Features

  • Built-in Amplifier Low-Profile Subwoofers that are amplified do not need an external source and are generally very compact
  • MOSFET Power Supply - With a MOSFET power supply you get improved switching speeds, better performance with less power from the driver, lower gate-to-drain feedback capacitance, lower thermal impedance for higher switching frequencies
  • 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 & Low Level Inputs - A low level (RCA) input is measured in voltages. A high level (+/- wire) input is measured in wattages. Both essentially carry signal from your receiver to your amplifier to your speakers
  • Variable Bass Boost - Variable Bass Boost allows you to adjust the low bass within the boost range to just the way you like it
  • Variable Gain Control - The gain control is not for adjusting volume. It simply adjusts the amount of signal that is coming from your receiver and going to your amplifier
  • Phase Control - Phase control lets you adjust the speaker phase with the amplifier depending on the location of the subwoofer. This will avoid possible sound cancellation depending on the setup
  • Specs - 12.2 x 8.9 x 3, 8.8 lbs.
  • 3 Years parts and labor

  • A Great Value for a Small Car Audio Subwoofer.
Size: 8 Inch with Wire Kit
This little sub is really nice. The sound is clean and works very well with smaller interiors like my Impreza. It is highly adjustable and fits perfectly under a seat. It comes with everything you need to install and provides the much needed depth of sound with any stock or aftermarket set-up.

  • It really depends on your factory system.
Size: 8 Inch with Wire Kit
I first installed this I'm my truck, I thought I'd get a bit more bass out of my music, to be fair my truck already had a Bose system, so unfortunately it didn't work out. I did have the intention to install this in my commuter which only has a simple factory 4 speaker system. So I did just that and what a difference. This is a lower budget speaker and for what it cost it's a great deal, this puts out equivalent bass to my truck, the quality isn't there as far as clear bass but for overall I definitely recommend. The key was to get a bit more base without having to dump $$$ on a system. I'm definitely happy about my car now, makes my commutes more enjoyable. ... show more

  • Not bad, not great - better than not having it
Size: 8 Inch with Wire Kit
Does what it's supposed to do: adds a little extra Bass to the total overall sound while not occupying too much space. FYI, while running at full strength, I measured about 5-7Amps at 12V. I connected it to the same power wires that feed into my radio which has a 10A fuse. Running my radio + woofer at full blast did not blow the fuse. So connecting the dedicated thick wires from the car battery is too much hassle and pointless. This tiny little thing does not draw too much power. As a side note, I have a 2015 Subaru WRX where they sell separately a Kicker subwoofer. The official cable harness for that factory subwoofer connects to the same power cable that feeds into the stock radio. So I did the same procedure with this one. The build is pretty sturdy: closed metallic aluminum casing. It does not have a bass reflex hole - which could have generated a louder sound. I had to connect it to my existing speaker wires, as my radio does not have a separate SW out. The bad part: running the radio at medium volume, you can hear this SW quite loudly. Sometimes too loud for the current volume. However, when increasing the volume on the radio, the subwoofer power does not increase with it too much. It falls behind. So at loud volumes, the subwoofer feels too weak. And again at low volumes, the woofer is too loud and annoying. You would need to constantly adjust the separate SW volume level as well at different volumes - which is inconvenient, especially while having to drive. Because it does not increase its volume too much at high levels, it does not distort the sound - so that is a good thing. Overall I am 70% happy with the acquisition, especially because I did not want to pay $500 for the factory woofer or lose trunk space with a regular tube one. ... show more

  • Good deep bass
Size: 8 Inch with Wire Kit
This thing is awesome. I installed it in a 2004 Chevy Colorado where under seat space is very limited. I was thinking about buying another one to install under the other side rear seat, but I don’t need it. This one gives me all the bass I need

  • Definitely false advertisement
Size: 8 Inch with Wire Kit
Don't waste your money. Bought this on my wife's account. Brought it to a guy that installs systems, alarms etc. He looked at it then looked at the fuse. Looked at me and said straight up. You not going to get anything more than you already have in your vechile already no extra bass are sound. I didn't have the time to do it myself. I ended up hooking it up. He was absolutely right. No extra even though it says 800 watts. I get the same sound out of my factory speakers I already have in my jeep. This is junk don't waste your money on it. Packed it back up sent it back for a refund. Definitely false advertisement. Ill pay the few few hundred to get the sound I want and get the real 800 watts I m looking dor ... show more

  • Great value and excellent installation hardware
Size: 8 Inch with Wire Kit
Come with EVERYTHING you need for install. Wire is quality, controls are quality, unit itself is heavy and feels well constructed. Absolutely BUMPs in my 2001 forester under the passenger seat at like half volume. If you use the RCAs, make sure you have both plugged in (if you headunit only has one out, get a splitter!). ... show more

  • Tiny amp with tiny sound!
Size: 8 Inch with Wire Kit
Not impressed at all! Actually disappointed as he'll! Paid professional to install and the first words out of his mouth when he handed my keys was "it's not very loud". Im so bummed with this purchase and would send it back if I had known before installing. Save your money and go with something else. I based my decision to purchase on the excellent reviews given. I'm not impressed! ... show more

  • Jeep TJ upgrade
Size: 8 Inch with Wire Kit
Happy with range and performance, and the aluminum construction is sturdy. Placed under the rear seat of a 1998 Jeep Wrangler TJ that didn’t have the stock subwoofer in the center console. Ran the 4 wires in a 1/2” wire loom on the interior driver’s side from the battery and stereo (don’t forget to splice in the remote wire (blue one) on the back of the stereo as the subwoofer needs that to recognize the power on sequence. I didn’t use the additional min/max control unit (it’s optional) as I didn’t want more stuff on the dash. Set up the unit for the low pass, and I did place an inline 10 Amp fuse in the power line as I had several from another project. Earth shattering low frequency bass? No, but it truly has enough to fill in the gaps of the other speakers that just don’t quite get there. Make sure you mind the 180 push-down button as when in the wrong position it sounds like a V-Twin was idling nearby. For the money not a bad option at all. ... show more
