Rockford Fosgate PS-8 Punch Single 8" Amplified Loaded Enclosure

Rockford Fosgate PS-8 Punch 8" 150W Amplified Loaded Enclosure Compact Size, Serious Output

Product Overview

The Rockford Fosgate PS-8 is a self-contained amplified subwoofer system housing a single Punch 8" shallow woofer, a 150 Watt Class-D internal amplifier, and a custom sealed enclosure in one compact, low-profile unit. Designed for vehicles and installs where space and mounting height are severely restricted, the PS-8 delivers genuine Punch bass performance without the footprint of a traditional subwoofer and amplifier combination.

The cast aluminium enclosure with ABS backplate keeps the PS-8 rigid, lightweight, and resistant to the heat and vibration common in Australian vehicle boot and under-seat environments. The closed-loop design ensures the 8" shallow woofer, Class-D amplifier, and sealed enclosure are tuned as a matched system for optimised performance. With hi-level and low-level inputs, a variable low-pass crossover, adjustable bass boost, a built-in 0°/180° phase switch, flexible turn-on options, and an included remote bass level control, the PS-8 is a complete, ready-to-install solution power, ground, and turn-on wiring and mounting hardware are all included in the box.

Features & Benefits

• 150W RMS Class-D internal amplifier: Class-D topology delivers high efficiency with minimal heat generation, making it well-suited to shallow, space-restricted enclosures where thermal management is a key constraint. Draws less current from the vehicle's charging system than an equivalent Class-A/B amplifier.
• 8" shallow woofer in a sealed closed-loop enclosure: The shallow driver profile and sealed enclosure are engineered together as a matched system, producing controlled, punchy bass response across a 25 Hz to 150 Hz frequency range accurate and musical rather than boomy or one-note.
• Cast aluminium enclosure with ABS backplate: Unlike MDF-bodied competitors, the cast aluminium shell provides superior rigidity, heat dissipation, and resistance to the humidity, heat cycling, and vibration common in Australian vehicle boot and under-seat environments.
• Ultra-low profile at 8.3 cm depth: At just 83 mm deep, the PS-8 fits under seats, in shallow boot floors, behind panels, and into locations where even slim MDF enclosures will not. Purpose-built for modern Australian vehicles with limited cargo floor depth.
• Hi-level and low-level inputs: Connects to aftermarket head units via RCA (low-level) or directly to factory speaker outputs via hi-level inputs. Left and right high-level inputs are summed internally no additional line output converter required for factory system integration.
• Variable low-pass crossover (50 Hz – 120 Hz, 12 dB/octave Butterworth): Set the crossover frequency to match the capabilities of your existing full-range speakers, ensuring clean integration with no frequency overlap or gap in the audio spectrum.
• Built-in adjustable bass boost EQ: Add low-frequency emphasis to taste without an external equaliser. Useful for compensating for the natural bass roll-off in open-air, hatchback, and vehicles with acoustically compromised boot spaces.
• 0°/180° phase switch: Align the PS-8's output phase with your main speakers for coherent, integrated bass reproduction across all seating positions.
• Remote/DC offset/signal sense turn-on selection: Three turn-on methods in one unit. Use a remote turn-on wire, DC offset sensing, or signal sense whichever suits your specific head unit and installation type. Particularly useful for factory system integration where a remote wire is not always available.
• Remote bass level control included: Adjust bass output from the driver's seat without accessing the unit. Included in the box no additional purchase required.
• Short circuit, thermal, and reverse polarity protection: Three independent protection circuits guard the PS-8 against common installation errors and operating faults. Reverse polarity protection is especially valuable for DIY installs where wiring mistakes can occur.
• Quick disconnect power and signal connections: Removable connectors for power, ground, remote, and signal simplify installation and allow the unit to be removed and reinstalled cleanly without cutting wires.
• Complete wiring and mounting hardware included: Power wire, ground wire, turn-on wire, and mounting hardware are all in the box. Everything needed for a full installation without additional accessory purchases.
• CEA-2031 compliant: Power ratings comply with the CEA-2031 standard for amplified subwoofer systems, providing a verified, comparable power specification.

Technical Specs

Compatible With

• Factory (OEM) head units via hi-level summed inputs and signal sense or DC offset turn-on
• Aftermarket head units via low-level RCA inputs and remote turn-on wire
• Vehicles with severely space-restricted installations: modern sedans, hatchbacks, SUVs, and utes with shallow boot floors
• Under-seat mounting applications in utes, dual-cabs, and SUVs
• Vehicles requiring a complete self-contained bass solution without a separate amplifier or enclosure
• Rockford Fosgate RCA cables and signal accessories for low-level integration

Frequently Asked Questions

Do I need a separate amplifier to run the PS-8? No. The PS-8 has a 150W RMS Class-D amplifier built directly into the enclosure. Connect power, ground, and an audio signal from your head unit or factory system and it is ready to use.

Can the PS-8 connect directly to a factory head unit? Yes. The PS-8 features hi-level left and right summed inputs that connect directly to factory speaker outputs, and supports DC offset and signal sense turn-on no remote wire or aftermarket head unit required for factory system integration.

How shallow is the PS-8 enclosure? The PS-8 is just 8.3 cm deep, making it one of the most space-efficient amplified subwoofer options available. At 36.5 x 23.8 x 8.3 cm overall, it fits under seats and in shallow boot floors where standard enclosures will not.

What protection circuits does the PS-8 include? The PS-8 includes short circuit, thermal, and reverse polarity protection. Reverse polarity protection is particularly useful for DIY installations, preventing damage if power and ground connections are accidentally reversed.

Is everything needed for installation included with the PS-8? Yes. The PS-8 ships with power wire, ground wire, turn-on wire, mounting hardware, and a remote bass level control everything required for a complete installation without additional accessory purchases in most standard vehicle setups.
