i'm currently looking at getting new Amps for my setup i'm running 4 RF T-2 15s, 2 250 amp alts. 10 batteries at 16 volts. I'm thinking about adding 3rd Alt if need be I have the 3rd one on hand. i know that sundown has 3000watt doing well over the rated output at 14.4 volts. I have heard about a new amp that is coming out and i'm very interested in running the Amps but i don't want to over load the subs to much(LOL) yes i do....... this is all installed in a 93 Jeep 4X4 Lardeo.
