What kind of Wire Guage / Amp Kit?

[konradac 10+ year member]

I have a 96 BMW 328, and was wondering which guage wire I need for this setup? And how would I estimate a length of speaker wire, if I was just to purchase a spindle on E-bay?

Xenon X100.4 amp. (4x100w rms at 1-4 ohms in stereo)

2 Kicker RS 56.2 5.25" (90 RMS 180 peak)

and 4 Infinity Kappa 42.7i (2-50 watts RMS (150 watts peak) 2 ohms

I'm thinking the 2 front to the Kickers, and then 2 of the Infinities in Parallel for one of the rears, and 2 of the Infinities in Parallel for the other Rear Channel. Is this right?

That kind of power, 8 gauge is plenty.

So 8 gauge speaker wire or 8 gauge Power wire for the amp? Or both for everything?

Thanks!

I'd probably go with 4guage for power wires just because.. but i guess you could go 8guage. With 4guage you know your not starving your amps at all though. And for speaker wire 16 or 12guage is fine.

16 gauge for speaker,

8 gauge is enough for 1 400w amp.

If you plan on upgrading go larger on the power wire.
