I'm doing an audio install for a friend of mine, his Accord, I'll be putting an amp in his trunk. The amp is a 5 channel which pushes 880 watts RMS total(40x4 and 150x1). I'm wondering if I should use 4 or 8 gauge power cable to go to the trunk... I was going to go with the 8 but then somebody suggested the 4 would give it more power, more hit... just wondering if any of you experts could fill me in.. thanks a bunch!

But yeah go with the 4 guage, and you can run a bigger amp later if you want...

If your Power ratings are right, 8 guage would be too small.
Use the chart below to help you understand. I always suggest to my customers to go with 4 gauge, just because in the future they may choose to up grade there components and it is better to do it once (for them).

WG, CF, MTAPC-AB, MTAPC-D
0 awg 330 amps 2731 watts 3414 watts
1 awg 262 amps 2168 watts 2710 watts
2 awg 208 amps 1720 watts 2151 watts
3 awg 165 amps 1365 watts 1707 watts
4 awg 131 amps 1084 watts 1355 watts
5 awg 104 amps 860 watts 1075 watts
6 awg 82 amps 683 watts 853 watts
7 awg 65 amps 542 watts 677 watts
8 awg 52 amps 430 watts 537 watts
9 awg 41 amps 341 watts 427 watts
10 awg 33 amps 271 watts 339 watts
Wire Gauge, Current Flow, Max Total Amp Power Class AB (60% eff), Max Total Amp Power Class D (75% eff)
(Sorry it did not line up well, but I think you can make it out)

Good Luck and hope this helps
