Why Choose This Product?
The BGS-CX64SL combines a slim 6.5-inch woofer with an integrated compression driver for installations that need both shallow mounting depth and a two-way speaker design. Its paper cone, cloth surround, and titanium diaphragm give you distinct component details to consider when choosing speakers for a compact vehicle audio setup.
Installation & Compatibility Notes
Measure the mounting location before purchase. The speaker requires a 5.57-inch / 142mm baffle cutout and 3 inches / 77mm of mounting depth. Allow for its larger overall diameter and depth when installing the grille: 7 inches / 178mm across and 4 inches / 103mm deep.
The speaker is rated at 150W RMS and 4 Ohms. The recommended high-pass crossover is 140 Hz. The supplied installation guidance names 75–150W RMS per channel at 4 Ohms as an amplifier pairing range, and identifies the SoundQubed S4-100 and Q4-150ABv2 as example models. Confirm your mounting location’s clearance and your amplifier’s requirements before installation.
