Compact powerful sub. Thought it would not be enough in the factory position of my 02 Tahoe, but it definitely was.

Alpine SWR-8D4

I have one installed in a 2018 Dodge Caravan GT. I installed in the factory box with a custom built spacing ring to add enough depth to the box. Powered with an Audio Control ACM 1.300 amp. Thoroughly impressed to say the least. This combo hits hard and deep, especially for a single sub, and will satisfy most applications. Worth every penny and I would not hesitate to use the same combo in future applications.

Great speaker for Civic Type R

Bought this as a Scratch and Dent item, So far so good. Installed this last night along with Rockfordfosgate R2-500x1 amp and LC2i wired to my factory amp's sub output. Couldn't find one thing wrong with the speaker, didn't look brand spankin new, but had no cosmetic damage at all, just box was used. Speaker sounds amazing, wired it in parallel to get a 2ohm load. Installed in my Civic Type R, great speaker for this car. I installed it using factory sub enclosure and had to add a 0.75inch spacer ring to account for added depth and mounting holes are 195mm versus about 205 on stock enclosure. Added polyfil to inside of enclosure and added sound deadning material to outside as well as foam to areas around the enclosure.

All I can say is WOW!

I bought this to replace an Alpine S-W8D4 8" that I install in the OEM enclosure of my 4Runner. Great sound after break-in period and is powered by my Alpine PDR-V75, but I needed a little more. I didn't go this route originally because Crutchfield says it doesn't fit, so I did the math and purchased a .25 inch spacer from Amazon. Also, Polyfil and sounder dampener from Parts Express and BANG. It sounds like a 12 inch in a ported box-crazy loud and clean bass for days!!!

Sounded good for a minute before I blew it. I had to much power running to it. In my opinion these are questionable because I had a less rms rated speaker with the same ohms that lasted at least 6 months before it blew. With the correct amp these might be a 5 star

Type R for Ridiculous

Bought two of these and put them on a jl 600.1 in a ported box tuned to 37hz and was I shocked. Tight, accurate, low bass even for a speaker this size. Don't take up much space either. Recommend these for someone who wants compact set up with massive sound!

Unbelievable

I've had many subs in.my years. Never top end, just value based. 10s, 12s, 15s etc. I.picked up two of these Alpine type R 8s, thought one day I'd find a use for them. I wanted bass in my trunk, but didn't want something gaudy or huge. I built the box sealed, maybe 1.5 cu.ft. subtracting sub space. Absolutely blown away. No way a pair of 8s sound this good. Highly recommended. Wish I could add a pic.

Awesome Speakers

Absolutely the best 8" speakers I have ever heard. I swapped 2 12" kickers for these and I am blown away. The sound quality is second to non. I hear better bass, and get such a better response a lower volumes than I did with the kickers. I can listen to music and hear it as it was Intended rather than just boom boom boom... I wish I would have found these sooner. They will not move the air around at sub 35 hrtz lime 12s will, but the sound quality more than make up for that. I placed them in a ported labrynth box running 600 watts to them. I love them.

Little subs big bass

I never go by reviews because I know there is companies that pay people to do them.. I will tell you this, the review o will give is not fake.. These subs bring ridiculous bass to my 08 corvette.. Definitely recommend these subs.. Thanks to Crutchfield professionals recommending these to me..

Small for Big Sound

This little subwoofer packs a BIG punch. I built the smallest enclosure possible for the speaker and it works great. People can't believe it's an eight inch woofer, they think it's a twelve.

Alpine 8" Type R sub

I'm guessing these haven't broken in yet as they don't give the sound I was expecting for a top quality sub, as far as Alpine sells it. Mind you, I'm running these along with a pair SWS15D4. The 15s make sound like the 8s are along for the ride, even though I've got them crossed to play different ranges. Overall, not bad, but can't say that any extra cash for Type R is money well spent.
