Our Product Research Team

At Crutchfield, you'll get detailed, accurate information that's hard to find elsewhere. That's because we have our own in-house Product Research team — they open the box, verify contents, check the owner's manual, and record dimensions, features and specs. We stay on top of new products and technologies to help people make informed choices.

Features

Overview: The GTb 8A amplified subwoofer features a 75-watt RMS (150-watts max) amp and an 8" subwoofer housed in a ported enclosure.
