Great amp

This amp is not for competition but in fact it's made for a descent sound and believe me it does puts out the rms that it say it does. I know because my friend had it on his charger and sounded off the hook.

JL Audio JX500/1 is so so

I installed this Amp with MTX Audio TR5512D 400rms 2 Ohm. And after 10 minutes (80% of max power) of work, turnes off beacuse is gettin warm I would even say is gettin HOT ! This amp is not that strong, maybe for 300w rms Subwoofer will be ok but not over that Trust me ;-)

Great Product

I really like the JL Audio JX500/1. It has great power pushing my two JL Audio 12W3 speakers. JL Audio is the best investment I've made in car stereo equipment. I've had others Kenwood Rockford Fosgate MTX Kicker etc. None of them compare to JL Audio. Thanks Gregg
