The STA-8 features a Class A/B mono amplifier perfectly matched to power the 8-inch woofer in its vented enclosure design. We developed a compact trapezoid shaped enclosure, perfectly tuned to get the most out of the proprietary 8-inch subwoofer. The geometric design maximizes transient response, reducing the negative effects that a small enclosure can have on the subwoofer by dispersing and dissipating standing waves away from the subwoofer and the result is cleaner, deeper bass in less space.

Supplied with “plug in” connectors for speaker and power installation is simple and straightforward. The addition of dual mounting straps means the BTA-8 can easily be taken out of the vehicle when extra space is needed. Also since no holes need to be cut the BTA-8 is a perfect choice for leased vehicles that could use a little extra bass.
