Boss Up (feat. Teddythelegacy) [Explicit]

  • Full Range - With a Full Range amplifier you not only have the option to run your speakers, but also your subwoofers.
  • Variable Low-Pass Crossover - Subwoofers reproduce sound based on a number of different low-range frequencies. You can set exact sound specifications for the bass frequency reproduction.
  • Fixed High-Pass Crossover - Speakers reproduce sound based on high, low or mid-range frequencies. The High-Pass Crossover gears specifically towards “highs” in all size speakers including mid ranges and tweeters.
  • Variable Bass Boost - With Variable Bass Boost you have the control of exactly how much BASS you want to pump out to your subwoofer(s).
  • Low & High 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.
  • Specs - Dimensions: 16.22” x 6.89” x 2.22”, Weight: 7.32 lbs., Speaker Impedance: 2 Ohm, THD @ RMS Output: 0.01%, S/N Ratio: 90 dB, Frequency Response: 10 Hz to 30 kHz, Fuse Quantity: 2 35 Amp ATO Blade.
