Alphasonik AS120A 12" 1500 Watts with a Built-in Amplifier Down-Firing Shallow Mount Enclosed for Tight Spaces in Cars and Trucks, Slim Thin Loaded Subwoofer Air Tight Sealed Bass Enclosure

Really good crips sound. Packs a punch for sure. Deep bass The shop I had install the box was surprised at the sound for its size Definitely worth the money. I’d recommend 100%

Need 5 gauge wiring kit. Take time running wires and have a continuity test light handy for finding a good ground and to troubleshoot if amp for some reason don't have power. Has good sound. Good bass. Overall if your not looking for super loud bass that's not gonna make your ears ring. This is a good subwoofer. Have it paired with Orion 6.75" speakers. I'm happy with the subwoofer amp enclosure

Fit perfectly, sounds good. Coupled with a nice and small Kenwood amp it just works and that's the best outcome I could have hoped for. Using it as a low end filler on an all alpine speaker set 2x 6.5, 2x tweeters, 2x 6x9, and adjusted just so, it fills the low end void they left. I probably wouldn't push this sub, it will probably explode, but for filling a hole in the audio and adding some extra thumps, it works perfectly fine. Best thing I can say is be reasonable with expectations.

Amazing Bass

I put this in my Armada to replace my old one. It's not crazy or anything. It's not going to blow out your windows or win and contests. But it does rattle the truck and you can hear it coming up the street. The build is pretty nice and compact. I'd buy it again
