This sub is awesome i buy it like a month ago and it put my pioneer premiers to sound like crazy. It has an excelent audio quality and for the price is much better than the Boss C350 or Boss Ch350 that doesnt have crossover.
This amp is worth the money for the sound it puts out. If you are starting to put something together with little money this one will work. This is my second one.
This amp's best feature is its small footprint. It fits easily under the driver seat of a Jeep Wrangler. The sound quality is suprisingly good. I doubt the power ratings are true, you are more likely to receive 40% of what they say because the amp is only fused at 20 amps....., something like 20W RMSx4 at 4ohms, and 40W RMSx4 at 2ohms. I have this hooked up to 4x6 Sony Xplod 4-way speakers up front, and 5.25" JBL GTO (2 ohm load) component speakers (5.25" in sound bar, and tweeters mounted in A pillar). Pioneer entry level head unit and Power Acoustik 8 awg wiring kit. The SQ is very good. Now the next test is its reliability..
Excelent amp. Small and powerfull, I have 2 6.5, 2 6x9 and 2 8" bass and goes perfect.
