Alpine SBR-S8-4 Slim Box Car Ported Enclosure with one 8 inch Type-R Under seat subwoofer 1000 watts Power

I have loved Alpine R speakers for years now but this little, in size only!, speaker is amazing to me with the 8" speaker preforming as good as it does! Have Dodge Ram extended cab truck and it fits right under my back seat on passenger side perfect! I did have to remove my bottle jack and flatten out the tabs for it to make speaker fit just right but the trade off was well worth it. I could have put on drivers side but I have my tool bag on that side with straps and other men toys that I prefer on that side of truck for easy access. Thanks for another great R speaker. Between my son and I they are now a family tradition! LOL!

Its small, well made, provides tight punchy bass. I didnt want to take up too much room from my cargo area but i also wasnt about to get a powered sub and i was dead set on a matching alpine system so i got this to set in back and the mrv-500 to mount under my rear seats. I absolutely could not be happier with it!

This little guy really bumps for an 8in subwoofer! Really impressed!! I have it in a regular cab Chevy and was want more bass than the power sub I had. Got this and it blew me out of the water with the quality and performance. I’ve had people ask me if I had a 12 in my truck and when I told them it was an 8in they were extremely shocked. Also I have it hooked up to alpine 500w mono amp.

sounds great in car. it's a small enough subwoofer for a tight space. works well in my trunk. buy it.

Really happy with this little sub! Exceeded my expectations!
