Frequently Asked Questions

  • Does this unit replace my factory radio? No. The amplifier bridges directly to existing head unit outputs for immediate playback.
  • Will it slide under adjustable seating? Yes. The three-inch clearance clears nearly every sliding track when bolted securely.
  • Can I fine-tune crossovers from the steering wheel?
  • Does the red warning lamp indicate a blown fuse?
  • Should I vacuum dust from the rubber surround?

Thank you very much, the delivery was incredibly fast. This is really the first time that an order has arrived the very next day – I am very pleasantly surprised. I connected it to replace my old subwoofer and it worked immediately and without any problems. The sound is quite good for such a small device. The remote control isn't really necessary, but you just need to set it up once and then forget about it. Works well.

The box has dents; it needs to be installed to test it.

install in my 307 the box respects the dimensions well (compact fits under a seat) and does about 200w, it's not revolutionary in terms of sound but for the price it's worth it especially since the package comes with good cables and a volume control which is very practical if you don't want to activate the bass.
I highly recommend.

Fast delivery to bulgaria. The quality of sound is good. On high level have a little bit harmonic distortion. The bass is strong. The construction of woofer is massive.

This little speaker will surprise you. I got the 10" version, and put it in the center console of my truck. Wiring was easy as well as tuning. Compared to other powered subwoofers, you will not beat the price/performance of this speaker!
