Alpine PSU-300CVC Powered System Upgrade for 2016-Up Honda Civic 4-Door
Alpine PSU-300CVC is a dedicated 300 watt sound system designed specifically for 2016 – Up Honda Civic 4-Door LX, EX, EX-T, and EX-L models (excludes Touring models) not equipped with a factory premium amplified sound system.
The system includes a KTP-445U 4 x 45 watt amplifier, a PWE-S8 8″ powered subwoofer, and all the wiring needed, pre-loomed and ready to install. Alpine PSU-300CVC also includes a remote bass knob for changing the bass level from the dash.
Alpine PSU-300CVC system can be interfaced with a factory radio (non-amplified) or an aftermarket radio. The included T-harness interfaces the factory wiring in the dash, providing either a speaker-level signal from a factory radio or an RCA line-level signal from an aftermarket radio, to feed to the Alpine KTP-445U amplifier.
The T-harness also feeds the amplified return signal back into the factory wiring and out to each of the speakers, utilizing the factory speaker wires. The provided wiring includes a 10 ga. power wire, with inline fuse holder, that gets run to the battery, providing power for both the 4-channel amp and the PWE-S8 subwoofer.
Alpine provides pre-attached brackets that are designed specifically to mount both the KTP-445U amp and the PWE-S8 subwoofer underneath the passenger front seat. This means no usable space in the vehicle is taken up by the sound system.
The Alpine KTP-445U Head Unit Power Pack is a power upgrade amplifier that allows you to add higher output and more dynamic response to your aftermarket or factory installed car stereo system (without factory amplifiers).
The Power Pack employs a 45 watt x 4 channel amplifier with an unbelievably low noise floor, taking extra care to ensure a clean signal path, with no extraneous interference. The end result is a 1 Watt Signal-to-Noise Ratio of 82dB or better.
Uniquely, the amplifier distortion actually decreases at higher frequencies, resulting in a clean and clear signal where your ear is most sensitive to distortion (< 0.03% THD+N @ 1W; 1% THD+N @ rated power). The Alpine KTP-445U Head Unit Power Pack provides independent controls for the Front & Rear inputs.
Front & Rear Gains:
The Power Pack provides simple variable gain controls (speaker level: 0.5-10V, low-level: 0.2-4V) for flexibility and a wide variety of system applications.
Front & Rear HPF:
High-Pass selectable switches for the amplifier’s Front & Rear inputs allow frequency filtering for a wide variety of speakers. Choose “Full-Range” or a selectable range (60Hz, 80Hz, 120Hz) to fine-tune your crossover points (-12dB/oct.).
On the bottom panel of the Power Pack there are selectable input options to accommodate Speaker-Level (0.5V-10V) or RCA (0.2V-4V) inputs.
Selectable 2-Channel & 4-Channel options give you the control to determine source inputs, and can eliminate the need for Y-adapters.
The Alpine PWE-S8 is a compact self-amplified subwoofer with pre-installed brackets that allow it to fit underneath the passenger’s front seat, keeping it out of sight. The PWE-S8 includes a built-in 120 watt Class D amp along with an 8″ high-excursion subwoofer.
It can accept either line- or speaker-level inputs and features an Auto Turn-on circuit that will activate the amp when it senses a signal on the speaker-level inputs. An included wired remote lets you easily adjust the bass level from the front seating area.
The control can be mounted under a dash panel and gives you a level range from 0 to -20 dB, relative to the gain setting on the amplifier. Controls on the subwoofer include:
Can vary the input level from 0.2 – 4.0 volts line-level and 0.5 – 10 volts speaker-level.
Low Pass Filter:
Rotary control that can set the filter cutoff between 50 – 150 Hz.
Switches between 0˚ and 180˚.
Switches between SP IN (speaker-level input) and REM (wired remote input).
