Satisfied

I bought this sub because of the price. I blew my last sub and wanted a quick replacement for my budget build I'm doing. I've got just one of these and I've got 650 watts RMS running to it and I was actually quite surprised on the sound. You won't be shaking your door panels or trunk off but for what you pay, its worth it. Note that I've got this running in a 94 Corolla.

If you're looking to be heard from a block away or to show off, you'll probably want to buy something else, but if you're looking for something cheap that will produce some decent bass that you can 'hear' and feel a little bit, then I recommend this.

PS I reviewed this the day I got them and installed them. I cant say anything on durability yet but I'm hoping they last.

Good Sub

I would definately decommend this sub for any application. I am running it on a tiny amp my friend is letting me borrow for the moment (120 watts) and i was thinking it would be maybe as loud as the little 8 incher i had previously had in my car. I was mistaken. It is louder than some of my friends cars, and is running on almost a twelfth of the power it can handle. I am very happy with this sub. I had to replace my rearview mirror because it was shaking too much.

Excellent value

I highly recommend the Boss CX122 sub. I got a great deal, and was very surprised at the level of performance for the price. It sounds better than a sub that I purchased a few years ago for 3 times the price.

ok

Product was installed into a bandpass enclosure. I don't recommend doing that. Specs said its ok but didnt perform to my expectations. Would like to have tried it in a different enclosure. It may have preformed better.

Great Value!

I bought this sub for a temporary because of the price. I had two Rockford Fosgates 2000watt units, one blew. I put this Boss sub in and its hitting harder than the one fosgate that's left.

Not bad

Not the greatest sub in the world but also not the worst. I got one of these in a ported box being powered by a good Alpine amp. It hits pretty hard but you wont be shaking peoples houses riding down the street. Honestly for the price I can't really complain its a good sub if your just looking to add a little bump in your ride without spending a fortune.

Great Buy!

This product is very cheap but it put out major bass! If you want a setup with 2 or more subs then i highly reccomend this sub!
