    Fast delivery from this seller and well packaged! Product is a good bit of kit. Installed it into the factory system of my covered camper van to give abit of depth to the system as it was very hollow with just the front speakers, and it does the job perfectly. Install was easy, cut 4 wires in the factory loom and attach to the 4 wires from the subwoofer loom, connect to the battery and you’re away.

    Very good. My Mini Cooper sound system wasn’t great now this has been added it sounds so much better. It’s so compact and fits under my glove box (mounted) I am very happy with inphase sub. I would recommend it if you sound system is quite and you want volume a bass.

    Perfect, good sound and great installation instructions. All wires you need supplied in box. Included remote which help you get the best sound whilst in the drivers seat. Fits perfectly under the seat also.

  • Quality sound

    Sounds amazing and adds an extra bass to my standard stereo 🤩 Didn’t fit under my seats because my seats go up and down so had to install it behind back seat. My son bolted it on with the brackets it came with and hid it out of the way.
