JBL Amp vs JL Amp

just want to add my opinion.

i'm using a 300/4, a 500/1, and a 1000/1.  I'm very happy with my JL amps,  i cannot compare to JBL amps, as i've never owned them and don't know anyone that has either. 

Are you really stuck on JL or JBL amps.  For the money I would go with the JBL but that's a personal preference.  if you are looking at other amps look into earthquake and usamps, that is if you are willing to dish out MSRP money on the JL.  I know that both amps are rarely talked about but that's because they are not cheap.  But you will definitely get the bang for you dollar.  And because of the design of some of the the USAMPs you can alter the rail voltage and make a really nasty amp.

(from what I've read/heard/experienced)

The JL is a much nicer amp but will not put out as much power as two JBL 1200.1s. Either amp would work fine, but if you want the most watts for your dollar get the two JBL amps.
