contact with the case of the alternator where the charging bolt protrudes from. I am afraid that even if I manage to get the nut back on it will be grounded. I considered removing the original wire that was attached to the charging bolt, but it goes straight into my fuse box (supplying it's power I assume). Does anyone have any suggestions?

July 17, 201312 yr Author It puts out 90 amps. It's stock. Let me just tell you what I got here: Kenwood head unit on factory speakers. Soundqubed q1-2200 running a DC level 4 15 (M2) D2 4 AWG power wire fused 100A Right now I have the sub wired in series, so the amp is putting out 770 watts @ 4 Ohms. There are no problems at all, no dimming, all good. Before I run 1/0 to the back and hook up the Diehard Platimum 31M I bought, I wanted to finish the big 3. I think I need as much as I can get out my my electrical plus the extra battery if I'm going to be able to run the sub @ 1 Ohm 2200 Watts.
July 17, 201312 yr Author time for a hoaltYou're probably right, but all stock on full tilt I only drop to about 13.5V at idle. Once I get the big 3 finished, run the 1/0 to the back, hook up the diehard platinum in the back, and rewire the sub to 1 Ohm I'll recheck my voltage at the amp. If it's too low I can get a 180 Amp Alt that bolts on directly.
July 17, 201312 yr Will a 4 gauge ring terminal fit? You don't need need 1/0 for 90 amps. You might even get away with 8 gauge.If your going to one ohm you will need a bigger alt and 0 gauge. Edited July 17, 201312 yr by pmureika

July 17, 201312 yr Author I REALLY wanted to fit that square peg into the round hole. That dang terminal was $7/pair.
