    Love jl, this amp is powering 2 pair of the focal K2 power components & sounds great. Jl may b a lil more but worth every penny

    I had a JL Slash 300/4 V2 running my mids and highs. I've directly swapped the Slash for this HD600/4 and Oooohhh it sounds so good! I believe the damping factor with the HD line adds to speaker control which refines the sound quality. Even though this amp is 150w per channel and the slash 300/4 is only 75, the difference in loudness is not overpowering but noticable. You'd think that more watts going to a 75w speaker would make it distort more but it doesn't. It provides a clean controled sound at upper volume levels. The sound quality is amazing....WOW! To top it off, this amp runs cooler and draws less from the battery. I'm running a 40A master fuse at the battery with this 600/4 and a Slash 500/1V2 and have not blown a fuse yet. Class D all the way!

    I must say this amp sounds great i have it off 6 1/2 polk sr in front and in the back. i switched from a 300/4 v/2 amp. i must say what a difference the music is a lot more clear and the power you can run to your speakers is crazy. you really get cleaner power with this amp. if you are on the fence about this amp dont be its worth every penny in my book and been into car audio 11 years now.
