  • Space Saver - If you are tight on space, this is a great solution for you. The combination of amplifier and subwoofer all into one, makes this ideal for spatially challenged vehicles. With a slim design, there are a few installation options
  • Pulse Width Modulated - PWM simplifies power supplies. It controls the output voltage and current precisely by not only removing the output current sensing loss, but also eliminating all secondary feedback circuitry. Efficiency. Increased reliability
  • Variable Low-Pass Filter - A low-pass filter is an electronic circuit that removes all the notes below the filter's frequency setting. You will use the Low-pass filter to primarily keep high notes out of your subwoofer(s)
  • High Level Inputs - Speaker level inputs are commonly referred to as high-level inputs. It will be used to connect the BASS8 to your factory radio or an aftermarket radio that does not have low-level (RCA) inputs
  • Low Level Inputs - Line level inputs, also known as RCA inputs or low-level inputs, use RCA interconnect cables to link the BASS8 with the source unit. Most aftermarket radios have multiple pairs of RCA outputs that can connect to multiple amplifiers
  • Variable Bass Boost - Variable Bass Boost allows you to adjust the low bass within the boost range to just the way you like it
  • Phase Control - Phase control lets you adjust the speaker phase with the amplifier if your speakers or subwoofer are hooked up out of phase

  • Awesome bass!
Size: 10 inch Speaker XS Color: No Wiring Kit
The media could not be loaded. Great little sub! Installed it in my 97 Chevy OBS and works great for my application. Also a great price, great fit and super easy to hook up.

  • Big sound, small package!
Size: 10 inch Speaker XS Color: No Wiring Kit
This little thing really impressed me. I needed some stronger bottom end power in my 2012 Nissan Pathfinder. I have a Kenwood DMX8709s installed with a pair of Kenwood 6x9s in the front, and they sound good, but they distort at higher (or even mid) volume with bass turned up even a little bit. That's where this sub comes in. I wired it under my driver's seat and while it did take a minute of time to adjust my EQs and crossovers to remove the bottom end load from my speakers and onto the sub, it does an amazing job. Sound is crisp and tight even when turned way up past normal listening volume. In terms of the type of audio quality, I would describe this sub as tight and punchy. It doesn't hit the extremwly low frequencies that you might get from a proper ported sub enclusore (20hz or so), but it does much better than full range speakers. It seems to respond down to about 25hz, but it gains quite a but more response above 30hz. If you're listening to hip hop and expect street rattling bass at nearly inaudible low freqiencies, this isn't the sub for you. If you want premium audio system sound *inside* the car that you can feel and that suits virtually every other genre of music very well (seriously, everything from jazz to metal to chill beats sound amazing) and you don't want to sacrifice cargo space, this is where it's at. You will need to spend some time tuning EQs and crossovers, but it can be made to sound awesome. I can't believe it's this small and this cheap. I haven't attached the included brackets because it sits comfortably nestled when wedged between the seat anchors which allows me to slide it out of I want to make adjustments and it doesn't move when the vehicle is in motion. I picked up a boss 8 Guage wiring kit and it worked perfectly for my application. Great work Boss! Super happy with my purchase. Any thoughts I had about potentially returning it before I installed it are entirely gone. ... show more

  • Wow
Size: 10 inch Speaker XS Color: No Wiring Kit
Great unit!! Really packs a punch for a sub/amp combo unit. Definitely was not expecting that sound quality from it. It does have a few drawbacks to it. I would recommend using the 4 gauge wire instead of the 8. The ports on the unit are a little big and it’s hard to get a good connection. Wiring instructions could use some updating. The negative wire (black) only comes long enough to go the chassis and not the battery as shown. The volume dial has to be plugged in or the unit will not work. Instructions make it sound like it’s just for the remote control but in the troubleshooting portion you will find it as a common problem. I didn’t spring for the remote control as I deemed it an unnecessary option so I didn’t bother to plug the dial in until I had power and no sound. It does take some time to dial everything in to meet your own standards of the quality of sound you want. I would recommend this product for the quality and price. It has the trunk rattling capability if that’s what you desire but also has the ability to be just a great sounding speaker with the highs and lows. ... show more

I’m really pleased with my purchase. Sounds amazing for such a small profile speaker. The bass hits way harder than I thought it would.

  • Not bad for the price
Size: 10 inch Speaker XS Color: No Wiring Kit
I git this for my 1970 c10. Theres no room behind the seat and barely any room under it. I bought this it was the lowest profile sub i could find that wasnt a cheap chinese brand no one ever heard of. I let it break in properly. After that, the bass kind of seems the same. Not a very good hard hitting clear sounding bass. But for the money, i would say its not bad. ... show more

  • Just what I wanted
Size: 10 inch Speaker XS Color: No Wiring Kit
I have high standards but I wouldn't call myself an "audiophile". I'm not looking to rattle the neighbors windows or brag about my sound system at a car show: I just want to feel the kick of the beat when I'm in the mood to crank up the stereo and I want it to sound good. My old car had a pretty killer sound system: mid to upper range Alpine all around, with a 10-in kicker sub in a custom box in the back. I probably spent around $2,000 on all of the hardware - twenty years ago. I tell you this so that you understand I know what decent quality sounds like. Could I have spent three times this amount on a similar, more prestigious brand mini sub? Yes. Would I notice the difference between this sub and that one? Absolutely. Is the price difference worth what I'm looking to get out of it? I don't think so. This sub was easy to install, fits behind the back seats in my pickup truck, and once I got the gain and boost tuned, it does exactly what I want. Combined with some nice door speakers and some sound deadening pads, I think this sub is a great addition to a base sound system. I'm willing to bet that a lot of the complaints here about lack of clarity or bass sounding muddled has way more to do with the fine tuning of the sub/amp, as well as the tuning of the other speakers in the doors then it does with this subwoofer. I'm all around very happy with this purchase. ... show more
