PowerBass BTA-8  



The BTA-8 has it’s own built-in active amplifier—a first for our Autosound line up!  This vented enclosure contains a Class A/B mono bass amplifier perfectly matched to power the 8-inch woofer.  We came up with 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.  The result is cleaner, deeper bass.
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 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.
