JBL Marine A758 Compact Marine Amplifier
JBL Marine A758 Compact Marine Amplifier
Part Number: SKU:JBL-JBLMA758AM
The JBL Marine A758 Compact Marine Amplifier is a rugged 8-channel Class D amplifier built for boaters who need serious power in tight spaces. Delivering 1000 Watts RMS with a low-profile chassis, this marine amplifier fits easily into space-limited installations while offering variable electronic crossovers and dual input options—both speaker-level and RCA—so it works with your existing stereo, whether it's factory or aftermarket. Full onboard protection and selectable turn-on modes keep your system safe in demanding saltwater environments.
