Hey guys, I will be entering Db Drag trunk class this up coming season. Im running into a problem and was looking for advice. In trunk class I will be limited to only two batteries total, 15 volts total and 4k of power total that will be clamped at time of burp. Which sundown amp will be the best fit for me? also I plan on using either 2 nsv3 18's or 4 nsv3 12's at .5 ohms.
