I just bought a new audio system for my car. I have a 1998 corolla le. I bought dual 12" 400 watt (800 total rms) mtx jackhammer speakers in a sealed enclosure and to power it I bought a hifonics brutus 1200 watt amp. I'm going to buy the 4 gauge cables needed pretty soon but I want to know if i should be looking for anything else like capacitors, new batteries, or anything else that'll help me keep these running sharp. I appreciate any suggestions. Thanks!
