and I need to change it to at least a 4awg and was wondering what the easiest way to do it would be? where should I pull the wire through? And how big of a fuse should I be using on a 4 gauge thats only a few feet long? 150amp enough?

Depends on what you are doing??? What are you doing?

What is the benefit to making the change?

tiny wire is definitely a problem

first things first, the 8 gauge from alternator to battery is too small and definitely needs to be changed, too much juice being sucked out and not enough being fed.
Capacitors help with burps, but when the bass is very frequent the caps don't have enough time to charge and just put even more strain on the electrical system.

Change it out and let us know how it works.

2 JL 500/1s and a JL 300/4, but I'm getting serious dimming

I'm thinking one cell on your battery is about to go.. Afterall winter is about done...bring it to a shop..even Auto Zone.. they will do a free load test... 1 cell bad you can still start some cars. but it will suck the power from any alternator and your systems.
