OK i decided i am going to wire my JL 13W7 to .75 Ohms i am going to be using a US amp Merlin D3 2000WRMS which is one OHM stable. I was wondering is this to much power for 1 of these subs and is his going to kill my amp . I have big 3 done, Orbital 78DT battery .

You are most likely going to need an HO alternator to run that amp.

You DEFINITELY need one of you're going to run .75 ohm.



Lower impedance = more current draw = blown amps, if you do it with an inadequate electrical system.

Ok with a true 2000wrms from a class D amp, you are looking at around 200-220A of current draw.

The amp should be ok at .75ohm, but you had better have the electrical to back it up. You can install it w/ your current electrical system, but check the voltage at the amp while playing. If you are getting substantial drops in voltage (which you most likely will) beef up that charging system.

30 amps could make a big difference you should have got the 200
