I've got a single amp that's like 1600wrms (it's a 5 channel amp) running off a tiny century battery, 0awg wiring to the back, 0awg ground... I have no dimming issues... Engine noise is another story (it's just sitting in the boot atm.. I have yet to properly install it)
I think it's more the fact it's just sitting in the boot, which is all metal, and has like a few mm thick rubber mat in there... that and the headunits ground is pretty terrible... >.> might send a wire all the way back to the battery, to be safe.. or unscrew the carpet and attempt to find a spot to ground it >.>
so the cause of engine noise is nothing more than what is called a "ground loop"
Its caused by a few things.
1. the amplifier ground isnt very good, so it actually tries to ground back through the RCAs up to the headunit.
2. If the amplifier is screwed/bolted to directly to the chassis/boot/metal/ it causes the ground to feed straight back from the wire, to the body of the amp. So what the best thing to do is, get some sickaflex, and glue a bit of 16mm mdf to the floor, and then screw the amp to that.
haha, I really should make a temporary false floor... It's not bolted down xD
But yeah, I need to find my sandpaper, or buy some more to fix up the ground properly... I did scratch off some paint for the ground, but yeah.. I do need to fix the amp ground a bit better, and fix the headunit's ground too...

Yeh make sure it aint a rusted area or is not prone to moist or wetness
