Hi all,

Just updated all my ICE and with that I have put a vibe a3 amp in and since that I now have feedback through the speakers.

Currently running 8awg from the battery to the rear and then into a junction where 10awg goes to the amp and 8awg goes to the sub amp. I've been told if I upgrade to 4awg this will help. But tonight I found out tIhat there is 0awg.

Would I benefit from 0awg over 4awg?

Would I need to upgrade my fuse?

Would I need a ground isolating unit for the amp power cable?

Is this all likely to help? My cables are completely split the power is left, speakers are right.

The thicker the power cable the better quality you'll get so any upgrade from the 8awg would be good but have you looked at possibly your earth connection is not as good as it should be? I've seen it before where allthough the earth cable is touching the body the painted surface is causing a problem with the earthing of the amp, so sanded back to metal and cured the problem. Just a thought for you?
