*Boomer response curve (SPL) is geared towards people looking for maximum loudness. This style box will be louder than the flat response curve at some frequencies, has a high impedance rise, and can utilize an amplifier rated at a slightly higher RMS than the subwoofer.

*Enclosure recommendations do not account for subwoofer, bracing, and port displacement.

Bio 8 w/ 400.1D amp and 4 gauge CCA wiring kit

Caught a flash sale at the same time I was building a small system in my wife's car. Wanted something small, discreet, and a low end fill in for her daily driver. Sub worked perfect with my small space requirements in a custom made sealed downfiring rear console box. The amp fit perfectly under the passenger seat and disappears into the interior of the car.
Review on the Bio-8 4ohm sub: Performs very well in a small sealed box! Great sound quality and impressive punch on bass drum kicks as well as low end sound fill in on musical numbers. Ran the sub for a week underpowered to break in and just set the amp gain to max RMS at 2 ohms and WOW! This little sub absolutely pounds for what it is! Very clean sounding. I thought the weight of the sub and the box would be enough to hold it in place, but I think I'm going to need to strap it in as it's actually jumping around a little bit on the floor in the rear of the wife's Versa Note! I will definitely be purchasing from CT sounds again! Outstanding quality for the price!
