i know what you guys are going to say, do the big 3. well the scary thing is im not even running a sub. i have a 4 channel xtant amp running my mids and highs. all of my instrument cluster and gauges all dim when i crank it up. its only a frickin 4 channel. what shall i do? my battery is like 2 months old as well.

 

...you already answered your own question, big 3...2 ga or heavier, incase you ever decide to upgrade your system
