Size: 8 inch Speaker XS Color: With Wiring Kit
I installed under the driver seat in a 2018 Honda Fit Sport. The Boss 8 gauge power and ground wires were pretty brittle which pissed me off. When stripping the housing, I lost a few strands which is just poor quality brittle copper. I also don't like that the bass adjust knob doesn't say "Boss" on it. It's just a generic min/max knob. I wasn't happy with the sound until I adjusted the settings to get whatever I could out of it. I maxed out the gain and bass on the amp and set the LPF to 50Hz. I then set the dash knob to max. On my Alpine W770 headunit I set the sub to the max at 15 and the LPF to 50Hz and the HPF to 50Hz for the front and rears. Only THEN did it shine. With everything maxed and LPF set to 50Hz. I keep the volume at about 20 and it sounds like a concert. I have Alpine type-R 6.5" components in the front and type-R coaxials in the rear doors. It sounds nice and full now. There is no where else to go with this sub as I have it completely maxed out. But it sounds good now. I was a little apprehensive to max it, but it has a mosfet so it sounds be fine. But maxed is the only way it sounds good and full. Makes the music much more enjoyable filling in that bottom end. ... show more

Installed under the driver seat in a 2005 civic sedan. Product was easy to install with included hardware. Does not have crazy bass, but makes sense for its size. Very small unit compared to full box subwoofers. Would recommend if you’re looking for just a little bit more. Better than nothing, but if you’re looking for mirror shaking bass look toward full size subs. ... show more
