jl 300/4

could be that his alt, and battery arent as good as yours.  But ya, about the amps, basically all your choices there are the same in quality, it dosn't get much better in that price range.  Its pretty much down to chooseing the brand you like.  Personally i would go with the JL, since you already have a JL sub amp, , keep a nice uniform system and you will be hapy sound and look wise.2003 Chevy Avalanche,Eclipse CD7000,Morel Elate 5,Adire Extremis,Alpine PDX-4.150, 15" TC-3000, 2 Alpine PDX-1.1000, 470Amp HO Alt.

he has a JBL amp not a JL amp. I would say that you arent gonna loose with either the eclipse or the JL amp. I am a bigger fan of the elipse amp but that is simply a personal preference and nothing more.double-secret reverse-osmosis speaker-cone-induced high-level interference distortion, Its a killer
