[QUOTE="Ceezer, post: 3044358, member: 561993"] I was looking at the wire guide stickied above and had a few questions. The amp in question is a Dinstinct Audio by Crossfire 4-channel 700 watts A/B (not sure of the model number). I have it powered with 8 gauge, I'm pretty sure. The front channels are running my 6.5" Pioneer coaxials in stereo and the rear channels are running my (2) Alphasonik 10s bridged. The gain on the front channels is at about half-way and the rear gain is at about 3/4 way. So... 1) If the amp is 700W, am I running a large enough power wire (provided I'm correct in thinking it's 8 gauge) or should I bump it up to 4ga in accordance with the above guide? 2) I'm running a 60amp fuse. Is that ok? 3) I was told not to have my ground wire any longer than 18". That really restricted my wiring and I had to stretch it to get it grounded, but I found one. Is there any truth to that 18" thing? 4) What does that ~50% efficiency thing mean? 5) I think I'm running 16ga from the amp to the speakers/subs. Should I increase that to 14? Thanks for any help!
