Features

Overview: The Kenwood KSC-PSW8 is an amplified subwoofer with a built-in Class D amplifier. It contains an 8" cone woofer, which is driven by a 150-watt RMS (250W Max) amp. The acoustic suspension (sealed) enclosure is compact enough to fit under the seat, behind the seat, or in small storage compartments. The KSC-PSW8 comes with a wired remote control to let you control its volume, phase, and the frequency of the low-pass filter.

Enclosure: The KSC-PSW8 features a specially designed acoustic suspension enclosure. It includes a 7-1/2" metal mesh grille (non-removable) to protect the woofer.

Wired Control: The active subwoofer comes with a wired remote control with a 16.25' cable. From the control, you can set the volume, and vary the Frequency Control (of the built-in low pass filter) from 50 Hz to 125 Hz. In addition, you can switch the phase of the woofer from 0°(normal) to 180° (reverse), if needed.

Connections: The KSC-PSW8 comes with a single harness with power/ground/turn-on wiring and RCA input connections. The harness has 16.25' lengths of 14-gauge power wire (with an in-line 10A ATO fuse) and 18-gauge turn-on lead, plus a 5' dual 18-gauge ground wire. It also includes a 28" RCA input for connecting the subwoofer to an aftermarket stereo via RCA cables. A 14' speaker input harness is provided for connecting the sub to a factory radio (or a radio without RCA outputs). You can splice it to the head unit's speaker wires and plug it into the RCA input. An RJ-45 jack is provided on the bottom of the subwoofer for plugging in the remote control cable.

Controls: The only controls for the PSW8 are located on the wired remote. The rotary volume control (input sensitivity) lets you match the input of the subwoofer to the output of the head unit, and to control the volume of the sub, relative to the other speakers in the system. The rotary frequency control adjusts the cutoff frequency of the low-pass filter between 50Hz and 125Hz. If you have large main speakers (6x9 or 6-1/2") in the vehicle, you can set the subwoofer's low pass filter near the 50Hz to 80Hz range. If the main speakers are smaller (4" or 5-1/4"), the low pass filter should be set in the 100Hz to 125Hz range.

Installation: The subwoofer comes with the hardware needed for installation. The enclosure installs using two brackets (included) attached on opposite ends. The power, remote, and signal connections are made in a recessed area on the bottom of the unit. The wires exit through a channel on the side of the unit. The included cable clamp holds the power, remote, and signal wires in place as they exit the channel.

Customer Q&A

Q
Crutchfield asked: Why did you buy this?
A
I installed a Kenwood car radio Dpx793bhcd and Kenwood speakers Kfc-c6895ps6 which were purchased from Crutchfield. And wanted to add this Kenwood subwoofer ksc-psw8 to round out the bass. I didn't want monster bass from some huge trunk subwoofer and this will fit the bill nicely. [ Robert A.  Aug 30, 2018 ]
A
I really wanted to enhance the sound of my music, without taking up a lot of space. Kenwood is the brand I prefer [ Mike  Mar 27, 2018 ]

The KSC-PSW8 does not provide "auto" or signal sensing turn-on capability.
