    • Very very impressed ...and fast shipping 👍🏼👍🏼
Size: 10 Inch Style: 10” K9 Series 4 Ohm
I have too say am very impressed!! I’ve had in the pass 2 kickers L7 also 2 12 JL ‘s I’ve own plenty of 12 inch speakers with plenty of cheater amps I’ve Ben around the block as I’ve right now I still have a few cheater amps put away i still have 1 kicker ZR1000 and a ZR600 also a few ADS amps ..I own a Audi b8.5 I didn’t want to put 2 12’s in my trunk this time I wanted to upgrade the factory 10 inch subwoofer and a separate amp just for the 10 inch sub.. so I bought this 10 inch and I installed it where the factory sub was on the back top wow it almost didn’t fit I didn’t realize it was tall but it did.. I also sealed everything back there I used my alpine cheater amp as it’s only one Chanel And small amp it’s pushing 700 watts perfect for the speaker..the speaker i got was 10K9D4 4ohms wired to 2 ohms . this set up sounds nice it hits very low I have to say am impressed how it sounds.. some of my friends that have 2 12’s in there trunk couldn’t believe I was pushing 1 10 inch.. anyone reading this that don’t know to much about stereo systems keep in mind that a good brand amp comes a long way and keep in mind I have 4 cheater amps one of my amps is a true rms 1000 watt and I didn’t install that because it’s only 1 10 inch subwoofer and the most I’ll give this speaker is 600 to 700 watts Without blowing the speaker and trust me that’s plenty for one 10 inch this setup hits good in every music I throw at it ..I never owned 10 inch speakers I always went with 2 12inch ..now if I bought 2 of these speakers then I would of used my ZR600 cheater amp I still wouldn’t use the ZR1000 I would only use my ZR1000 if I had two 12’s my point is u don’t need to use a kicker ZR1000 cheater amp on 1 10 inch subwoofer u will blow this speaker ..I don’t understand y companies say 3000 watts on a speaker when true rms is 600 watts it confuses the newbies.. hope this helps someone That doesn’t know to much ..agin for the price of this speaker u can beat it ..I went with speaker because I didn’t want a box in my trunk o I forgot to mention I had a 10 inch kicker 8 ohm speaker with the factor amp before I installed my alpine cheater amp and this monster subwoofer ..5 stars for this speaker good price and well built speaker and very very fast shipping Update 2021 I ended up buying a second one these speakers with a good amp pounds I only had 1 at first I replaced the factory 10 inch to this speaker and I sounds like I have 2 12 inch subs in my car every one that hears it can’t believe the setup I have it hits nice I bought a nother one that’s how good these speakers are I have no complaint I can’t believe how well made these speakers are for the price . And the package is very well packaged for delivery.. ... show more

    • Sounds great!
Size: 6.5 Inch Style: 6.5” K9 Series 4 Ohm
Great little subwoofer! I purchased this to replace my original 6.5" subwoofer speaker that's built into my amp shelf system. Seems like it's high quality! No complaints yet, and I've had it for a few weeks so far.

    • Great subwoofers
Size: 10 Inch Style: 10” K9 Series 2 Ohm
Great subs but they didn't fit in any of the 10 inch boxes I have and had to make the openings of one box larger. Now they are hitting hard and sound amazing.

    • Good bass
Size: 12 Inch Style: 12" K6 Series 4 Ohm
These subs drop. Hope you have an amp that can handle them they hit so hard. I spent more money on dampening than I did on the speakers they're well worth the price
