PPL, I'm in the process of building an all out SPL car. (SM 3-4) Right now, I have 2 AutoTek MM4000.1's, which will be connected to 2 ATOMIC APX18D2's. (wired@ 1 ohm per sub) Being a Kinetik dealer here in Japan, I can get the 2400 Monsters at a good price.. I used the calculator on the site and it said I needed 3 of these monsters! My goal is to get full power out of the amps(burps only!) How many batteries would you suggest? and before anyone suggest other batteries, I've already looked at: Odyssey 2150 NSB90 via Northstar and Optima g31 Yellow tops all comments are but experence is wanted holla when ya can TIA Gavin (MERRY CHRISTMAS AND a early Happy NEW YEAR to all!
