Review: Pricey, but superb sound and quality. - I have been a fan of Alpine car audio for a long time, and currently all the component speakers and my head unit came from Alpine. The Alpine 6x9's I have in the back do provide decent bass in their own right, but I was looking for something a little more well rounded. I listen to lots of hip-hop and EDM, so I was desperately needing an upgrade. I was considering doing a traditional amplifier and subwoofer box when I ran across this. I drive a Honda civic, so I was not in need of anything all that extreme to do the job. I am not in high school anymore, so waking the neighbors down the block was not a priority. I am useless when it comes to wiring, so I had my local Best Buy take care of the install. They had it done in about an hour. The great advantage of this device is its small and compact size, making it possible for you not to have to sacrifice cargo or people space to get rich sound. Even in my little Civic they were able to install the device under the seat, though the Best Buy guys informed me that they had to unscrew and raise the seat first to accomplish this. It's tucked neatly away and giving me maximum space and no wires sticking out anywhere. As to sound quality, unless you are a hardcore bass head I would suspect that you will be highly impressed with this little sub. It provides WAY more boom than I was anticipating given it's small size. Though also bear in mind that we are talking about a Civic here. If you rock a Suburban or some other Large SUV, this might not be enough for you. It comes with a separate gain adjustment knob that I had installed near the front center console for rapid adjustment. That said, if you have an Alpine radio that has built in subwoofer control in the audio settings, you can get much more precise control. I recommend setting the knob to about half way, and then adjusting on the radio itself if you have this setup. After you play around with it for awhile, you will get it exactly how you like it. A problem you will run into with this speaker is that turning the regular bass control down on the radio to give more power to the mids and highs of the component speakers, you will also effect the bass output from the sub slightly. To get around this, and to make sure you have balanced sound levels for lows, mids, and highs, I also had what Alpine calls a power pack installed: http://www.desertcart.com/Alpine-KTP-445U-4-channel-Power-Amplifier/dp/B003VVYL46 This can be installed directly on the back of your Alpine radio (or most factory radios I am told) and will juice up the the highs and mids from your component speakers without effecting the sub. This was a good investment also. My car audio system sounds flat out amazing now, and sometimes I just get the urge to take a drive so I can jam out. Everyone that rides with me as a passenger is similarly impressed by the range of sound my little Civic is kicking out. I spent well over a grand on everything when you add it all up (head unit, amp, speakers, this device, etc.) but if you are a music aficionado like I am, it's all very well worth it.
Review: Bang for your buck - As a 30 something with a car he'd like to keep for a long time, this was the missing piece to my sound system upgrade. I wanted something that I could live with on a daily basis. I wanted an increase in sound quality without blasting music down my block. I always wanted my system to fit in seamlessly with my stock interior. I also wanted something that was easy enough for me to install with no prior knowledge or experience installing car stereo equipment. If that sounds like you, then this is what you are looking for! I have a 2015 Jetta that had the very basic stereo set up with four speakers. I upgraded my head unit to a touch screen Android Auto unit an wanted to get more out of my music. I started by upgrading the door speakers. I have Alpine components in the front, with tweeters mounted in the upper door. The rears are Alpine coaxials. To power them, I had an Alpine powerpack installed that easily fit behind the head unit. Once I had that setup, I really liked the clear sound and mid-bass, but was missing the low end that the powerpack effectively filtered with a high pass filter in order to keep the sound quality clear on the door speakers. So I knew I needed some low end, but I did not want to install another amp and take up space in my trunk with a box. That's when I started looking for powered subwoofers that could fit under my driver's seat. This Alpine powered sub fit snugly but perfectly under my driver's. The install was also very straightforward. I did have to buy some more materials like an amp kit and some shrink wrap and t-taps to make the wire connections, along with an aux cable. After watching some install videos on youtube, I started my install. It took about half an hour, even with a bump in the install when I couldn't get the accessory power to work. I tapped into the 12v in the back and bam, the unit was powering on. I had to tune the low pass to match up with my system, and tune the gain to avoid overpowering the sound system and distortion. This powered sub will not shake your whole car, and if you've been reading up until now you'll be okay with that because it wasn't what you were looking for. If you are looking for that, you won't get very clear sound trying to get too much bump. If you tune it to complement your sound system, you get powerful, clear bass to fill in the -80 range of sound the door speakers won't play. I like having the remote level control to make minor adjustments based on the type of music playing. That allows this sub to work well with anything from punk to hip hop. Hell, it even sounds good with Mexican Banda music. I bought this through an Alpine approved vendor and paid under two hundred bucks. That made it a great value and, pun intended, bang for my buck.

**Q: Can this alpine pwe-s8 be installed in a home theater system to produce same punchy bass, if power supply is no problem?**
A: Probably possible.... power supply will be an issue 12v versus 120v and speaker ohms need to be compatible as well however 
Surely you can locate Bose home speakers to resolve punchy base issue
Good luck

### ⭐⭐⭐⭐⭐ Very tight, controlled bass
*by M***U on June 28, 2019*

2014 Posts: 83 Syracuse Ok, 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 driverâ€™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 subâ€™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 didnâ€™t want to use the grommet behind the FL wheel, so I tried to find the unused one I keep hearing about â€œabove the clutch master cylinderâ€ . That took forever. To save everyone else time, itâ€™s easily in the engine bay, driverâ€™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 â€œXâ€ 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 12â€ 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 driverâ€™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 didnâ€™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 â€œwellâ€ under the seat, but itâ€™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, itâ€™s great! Itâ€™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. Iâ€™m not going to impress anyone with 12â€ + subs in a box, but with the windows up, itâ€™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 Alpineâ€™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 Pioneerâ€™s pink noise and SPL car calibration it does for its equalizer now that I have the sub
