PWE-S8

The PWE-S8 is a small but mighty amplified subwoofer system.

PWE-S8

Add a Bass Anywhere in Your Vehicle

The PWE-S8 is a compact, 120-watt powered 8-inch subwoofer that has a small footprint with impressive output for deep, powerful bass that can be installed anywhere in the vehicle.

Easy Bass Addition in Any Vehicle

More Bass, Less Space

When you're looking to make the most audible impact in your sound system, you add a subwoofer for more bass, but what if you don't have room on your vehicle for a subwoofer? Alpine's PWE-S8 measures at 3-inch deep, 13.5-inches wide and 9-inches tall for a compact subwoofer system that can be installed under or behind a seat in a truck or in the trunk of an SUV.

Durable Construction

The PWE-S8 gives you bass you can rely on, with a rugged, cast metal enclosure that's built for a rough ride, while protecting the subwoofer inside. No matter where you install the PWE-S8, the enclosure was designed for durability and performance, even in tight installation spots.

Powerful Sound

Don't let the size fool you - the PWE-S8 can hold it's own. Using a Class D amplifier rated at 120-watts, the 8" inch subwoofer is high-excursion to deliver strong bass output. A side panel gives you access to the built-in amplifier controls for phase, gain, and a low-pass crossover so you can blend your bass with your factory or aftermarket sound system.

Accessibility

Control your bass level from the driver's seat with an input for a wired remote level knob. The remote level knob has a 15' cable attached for flexible installation anywhere on the dash. Adding the PWE-S8 is easy with the easy-access RCA inputs and speaker-level inputs with automatic turn-on.

    Customers like the sound quality of the speakers. They say the sound is there, the bass is very punchy, and the quality is there. Some appreciate the option to sense sound instead of needing a remote wire. The volume in their truck is literally intolerable when turned up to level 15. However, the sound makes listening to music more enjoyable, and provides just enough heart pounding thump. The remote bass control is helpful, and customers can use their radio bass settings with this beast. They also say the bass lines come through with great detail and no muddiness.

    2014Posts: 83SyracuseOk, Phase III, subwoofer installation: I decided on the Alpine SWE-S8 powered sub to fill out the lower registers for my speakers, which roll off at 70 Hz. I decided to install it myself after seeing there were multiple existing grommets through the firewall to access to battery for power. I did a quick fit check to see if it would fit under the driver’s seat, and it did! Then I used the Pioneer factory wire harness for preamp level outputs for the line level Sub Out signal ...so, out comes the head unit again. The RCA cables I bought were not as tight as I liked, so I zip tied them to be safe. I also had to cut and resolder the Amp Turn-On line from the Maestro cable harness (Blue-White wire) for the sub (if you use line level inputs, this sub’s amp needs this 12V command line to turn on) I plugged in the Alpine remote level control as well I found the factory ground under the front passenger seat, decided to move the amp to the passenger seat, connected everything up for a power-on test to make sure everything works. PASS! Ok, now I need to find a way to get into the engine bay to reach the battery. I didn’t want to use the grommet behind the FL wheel, so I tried to find the unused one I keep hearing about “above the clutch master cylinder”. That took forever. To save everyone else time, it’s easily in the engine bay, driver’s side, behind the inter cooler. This firewall hole is NOT visible from inside the car. I popped the factory grommet from the engine bay out while trying to slice an “X” through it to pass the power cable, then used needle nice pliers to remove it entirely. Wet the entire grommet with water (or spit) and it pops back into place easily. It was much easier to pass the wire through that open hole in the firewall, then slide the grommet on after I shoved about 12” of wire in. You then have to reach all they way above the accelerator and brake, bend the grey factory noise deadening, and you can find the wad of wire you shove through. Now that the grommet is in place, you can pull the rest of the cable into the cabin. Then I routed the power cable front the positive terminal to the fender, along the top of the engine bay and into the firewall hole And with the zip ties trimmed: I routed it into the instrument panel behind the stereo and out the bottom I then removed the center console and trim panel around the shifter to pass the power cable through, along the driver’s side of the transmission hump. I passed the RCA cables, remote volume cable, and remote amp turn on cable along the passenger side of the transmission hump (to separate power and signal lines to avoid potential noise). Then, I crossed the power cable across the signal lines at a right angle at the rear of the transmission hump, and passed them under the carpeting and poked them out the existing square hole under the passenger seat. I soldered and shrink wrapped the power cable, ground cable, and remote turn-on wire and tucked excess cables under the carpeting (I didn’t want anything above the amp, out of fear that the passenger seat sliding back and forth could snag or cut a cable). I was able to fish the ground cable under the rug and over to the factory ground screw, then tighten it from the passenger seat footwell area the the larger cutout in the carpeting. I still need to find a way to secure it to the vehicle. It sits in the small “well” under the seat, but it’s going to slide around unless I secure it. I think I can use the 2 existing skinny bolts in the floor under the seat to strap it down, or come up with something to anchor it to the seat mounting bolts. I used the Velcro supplied with the amp to mount the remote level control in the instrument panel bin. I needed to relieve a small channel for the cable into the shifter trim panel. Flash used to show where I made a hole: As far as the sound, it’s great! It’s more than I need and totally completes the upgrade from the factory. The bass is very tight and controlled (at 50% of max). It probably only needs to set to 33% to really match the speakers (which are powered by the Pioneer head (22wpc max, and 14 wpc by the CTA standard). The front speakers sound much more clear now that they are high pass filtered to only what is above 63Hz. I’m not going to impress anyone with 12”+ subs in a box, but with the windows up, it’s more than I needed to make the car sound correct. The sub has a crossover frequency dial, which I should probably set at the highest frequency (150Hz), which should mean that no crossover is being used (less distortion). The Pioneer head has the ability to set crossover points for front, rear and subwoofer, and frequency roll-off sharpness. I initially set the stereo to roll off at 63Hz (the only setting between 50 and 80hz) for my door speakers, since the Alpine’s are only flat to 70 Hz. I then cross in the sub at the same frequency. I need to play with this more. I also need to re-run the Pioneer’s pink noise and SPL car calibration it does for its equalizer now that I have the sub

