Frequently Asked Questions - Punch P112S4 Rockford Fosgate
What is the recommended amplifier power for the Rockford Fosgate Punch P112S4?
We recommend an amplifier delivering 200-400 Watts RMS at 4 ohms for optimal performance.
What type of enclosure is best for the P112S4?
The subwoofer works well in both sealed and ported enclosures. A sealed box (1.0-1.5 cu ft) gives tight bass, while a ported box (1.5-2.5 cu ft) provides more output and deeper bass.
What are the mounting dimensions for this subwoofer?
The top mount depth is 5.6 inches (142 mm) and the cutout diameter is 10.9 inches (277 mm). Ensure your enclosure has these clearances.
What is the impedance of the Punch P112S4?
It has a single 4-ohm voice coil, so wire it to a single channel amplifier at 4 ohms.
How much power can the P112S4 handle?
RMS power handling is 400 Watts and peak power handling is 800 Watts. Do not exceed the RMS rating for reliable operation.
Does the subwoofer require a break-in period?
Yes, break-in is recommended for 10-20 hours at moderate volume levels to loosen the suspension and achieve optimal performance.
Can I use the P112S4 in a free-air (infinite baffle) setup?
It is not recommended. The P112S4 is designed for enclosed applications only, either sealed or ported, to protect the subwoofer and ensure sound quality.
What is the frequency response of this subwoofer?
The frequency response is 20 Hz to 250 Hz, making it suitable for deep bass reproduction.
How do I clean and maintain the subwoofer?
Gently wipe the cone and surround with a soft, dry cloth. Avoid using liquids or cleaners. Check mounting screws periodically and ensure the enclosure is sealed properly.
Is the P112S4 compatible with a 1-ohm stable amplifier?
Yes, but you cannot wire a single 4-ohm subwoofer to 1 ohm. You would need multiple subwoofers (e.g., two 4-ohm subs in parallel for 2 ohms, or four for 1 ohm) to achieve that load.
