Alpine does your Wrangler right

How great would it be if someone took the guesswork out of installation and offered a top-notch speaker system perfectly suited for your Jeep Wrangler Unlimited? Well, Alpine's done it. Their phenomenal Restyle PSS-21WRA speaker system includes everything you need to install a great-sounding system. Upgrading the audio in your Wrangler just got a heck of a lot simpler.

The sound

The beauty of Alpine's PSS-21WRA speaker system is that it's one-stop shopping. You'll get a 6-1/2" component system for the dash locations in your Jeep and a second system for the roll bar, each featuring two 1" silk dome tweeters for superior highs. The included 4-channel amp ups your power for awesome clarity at all volumes — a must for top-down drivers. Alpine also gives you a powered 8" subwoofer to stash under your seat for some great bass, whether your top is on or off. Altogether, this is an upgrade you won't regret.

The fit

Alpine designed the Restyle line for drivers who want to improve their sound but want to maintain the factory look of their vehicle. The PSS-21WRA sound system upholds this approach by giving you tweeter mounting gear that bolts into your Wrangler's tweeter locations. The woofers fit directly into your factory locations and in the case of the amp and powered sub, all wiring is included, complete with factory compatible plugs. Once the PSS-21WRA system goes in, you won't even know it's there... until you crank up the volume.

Features

Overview: Alpine's PSS-21WRA is a dedicated 320 watt, 9 speaker sound system designed specifically for 2015 - 2017 Jeep Wrangler Unlimited vehicles not equipped with a factory amplified sound system. The system includes an MRV-F300 4 x 50 watt amplifier, SPT-71 6-1/2"component speakers for the front dash, SPT-70 6-1/2" component speakers for the soundbar, and a PWE-S8 8" powered subwoofer. The PSS-21WRA also includes a remote bass knob, for changing the bass level from the dash, along with all the mounting hardware and wiring harnesses necessary for mounting and adapting into the factory system.

Wiring: The PSS-21WRA system can be interfaced with a factory radio (non-amplified) or an aftermarket radio, including Alpine's Restyle headunits. 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 MRV-F300 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 Main Harness 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. This harness also works in conjunction with the T-harness by providing audio in and out between the radio and both amps. Speaker adapter harnesses are provided for each set of speakers, including the dash tweeters, so no cutting into the factory wiring will be required. Inline high-pass crossovers are provided for both sets of tweeters.

Mounting: Alpine provides brackets to mount both the MRV-F300 amp and the PWE-S8 subwoofer underneath the front passenger side seat, so no usable space in the vehicle is taken up by the sound system. Two sets of 6-1/2" brackets are provided for mounting the woofers into the factory locations, both in the dash as well as in the rear soundbar. Each of the two sets of tweeters also include brackets, allowing them to sit in the factory locations, and include a threaded locking collar that allows them to quickly and easily attach to the brackets. The brackets, in turn, mount directly to the factory screw holes used by the factory tweeters.

MRV-F300: The Alpine MRV-F300 is a 4 channel amplifier providing 50 watts per channel into a 4Ω load and 75 watts into a 2Ω load. The amp can accept both line-and speaker-level inputs and includes an Auto Turn-on circuit that will activate the amp when it senses a signal on the speaker-level inputs. Both front and rear channels can also be bridged for 3- or 2-channel operation. The MRV-F300 includes the following controls:

  • Gain: The input Gain has a range of 200mV - 4V for line-level signals and 500mV - 10V for speaker-level signals. 
  • Crossover Mode: This switch has options for High-Pass, Low-Pass, and Off (full range).
  • Crossover Frequency: This dial sets the cutoff frequency and has a range from 50 Hz to 400 Hz.
  • Bass EQ: This switch lets you add +12 dB of boost at 50 Hz to the rear channels.

PWE-S8: The Alpine PWE-S8 is a compact self-amplified subwoofer that's designed to fit in tight spaces, such as underneath the passenger's seat, which is where the included mounting hardware allows it to be hidden. 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:

  • Gain: 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.
  • Phase: Switches between 0˚ and 180˚.
  • Power Mode: Switches between SP IN (speaker-level input) and REM (wired remote input).

SPT-70/SPT-71: The Alpine SPT-70 and SPT-71 front and rear component speaker sets both include 6-1/2" woofers and 1-1/2" silk dome tweeters, providing full clear sound for both front and rear locations. All mounting hardware necessary to mount them in the factory locations is included.

Customer Q&A

Q
Crutchfield asked: Why did you buy this?
A
It is supposed to be the upgrade made for my 2017 Jeep Unlimited, and the easiest to install. No need to cut and splice wires and rip out dash. Cant wait till i get it and install it. [ randy  Dec 22, 2017 ]
A
All in one custom solution for my wrangler.. Very excited about this! [ Micah  Jun 19, 2017 ]

Q
Is this waterproof like the factory system?
[ Joel  Dec 06, 2017 ]
4 answers
A
Amp and subwoofer (faces down) protected under passenger seat but not sure I would call it waterproof.
[ ROBERT  Dec 07, 2017 ]
A
No, but the sub and amp are protected from rain since they mount under the passenger seat. The rest of the speakers should be ok too due to there downward facing orientation.
[ Ellen  Dec 06, 2017 ]
A
No but the sound quality is outstanding
[ Mark  Dec 06, 2017 ]
A
No it's not
[ Dalton  Dec 06, 2017 ]
Q
Why wont this fit into a 2 door JK?
[ Jose  Oct 30, 2017 ]
4 answers
A
It might but I don't know. I'm having a friend install this for me as I don't know anything about sound systems lol
[ Lindsay  Oct 30, 2017 ]
A
I don't see why it wouldn't. All components go in the dash, sound bar, and under the passenger seat.
[ Thomas  Oct 30, 2017 ]
A
Not exactly sure but may have something to do with space under the passenger seat. It's a snug fit on the 4-door model. Any less space would be restrictive for mounting the subwoofer/amp.
[ ROBERT  Oct 30, 2017 ]
A
BECAUSE THE SEAT WILL NOT FOLD FORWARD WITH THIS INSTALLED.
[ JACKY JONES  Oct 30, 2017 ]
Q
Is this system capable of achieving that "disturb the neighborhood" and "almost shattered my windshield" bass all while simultaneously delivering that "heard every word from down the street" clarity?
[ Golden  Sep 11, 2017 ]
2 answers
A
No, but you can certainly feel it inside your Jeep. Very efficient for such a compact unit. Excellent clarity and imaging compared to stock speakers, even with non-Alpine head unit.
[ ROBERT  Sep 14, 2017 ]
