About the Blaupunkt GTb 8A
Get ready to rock with Blaupunkt's GTb 8A powered subwoofer. You'll feel the bass you've been missing as the 8" spun-paper woofer pumps out the low-end thump.

At under 11" deep, this compact sub will fit in some pretty tight places.

I upgraded my auto stereo system with component front & rear speakers & equalizer yet was lacking the low bass and decided to try this sub. I primarily listen to lower volume settings and this sub is just right. Easy to install and provides the much needed "bottom end".
