General Different gauge wiring to subwoofer

[W Bakker]

Hi all,

I just purchased a jbl basspro nano subwoofer. The subwoofer was sold in a kit with a 8awg power cable but the jbl wiring harness uses 14awg cables. What is the safest way to connect these together?

Battery - 8awg cables - included 60 amp fuse

60 amp fuse - 8awg cable - through firewall into cabin

8awg cable - ??? - 14awg cable with 15 amp fuse included with subwoofer - connect to subwoofer under driver seat.

Thanks in advance!

8AWG wire is rated for either 40 amps (3 core) or 35 amps (4 core) at 60 degrees... and is typically protected by a 15 amp fuse.

I have no idea why the kit came with a 60 amp fuse.. (if that's what you mean?) that's way in excess of the cable's capacity.

Sounds about right to me, it's not unusual to use this cable for up to 60A remembering it's not a continuous load, my 360w rms system with two amps used this cable with a 50a fuse, run the cable right to the amp assuming built in fuse
