What wiring kit should I use for a Kenwood KAC-8104D amp?
Thanks in advance
You should be fine with 8ga, but I would probably run 4ga, especially if you plan on any future upgrades.
02 BMW 330Ci, Alpine DVI-9965, Alpine MRA F350 5ch, Alpine MRP T220 + 2x Kicker 6x9 FreeAir, Kicker KX1200.1 + Alpine 12" Type-R, 2-Way Security, Keyless Entry, Remote Start
The larger the wire you can get into the connectors, the better off you will be.
