Features

  • 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
  • Specs - Dimensions: 12.20 x 8.86 x 2.95, Weight: 8.82 lbs. LED status indicator. Thermal, Short and Overload Protection Circuits. High Performance Voice Coil. Rubber Surround. Aluminum Cone, Remote Subwoofer Control

Description

Much like the engine of a new automobile, a new subwoofer must go through a short but important process of “break-in” before it is run under harsh conditions. The “break-in” process will ensure the subwoofer is able to perform as it has been designed to. This process involves subjecting the subwoofer to no more than low-to-medium volume levels for a number of hours in the enclosure. 3-4 hours is generally sufficient for the subwoofer’s suspension to loosen enough to prevent the voice coil(s) from overheating and causing failure. The break-in period is also effective in extending subwoofer life. Over-driving the woofer before it has been properly broken-in will usually result in premature failure and poor performance. Systems with a built-in amplifier do not require the addition of an external amp. They already have the power to play louder. High-level inputs accept speaker output signals and low-level inputs accept pre-amp output signals to allow for the addition of amps and processors to standard factory or aftermarket source units. Metal Oxide Semiconductor Field-Effect Transistors quickly switch from full to non-conduction for high efficiency output. Our Class-A/B amplifiers feature specific linear circuitry that increases sound quality and power output while reducing distortion and improving efficiency. Variable low-pass filter gives you control over the frequencies that pass through to the subwoofer. Variable Bass Boost allows you to adjust the low bass within the boost range to just the way you like it. The Variable Input Control allows the amplifier input to match the output signal from the head unit to achieve optimum performance when adjusted properly. Low-profile subwoofers are a great choice for space-constrained areas without compromising on power and performance.

  • Great option for a budget setup
Size: 8 inch Speaker XS Color: No Wiring Kit
Good option to add to a budget or stock car audio setup. Won't impress anyone but it fills in that missing thump and low end. Do note that this doesn't come with any of the required wiring, so make sure to pick up a wiring kit (I got some cheapo kit here on amazon for like $12, just make sure its at least 10 gauge) and I wired directly into the rear speaker wire. Out of the box it's set to a base non-tuned setting so won't sound good at all - you NEED to tune and adjust the settings on both the sub and your head unit. Read the manual, it explains how to set the gain. I think I ended up somewhere with the gain set to 3/4, bass boost almost near max, and the high pass filter a half or turn up from middle (this is important if you're regular speakers don't produce a lot of bass). I also turned down my head units "bass boost" setting from +3 to +1 as the regular speakers don't need to try and fill in bass anymore and let them shine more in their minds and highs. ... show more

  • Good subwoofer until you can afford something better.
Size: 8 inch Speaker XS Color: No Wiring Kit
It’s fine. Gets quite warm during normal function and it doesn’t sound quite as good as my other 12” 1200 watt Rockville Sub. Acoustics overall are lacking. Affordable is great though and works great as a “hold me over” subwoofer until you can afford something better:

  • Fits under the driver seat in my PT Cruiser
Size: 8 inch Speaker XS Color: No Wiring Kit
Good sound. The first one I bought gave out after a couple of years, but it looks like a factory defect. Still, at the current price, it beats anything else I have found. When people get in my car the scan the back area and are amazed at the sound. Using with a Kenwood in dash media player. Great sound with no loss of cargo space. ... show more
