Finally! Got my wiring all done, ran 1/0 from the battery to a junction block, then 4 ga to the sub amp, and ran a 8 ga wire to power the Inverter. RCA's all run, turn-on wire ran from the head unit to the amp, everything up and powered!..... only to find out one of my subs is blown! Can't even move the dustcap, the coil is smoked... so I ordered another Powerbass 10" to replace it, should be here by Monday! So I'm jammin' to only one 10", on just 250 watts of power... but sooooo much cleaner sound than the factory speakers, especially since I can use the head unit's high-pass crossover to take the bass out of the doors.
Of course, nothing comes easy.... installed 1 1/2" long 3/8" bolts in the battery terminals, to make it easier to add other accessories/ use jumper cables... and just as I was almost done snugging down the positive bolt, I dropped the wrench. Sparks flying as it bridged across the positive and negative battery terminals, I quickly smacked the wrench with another wrench I had nearby, but not before the arc across the terminals started to burn through the handle of the wrench!!!
