Polk Audio DB842 SVC - DB+ Series 8" Shallow Subwoofer for Marine/Car Sound System, 30Hz-200Hz Frequency Response, Single 4-Ohm Voice Coils & Polypropylene Woofer Cone

Love it - great bass from a small package!

Sounds great paired with a cheap Taramp's TL 1500 amplifier. I can't believe one sub sounds so good in my El Camino.

I bought this as a replacement for a factory speaker, and the difference is night and day. The Polk Audio DB842 sounds so much better, cleaner, deeper, and overall more powerful. Installation was straightforward, and it instantly upgraded my sound system. Very pleased with the quality and performance. Highly recommend if you’re looking to upgrade from stock speakers!

I built a sweet DIY bluetooth party speaker for my daughter's softball teams walkup music. I got this sub to install under the speaker box and let me tell you, it thumps hard! Very clean, tight bass. I'm running 200 watts to it and there's no clipping or distortion, it's a great subwoofer.

Great speakers! Works well, stong bass

I have an MTX amplified bass tube in which I blew the original speaker. This one fit perfectly into the enclosure and once broken in and tuned, makes great bass for my application. Highly recommended replacement woofer for lower powered systems or oem dealer subs.

I am running all Polk speakers so I wanted a matching sub to go along with it. This unit is perfect. I have not yet installed but I have high expectations that this unit will perform as well as all previous Polk products I have used...Only issue.... Made in China!!!!!!!!! This is getting ridiculous and stating on the unit "Designed and engineered in US" means nothing. Come on Polk, you can do better than this. I would have paid more for made in the U.S.Bring back the C4 subwoofer and I would buy one (if you made it here!Update 10/8/22Finally got all the interior replaced in truck with new stereo system & wiring installed. This sub absolutely pounds!Current set up is Kenwood Excelon KDC-X705 deck, Kenwood amps (KAC-PS704EX 4/3/2 channel running front Polk 6.5" coaxials on A channel and this sub bridged on B channel. KAC-PS702EX 2 channel running Polk 6"x9" 3 ways. All speakers mounted to doors). Sub is mounted in a sealed enclosure behind the seat (where the fuel tank was installed from factory) that incorporates the amp rack.This is all installed in a very well insulated '65 Chevy truck. Even in a bigger vehicle I would not hesitate to recommend this sub to a properly wired and powered system. The clarity and tight bass is just right for my application and makes a huge difference in the overall sound quality; especially in such a small space.

Nice product just be sure to used appropriate power for peak performance
