You can buy the Kinetik HC2400 from Audio Savings | Welcome to AudioSavings.com. Their asking price is a little over $300, but they'll accept a $300 offer. I've bought several of them for that price from audiosavings...i need a second battery as well. this just keeps getting better and better. where can i find these danm things?
Just because you saw it "running" doesn't mean it was performing as it should. When you're talking about adding a "true" 2,000 watt amplifier to a bone stock electrical system with a 100 amp alt, it's going to cause trouble. Voltage drops can destroy your equipment, man. Even with the h/o alt, you'll need a battery upgrade. It doesn't have to be a second batt, though. You could always buy a single massive battery for under the hood...why ccant i run the 2 12s and amp from my battery that i have know. ive seen two 16 kick comps and a 2000 watt amp run off a 4 banger eclipse ho battery.
I'd use a nice "car audio related" battery if I were you. Kinetik is my favorite...i might look into that casue i need a new one anyway. does it have to be a special quik discharge like the secondary audio batteries?
