Summary: A good overall amp. Good sound quality but IMO isn't worth $599! I want someone to justify the power this thing puts out to let's say a Kicker amp,a Fosgate amp and a pioneer. Side by side I don't think you will hear a noticeable difference. I bet the jl is a tad better in spec ratings than the others, but can you tell a $300 difference?? I love JL but way too expensive.
Excellent Amplifier-See below for my experienced performance specifics

Summary: A very high quality amplifier for the price. Excellent for midrange and tweeter speakers on four channels. I would recommend a larger or non-shared (single channel) amplifier for the bottom end or bass speakers. Channel separation is excellent, this is the ability to play a completely different sound from the left and the right. Good channel separation is what produces the stereo or imagery effect with the sound. It makes the sound have depth. Dynamic range is excellent.
Summary: I have this amp running a set of RE Audio 6.5 component speakers and PA 4X6 plates. I don't have the amp turned up that high and I can not believe how good this set up sounds. Even with the amp not turned up very high, when I turn up the volume it goes so loud it is almost ridiculous and still sounds perfect and crisp every time. I highly recommend this amp and all JL products.
Summary: Awesome amp. Serious performance for the price. Mine went south after 7 years of hard use. Searched hard for a used one at a decent price.They seem to hold their resale value well. Gotta love E-Bay.
