I installed two 8 inchers in the back of a street rodded 1936 Graham and was utterly impressed with the sound quality of them. No one believes me when I tell them that they are only 8 inch subs.

Works well for the setup its in. Nice ouput for its size

I bought this to fit under the second row seat of my Chevy Tahoe and not only does it fit but it gives a lot of punch that I was looking for. I listen to rock and alternative so I was looking for a sub that would deliver clean crisp bass and it does the job and then some.

Nice slim design fit the space saving box I made for the trunk. Sound is good but a little on the quite side being only an 8" and that I'm currently only powering it with a 250w cheap amp.

I'm currently in Afgahnistan, but I purchased the subwoofer and had it installed and my wife said my car sounds so strong and loud. I can only imagine how I'm gonna bump my sound when I get home then I can give you a truly pure sound system opinion!

I recently installed one of these little subs into the jump seat location in my 92 s10. If you are looking for a small little sub to round out the low end of your small system, then this would be a great addition. The build of the sub is very solid, its small, and pretty stout. The push button terminals are very nice, and the overall look for this sub is very nice. In the right kind of enclosure this is a very warm sub and will add a decent amount of low end punch. It is very responsive, quick and tight sounding while still being pretty lightweight. I have this installed in a sealed enclosure so that might help. I’m still in the break in stages right now, but I’m happy with what I am hearing. I currently have the sub being driven off my MB Quarts FX4.70 channels 3 and 4 bridged and it puts out a great amount of sound. The sub is priced very reasonable for its application. However, if you are looking for something with massive output, this is not the sub for you. While still a very nice sub, it’s still an 8" sub, and you only have so much cone area. This would be a great fit for any small regular sized pickups, small 2 seat car, or if you plan to make a custom center console and just want some extra low end while saving space or looking for just a stealth install. While you can run this free air, I would not recommend it. If you are looking to do a small, simple, budget minded and hidden install, then this is the sub for you. Best of luck.

Great subwoofer for regular cab pickups. Surprising bass from such a small sub.

I had this installed in my 2008 Civic SI with hopes it would be a straight swap for the stock sub but it wouldn't fit so in the end had it bolted from underneath with some MDF.
So performance of this sub is impressive for its size, used with a 200 watt amp I had lying around, with some deep bass that's just enough but not overpowering.
The best part is I still keep all my trunk space. I would defenitely recommend this product to anyone looking to upgrade an existing 8" sub but concerned about maintaining trunk space.

The very good

I'm running one of these in my system which is sending 300 watts RMS bridged mono from an old school PG XS6600 amp. Sounds fantastic, though I warn you I'm an adult listener and have the levels set properly. Most kids don't know what their doing and set the levels too high. Rattled sheet metal at stop lights comes to mind. Yes this can rattle the sheet metal but I have my gains on the amp properly adjusted and the level is set on my subwoofer level control to the correct level. If your interested in setting your level correctly, you should adjust the level down until you can barely tell if it is present, this takes a well trained ear but in the end you'll find it more of a satifying listening experience. This is a great sub if you are interested in keeping your trunk space for groceries and want the sub to play strait into your cabin. If your planning on installing these in an enclosure in the truck with no direct access to the passenger cabin I would recommend going with two of them. The main thing is they can handle the high power and sound good too.

I recommend this product for anyone who want the same size speaker as their factory one , but with a little more bang to it.

These are probably the best shallow mount subs. In a box less than 4" deep you get great bass for super tight spaces.

This product sounds great for an 8" I have had ppl think I'm running a 12" back there. The shallow mount size is perfect for a pickup truck or place where size is limited. This sub really does bump with the proper enclosure

Ive been powering these subwoofers with a good amp for 5 months with hard hitting bass and zero problems. The best sub I know of for tight spaces.

I would recommend this product for anyone trying to install a sub in a limited depth enclosure. I installed this sub into the center console of my jeep to save room and it sounds spectacular! No kidding. I love this product. Kudos to Pioneer for developing a shallow sub series like this.

Not only does this 8" hit hard as hell, but it can also reach those really low bass notes associated with rap and dance music. I was impressed with its range and crispness.

It is exceptionally durable. The sub's face is exposed right next to where the seatbelt latch is and sometimes hit that or the drivers seat. I have not seen any indications of faltering performance other than a few scratches that occurred due to installation placement. It is a tank!

I just installed a pair of these 8 inch subwoofers in my 2003 VW GTI. I was looking for a sub that I could install in a enclosure that would not take up more than .5 ft per woofer and mount behind the area where the factory 6.5 inch rear speaker was. The TS-SW841D`s are being power by a Pioneer Premier PRS-D1100M that is being driven into a 2 ohm load ( 600 watts RMS x-over at 80hz ). When I first heard these, the bass sounds great and is very powerful for an 8 inch subwoofer!! I didn`t think it would produce large ammounts of Quality bass from being mounted in such a small enclosure. But after listining to them with some of my standard "BASS" CD tracks, I was really surprised to see how low they went ( solid all the way down to 40hz before they started to roll off ).But for being such a shallow mount 8 inch sub this thing packs a lot of punch for it`s size, I would have to say close to a pair of standard 10`s. I definetly recomend this subwoofer if your limited space and Sonic Electronix has a great price on them.

I had one of these for a month and loved it so i got another. These subs take up no room and hit really hard for an 8", no one could believe they were only 8" subs, i will buy from pioneer again

i just installed this sub in my KC Nissan Frontier. it is an excellent sounding sub with great sound quality. i highly recommend it for anyone looking to add depth (as i was)!
