Great purchase

What a great sound I love it

Perfect For a Modest Music Enthusiast

Stock Honda Civic Si 2013 speakers are poor because there is barely any bass. I bought this at a stereo shop and had it installed, exactly the type of bass that I wanted with adjustable knob and more bass to spare! It can rattle the car if you want and can hear it while standing outside, but only if you want it too. Every song feels truer and get tons of complements for it. Save your wallet and get this very affordable speaker.

Great Speakers!

Easy install, put out a lot of sound. Just hooked in to factory rear speaker wiring for the signal. Hardest part is running power from the battery.

Great Product!

Was using a slim "Memphis" 8-inch. This sounds better and still fits behind my seat.

Excellent purchase

Great bass for the price and ease of installation

Love it

I have not seent one review on this product, but decided to buy it anyway. I picked this one because it was 350w rms and the DF was only 200w rms and needed another amp to get the 300w rms. This little this is awesome. Enough low end for what I'm looking for. It's compact and fits in the back of my Impreza hatchback. Nothing negative to say about it. They person that installed it said they couldn't use the high input because it didn't sound right. So they hooked it up differently. I look forward to driving all around now that I have a great sound and bass

Pretty good subwoofer

I like the subwoofer how it's small and convenient to put In small places. As well as not to mention it delivers a shaking bass that can be heard from a distance. I wished they had added a ventilation opening in the enclosure though and do note I found if you switch the extra bass switch on the amplifier, the sub will at high volume turn off by itself so be wary of that. But over all I recommend it!
