Right now I'm running SQ HDS315s on a ZX1500.. I already had the amp before getting the subs so I got them in 2 ohms.. I want to increase the power on the subs so I need an amp that gets that kind of power at 2 ohms..
Well the KX2400 is $500, so I'm willing to spend about that much..
I'm in the process of moving the subs from my 99 suburban to my 07 Tahoe.. Stock electrical for now but I'm going to do the big 3 upgrade and change the batter to a yellow top.. Running 0 gauge amp kit.. Kicker amps aren't stable below 2ohms