    5.0 out of 5 stars Perfect sub-woofer solution for Jeep TJ-Fits under the rear seat
    Reviewed in the United States on October 27, 2016
    My 2000 Jeep Wrangler Sahara had a Sony MEX-BT3800U head unit that the previous owner installed. He had a custom dual sub-woofer in the back but removed it and left the wiring when I bought it in 2012. Recently the TJ has become my daily driver so I decided to upgrade the sound system. With a convertible option on the Jeep, I decided Marine Grade was called for.

    All 4 factory speakers are easily replaced without major surgery. I got Polk dB461's for the front and dB651's for the sound bar in the back. They were a direct retrofit installed in about an hour. Great sound from the Polks. Bright and clear speakers that I'm really happy with. With the loudness on, the 651's in particular had pretty good bass but it still needed that fullness only a sub-woofer could provide. I wanted to "feel" the lows. With the wiring already in place, I considered building my own sub-woofer with a matching Polk 8 or 10" sub driver. Researching cabinets and amps, I realized loss of storage space and potential theft were significant considerations. I also don't need to vibrate the license plate. Just fill the sound band.

    A compact self powered sub is all I really needed. The PWE-S8 rose to the top of the choices. As it turns out, it fits invisibly under the back seat. I'm still tuning it but so far, the TJ sound is amazing over a wide range of music. I can literally feel the low keys resonate from piano and bass guitar passages. With adjustment capability at the head unit, I am able to experiment to find the sweet spot between sub and mains. The bass source location from the Alpine invisible to the ear. It's is all over the car. Exactly what I was looking for.

    A special note on installation and Alpine Tech Support in particular-Make sure your electrical connections are done right. I made my own ground connection on the rear seat bracket with a solid self tapping screw. Sanded the surface down to bare metal. The guys at Best Buy helped me properly run the red hot wire directly from the battery along the passenger side to the back. (The head unit wires run along the driver side. This separation eliminated any chance of interference and noise.) Then we connected to the remote-on wire (blue/white) of the head unit, plugged in the RCA connections and voila...NOTHING! No power light. We fiddled with it for about a half hour before the BB guys determined it must be the PWE-S8. I got the exchange unit from Amazon the next day thinking it will be a plug and play swap. This one didn't work either! that's when I called Alpine support and they walked me through some tests with a multi-meter. The guy emphatically said it's got to be my connection. Even though I was getting 12 volts, it dropped to 9 when the amp was under load. I know the hot was good because I saw it installed. This lead me back to the ground connection. I removed the seat bracket (2 big torx screws) and found paint on paint at the mounting point there. I sanded that down to bare metal on both surfaces, bolted it all back together and now, for real, VOILA! It worked beautifully.

    Self inflicted pain made a pretty straightforward installation a frustrating experience but I got it done. The Alpine PWE-S8 was the finishing touch on a great upgrade. My 2-3 hours in the Jeep in commute traffic is a lot better now.

    Cheers!

    Adds that nice kick to music if you have little space to add a proper sub. Install was easy, since you do not have to run a signal amp on wire. And you can steal the signal from any speaker wire.
