Great product
Extra flat box purchased in early October, fitted under a 206+ seat. Fits perfectly under the seat and is relatively easy to install. Just need an extra wiring kit and some time to do the connection properly.
Sound level, it's a good complement in bass, it's clear and precise (only lacks the infrabass compared to a classic box + subwoofer). Very good rendering coupled with an exploded kit.
I recommend this product if you are looking for a flat, practical, efficient and easy to install subwoofer.
