This is my second JL amp, and i must say, you cannot go wrong with their quality. And with Sonic Electronix pricing, you cant lose! Installing the amp was simple. The only gripe i have that the connections are on both sides of the amp, making cable management a little more difficult to keep clean. But the sound is amazing! Its crystal clear and does not distort my mbquart 6x9s and front components at high volumes. I love the amp and its well worth the cash. Quality is great and no heating problems yet. Very satisfied.

Customer Testimonial

It was a pleasure doing business with Sonic Electronix. The website is so simple and user friendly. I have not been this pleased with an electronic purchase in a long time. I shopped around and by far they have the best prices. I will definitely be back for another purchase!
