Cerwin Vega VPAS68 6 x 8" Powered Underseat Subwoofer

The Cerwin Vega VPAS68 is a compact active subwoofer enclosure designed to add low-frequency support to a vehicle audio system without consuming much cargo space. Its integrated mono amplifier and loaded 6 x 8-inch subwoofer combine the major bass components in one enclosure. The slim 2.8-inch height makes it a practical option for many underseat or other space-restricted installations.

This model is intended for drivers who want more bass from a factory or aftermarket stereo while keeping the installation focused and compact. It accepts either RCA low-level input or speaker-level input, allowing it to work with a variety of source units. A wired remote level control is included for adjusting subwoofer output from the front of the vehicle.

The VPAS68 is rated for 100 watts RMS and 300 watts maximum power at a 4-ohm final impedance. Its frequency response is specified at 20 Hz to 150 Hz, with an adjustable low-pass filter to blend the subwoofer with the vehicle's main speakers. Input gain, bass boost, and phase controls provide useful adjustment during setup.

Its all-in-one layout uses a built-in Class D monoblock amplifier with a PWM MOSFET power supply and thermal-protection circuit. The amplifier is integrated with a cast aluminum heatsink for heat dissipation. A high-temperature voice coil, polypropylene cone, and rubber surround support everyday mobile-audio use.

The VPAS68 can serve as a straightforward bass upgrade for systems that do not need a separate amplifier and large subwoofer enclosure. RCA input is the preferred connection when a head unit or signal processor provides RCA outputs, while high-level inputs support systems without them. It is suited to installations where measured available space and secure mounting are prioritized.

Key Features

• Compact 6 x 8-Inch Format: Adds bass support in a slim enclosure designed for tight vehicle spaces.
• Integrated Class D Amplifier: Combines the amplifier and loaded subwoofer in one unit.
• 100W RMS Power: Provides a measured power rating for a compact powered bass upgrade.
• RCA And High-Level Inputs: Connects to aftermarket radios, processors, or factory speaker outputs.
• Adjustable Low-Pass Filter: Sets the upper bass range from 50 Hz to 150 Hz.
• Wired Remote Level Control: Lets the driver adjust subwoofer level from a mounted control.

Design & Installation

The VPAS68 uses a sealed underseat-style enclosure with a black Coated Tough Guard finish. Its integrated amplifier is housed with a cast aluminum heatsink, while the 6 x 8-inch woofer uses a polypropylene cone, rubber surround, ferrite magnet, and high-temperature copper voice coil. Power and protect LEDs provide operating-status indication.

Before purchasing, measure the intended mounting area against the enclosure dimensions of 10.2 x 7.6 x 2.8 inches. Use either the RCA low-level inputs or the speaker-level inputs, not both at the same time. Cerwin Vega specifies 8 AWG or heavier power and ground wire, a ground run under 39 inches, and a 16 AWG or heavier remote-turn-on lead when using remote turn-on wiring.
