I would suggest the rockfords. They make top of the line quality amps. Just dont go for the 2003 models. I would suggest to go for the 2004 power series amps. Check em out at rockfordfosgate.com
Definitely go with the JL 1000/1 for one it is better than Rockford and secondly you already have JL Subs why not compliment them with a nice Amp.Best feature on the 1000/1 is the regulated power supply putting out 1000x1 from 1.5-4ohm(11v-14.5v)
Thanks w7 owner. I cant wait to her them. I used to hav 3 12 w6 the old ones, thoes things hit. I had a alpine 1507 running them. I hope the 2 13w7 hit harder what do think. Also the w7 will be in a seald box. I saw the new rockford amps one there home page and those things were bad as$. If I went with the 1500bd I would have more power. Jl 1000/1 Im preaty shore is only 1000wats max power and rms, if not please let me no, thanks. most people have sed to go with the jl but is the 1000/1 anough power?
the 1000/1 is a perfect match to a single 13W7. remember that sub is dual 1.5 ohm coils, so it's a 3 Ohm load on the amp. you'll get 1.5X the power of a 4 Ohm load from the RF amp. the JL puts out its full power regardless of input voltage and load between 1.5-4 Ohms. the JL states 1000 watts RMS. real world power on a scope is closer to about 1200-1400+ watts RMS. the JL amps are severely underrated. I think you'd do better with the JL amps myself.
