Alphasonik AS8DF 8インチ 600ワット 4オーム ダウンファイヤー シャローマウント フラット密閉サブウーファー 車やトラックの狭いスペース用 スリム薄型サブウーファー 気密密閉ベースエンクロージャー

I waited a year to write this review in order to be fair in my assessment and to also be able to speak to the durability of the product. I installed this sub in a Jeep Wrangler and powered it with a Rockford 5-channel amp that is also powering four 6.5s. I didn't want to take up a lot of space in the cargo area with a huge box and I really just wanted to round out the low end; I listen to a lot of classic rock and reggae so I was not looking to shake any windows since only about 10% of what I play falls within the rap or hip-hop genres. Initially, I was pretty underwhelmed with this sub - the first couple weeks gave me average performance at best and I did also experiment with some bass-heavy R&B just to see how it would perform. With the R&B, it produced a dull thud-like sound and with the classic rock, it really didn't sound very good when turned up loud enough to make a difference. But over the next month or so, it started to loosen up and sound more musical than noisy, and after about 3 months of moderate use, I became very happy with it. Again, I was not looking for club-quality bass, I just wanted to add some depth. That being said, it also performs very well now when I pop in some rap or hip-hop. Not a competition sub by any means, but I find myself needing to turn down the bass level for these genres. When the doors and top are off the Jeep, I'll adjust the bass knob a little higher and it is sounds great, even above the wind noise. My bottom line with this sub is that it is an excellent choice for anyone who wants to add nice tone to the lower end of the spectrum. It takes up a surprisingly small amount of space for a 10-inch, and i feel it is a bargain at this price point. The construction of the box itself is also very solid; it's had sports equipment, lawn supplies and such thrown on it, placed on it, been covered with it and a year later, it's no worse off than the day I got it. If you give it time to work itself in, you'll be happy.

Fit perfectly, sounds good. Coupled with a nice and small Kenwood amp it just works and that's the best outcome I could have hoped for. Using it as a low end filler on an all alpine speaker set 2x 6.5, 2x tweeters, 2x 6x9, and adjusted just so, it fills the low end void they left. I probably wouldn't push this sub, it will probably explode, but for filling a hole in the audio and adding some extra thumps, it works perfectly fine. Best thing I can say is be reasonable with expectations.

If you 6.5 speakers do not buy since 4 6.5 will produce more bass than this and this speaker will sound almost silent... only if you have 5.25 or less then get it otherwise is a waste of money it produces no bass and it will blow at 200w rms not worth it make sure you know what your getting into

2019 Chevy Spark install. 8 inch Alphasonik I must say I was a bit worried about how much bass this would provide. However after installing it I am surprised! It has a good range when it comes to the different notes in songs. It's not going to be knocking your mirror down or anything of that nature. It gives you more bass than you would normally have from your factory speakers. I would say about 50% more. I'm a bass head and this was a great surprise for the wife as she is not a bass head. She loves the extra bass that this unit provides to her factory setup. I have it on a boss 1000 which is not a true 1000. It puts out about maybe 300 rms. Pros: small and compact Good bass range Great price Awesome looking box Build quality Cons: Non that I can think of.

Im disappointed it just blew yestarday. It sounded great when I first installed it. Keep in mind I didnt drive the car daily. It was only a weekend casual cruiser. Its a antique car with antique plates. I drove the car maybe 4 times since the install. The bass use to hit wonderfully. I placed it on the passenger floor of my right hand drive car....Now I just hear a loose popping/rattling. I wish it would of lasted longer. I had a very very tiny 5 inch amp on it for bass. The gain wasn't turned all the way up either.
