Summary: I researched every subwoofer amplifier Crutchfield carries. I read all the reviews. For a sub amp, class D is the only way to go since anything else might overheat and turn off automatically. What really caught my attention was the THD of .2% on this.
Pros: clean, clear sound, screw-in connections.
Cons: make sure the air flows around it to keep it cool
Summary: I already installed the MRV-F300 and new speakers in my '15 Corolla and decided to beef up the sound more with the MRV-M500 and subwoofer. The combination created fantastic overall sound. Don't go cheap on your speakers...be sure to match quality with quality.
Summary: Picked up this little guy to drive my JL 12W3. Sub is rated at 500 rms, and that's what this amp runs at. Nice match! Been breaking everything in for about a month now and have not had any amp cutouts. Not even once! Great product from alpine.
Pros: Size,price, quality, fit my specific needs perfectly.
