Summary: I needed a new amp for my car and i love JL products . Im convinced this is a JL outside with counterfit internal components because of the static lact of clarity. My 240 watt alpine sounds much better than this 400 watt "JL". Only 3/4 of the channels worked.
Summary: First of all i do not write reviews at all, i dont think i am good at it but i bought this thing to run my mids and highs and got a 500/1v2 to run my pioneer 12" 1000rms sub and boy dose this work, my set up was not professionaly installed so the 500/1v2 got fried duty to lack of experience by my friends, so i decided to use my XD400/4 to run mids and bass and boy dose this thing work, i had to brige it to get enought power to the sub aprox 150rms and i also bridged...
Conclusion: Connected this unit to a couple pair of 6.5 components in my crew cab pick up. Sounds great. Replaced an RF Prime xd400.4 that smoked out in about 5 minutes under the same load. This amp was more, but well worth it. Thanks JL Audio and Sonic.
Conclusion: I hooked this unit up to my 6.5" components in a 4 channel / 4ohm configuration and was not disappointed in any way. Spend the extra $120 and buy this amp over the competitors. Money well spent in my opinion. I first bought a RF Prime 400w D-class unit that fried in a matter of minutes at 3/4 volume. Thank god it failed because I bought this one instead. Blessing in disquise! Pros: Sleek look, easy to install, crossover dial detents (awesome!), small size w/big sound.
Summary: I have this pushing some Kenwood Echelon speakers. It gets every bit of sound and power out of them. This is by far the best choice I could have made. I was blown away by the power and clarity.
Conclusion: This is an awesome affordable amp. The ouput of this amp is unbelievable. I compared this to the Alpine PDX4.1 and let me tell you this thing is worth the money and out performs the others. Great amp JL Audio. You out did yourself this time.
