Amp wiring question - does size matter?

[Mossdahaus]

Sure it does. That sounds right on the size 4 from the battery to the unit.

I assume the smaller wire and a big power draw could potentially cause wire to melt, poor performance, or damage to the amp b/c of not enough power.

How long do you think the boat was running with smaller wire?

Do you have an in-line fuse?

Yes, both amps have fuses and I don’t think too long as dealer I bought it from said they just had them installed.

Just bought a HT6 to replace one of the HT4 amps as my winter project is to replace all of the speakers in the boat, subwoofer and add a pair of REV8s. I’ll rewire the amps and knock it out all at once.

Thanks for everyone’s help...I knew it had to be done but wondering if there was an emergent need to do so.
