I have a Kicker ZR360 running 3 JL 10 WO's, a 1.1 Farad VooDoo Cap, a 2-in -- 4-out Fused Power Distribution block, and a 1-in -- 2-out fused Ground Block. If I turn the volume up too high after a period of time I end up melting the solder joints on the amp fuse at the Ground block for the amp, and the amp is only up 1/2 way.. The Power block fuses are fine, my main battery fuse is fine, my internal amp fuses are fine, and my Cap ground fuse is fine, it's always the amp ground that melts.I have 8 gauge power to a block, 8 to the amp, 4 to the cap, and a 4 gauge ground block with 8 to the amp and 4 to the Cap. It's driving me nuts, I've spent 40 dollars on fuses this month, do I need a breaker, get away from AGU, eliminate ground fuses altogether??? Is it stupid to fuse ground connections? someone experienced please reply, no "it could be this
crap", experienced replies only please, thank you for reading regardless. Erick

You should not have a fused ground, it should be a solid connection. im surprised you haven't fryed your amps yet from loss of ground. your running a very high risk of toasting your amp.

Alpine Guy is 200% correct. Fusing the ground side is not adviseable. It will not be long before you start melting the terminals on your amp if you don't run a direct ground.

Mabye Im not reading this right but to me it looks like it says ou are running 1 8guage power wire to the amp and a seperate 4 gauge power wire to the cap. Then you are running a single 4 gauge wire to a distrobuton block which you then ground both items off of. If that is right then I would suggest eliminating the ground disto block and just grounding the cap and amp to the same point on the chassis. Someone told me before that grounding the cap and the amp to the same point wasnt a good Idea but I have never had a problem with it. If someone has a good reason to not do it I would love to hear it.

Hows about (makes up a reason) it will break the thermal charge barrier of the caps ability to charge with a shared ground due to the resistance of the amplifiers power supply as it is being charged by the cap. It is also a bad idea not to check the flux fluid levels in the cap, just like an engine with oil, the cap needs to have a certain amount of flux capacitor fluid to operate safely. I agree that the ground needs to be grounded properly. Where is the ground wire attached to and remove the fuse on the ground line.

Awesome help guys, thank you. I think I will just get a straight distribution block to organize my ground connections. I have four, amp, cap, fan, and the digital power fuse block, so I'll just hook up a 1-to-4 and that should work out good, thanks again!
