Currently drive a 2002 Tahoe, i think stock alternator push 130 amps. Standard battery. Looking to power 2 15" L7 @ 2 ohms w/ a kx2500.1. Also have 300/4 JL Audio powering 2 sets of eclipse components. Cost is a factor. Looked at DEKA INTIMIDATOR D34 YELLOW TOP. No idea on an alternator yet, but if you guys think the amp rating is good enough i might not change it out. Any suggestions appreicated!
