Get your soundstage back

Blaupunkt's GTx 663 DE 6-3/4” speakers offer the sonic clarity you want for your music at a budget-friendly price. They're a great option for replacing factory speakers that have lost their "stage presence."

Each GTx 663 DE speaker features an injected polypropylene (IPP) woofer for a lively response from your mids and lows. The 3-way speaker design also includes a 1" Mylar dome tweeter and 1/2" super tweeter which deliver all the details and ambience in your music. The speakers' low profile enables you to install them behind the factory grilles in many vehicles, but they also include stylish protective grilles for custom installations.

Features

Size Classification Note: Some manufacturers, including Blaupunkt, call this size speaker a 6-1/2". Because it requires a larger cutout than a standard 6-1/2" speaker, Crutchfield has traditionally referred to this size woofer as a 6-3/4". Please refer to the Crutchfield Vehicle Selector to confirm fit in your vehicle.
