JBL SUBBP12AM BassPro 12 12" Powered Subwoofer

The JBL SUBBP12AM BassPro 12 is a self-powered 12-inch car subwoofer system designed to add low-frequency reinforcement without pairing a separate amplifier to the enclosure. Its integrated amplifier, woofer, and enclosure provide a consolidated solution for vehicle audio upgrades. It is suited to drivers who have trunk or cargo-area space for a full-size powered subwoofer enclosure.

The built-in amplifier is rated for 150 watts RMS and 450 watts maximum power. A 12-inch subwoofer handles bass reproduction, while the enclosure is tuned to support substantial low-frequency output. JBL specifies a 30 Hz to 200 Hz frequency response for the system.

Slipstream Port Technology is used to manage airflow through the enclosure port. This design is intended to reduce port turbulence and the noise that can accompany high-output ported enclosures. The result is a focused bass foundation that can complement factory or aftermarket speakers.

The BassPro 12 accepts both low-level and high-level audio signals, giving installers options for different source units. Low-level inputs can be used with an aftermarket receiver, while high-level inputs support connection to speaker wiring. A selectable phase control, adjustable low-pass filter, gain control, and bass boost help tailor the subwoofer to the vehicle and system.

A wired bass-volume remote is included for adjusting subwoofer output from the driver's seat. The MDF enclosure combines the amplifier, subwoofer, and port in one assembly, helping simplify system planning compared with sourcing separate components. It is an appropriate upgrade path for listeners seeking added bass while retaining their existing main speakers and stereo.

Key Features

• Integrated 150W RMS Amplifier: Powers the included subwoofer without a separate external subwoofer amplifier.
• 12-Inch Subwoofer: Provides a full-size driver for low-frequency reinforcement.
• Slipstream Port Technology: Helps reduce airflow turbulence and port noise during operation.
• Low- And High-Level Inputs: Supports connection to aftermarket or factory-style audio systems.
• Adjustable Low-Pass Filter: Lets the bass range blend more naturally with main speakers.
• Wired Bass Remote: Allows convenient subwoofer-level adjustment from the driver's seat.

Design & Installation

The BassPro 12 uses an MDF wood enclosure that integrates the 12-inch subwoofer, built-in amplifier, and Slipstream port. Its black enclosure measures 22-1/2 inches wide by 14-5/8 inches high, with stepped depth dimensions of 9-3/16 and 12-1/6 inches. The complete powered enclosure weighs 34.3 pounds.

Installation requires a +12V battery connection, chassis ground, and a fused power connection; JBL specifies a 25A fuse located within 18 inches of the battery. Use the line-level inputs with an aftermarket receiver's preamp outputs, or use the included high-level harnesses with speaker-level wiring. JBL recommends qualified installation when the installer does not have the required experience and tools.
