Right i've got a JBL 75.4 and its all wired up correctly and working but when i turn volume up over 30 on the HU it will work for 5 mins or so and then cut out for a second then work for 10 secs then cut out for 10 again.
When I turn the volume down to 28 though all is well and good.
I thought it was a power problem because I'd wired it with 10 gauge
and iv now replaced that with 4 gauge but the problem is still there
Anyone have any idea what the problem could be? I was thinking maybe the ground wire isnt large enough? Any help welcome
