If you tell me what type of vehicle this is going into I can design free of charge the box that you would need for optimum performance.

Stephanie it's very difficult. The glue is super strong and the screen is delicate. I hope you wiped it off immediately for much much less damage.

So I am assuming that you have just setup/wired this up recently? Have you had this working before?
You can have a look at the gain control on the amp & see if this have been set really low. This will help if the signal coming from your stereo is weak. The other thing I would suggest is to make sure that the amp can actually push this sub. I know what the specs say:

  • 1 channel audio amplifier
  • 1 x 350W RMS @ 1.0% THD
  • ThermalThrote full-on power assurance
  • 2 ohms stable (non-bridged mode only)
  • RCA type inputs
  • 0.3-6.0 VRMS input capability
  • Continuously variable High-Pass & Low Pass 50-250 Hz
  • Continuously variable Bass Boost settings (0 tp +12dB)
  • Frequency responce: 10-30,000 Hz
  • S/N >104 dBA at full power @ 0.1% THD
  • >80 dBA at 1W/1M
  • Remote gain control, mounting hardware & screws included
but I don't believe most of these. Many manufacturers embellish what their products can actually do! With the bigger more established brands such as JL Audio you will have no problems, their products have been tried & tested so much on the competition circuit.

if you have 1 sub u need a mono amp, two subs you can use a stereo amp on "two channel" mode if its NOT bridged, 4 chanel is more for 6x9s
this guide should help you alot :)

They need 1.4-1.7 cubic ft per sub(ported box) less if it is sealed but I wouldn't recommend that, it sounds like ****. Google "Re audio box calculator" and use it to adjust your dementions to your application
