Conclusion: I have had four systems all having 10s or 12s pushing atleast 500 watts rms per sub.... and I was so impressed with how deep and loud these can hit they are in no way near my Two P3 Rockford 12s but they hit good base notes with out being overwellming. Right now thes 8s are being used with a Kenwood KAC-7205 and they work great to geather in custom sealed boxes in the back of my 300zx z32...
Conclusion: This little sub doesn't require a lot of power and sounds awesome. I have used this sub in outdoor applications. The latest was a golf cart paired with an MB Quart Marine amp and two Polk Audio 5.25". The setup sounds amazing. I would definitely recommend this sub. It's not over powering but just right and it comes at a great price.
This item is the perfect solution for most projects

Conclusion: This item is very cost effective and has great sound depth and speed. I would choose 8" over 10" or 12" any day because or their performance. Added to that, it is dual voice coil which that in itself makes it better.
Conclusion: used 2 of these subs, one in each door. along with 3 6.5 polk components per door. these provided great midrange and really filled in the frequencies where the subs couldn't hit. Gave them a solid 175 watts rms and they, to this day, take all the power like little champs. order with the matching grills. perfect match to the other polk audio products. and to top it off, no better customer service than that from sonic. thanks guys. will be back.
Conclusion: Got rid of my 2 ten inch subs and amp to make more room in my hatch. Put this sub in a ported box running off of the factory amp with a passive crossover and after market head unit. Hard to believe an 8 inch is putting out that much sound. I even had to turn the amp down a bit. I'm glad I got it. No wires, but it comes with nice Allen head mounting screws. Great value in my book!

Conclusion: Replaced the blown factory sub in my 2006 F-150 with this sub. Had to make a 3/4" spacer ring due to the extra depth this sub required. Other than that fitment was great and sound is better that the factory sub. Should have replaced it years ago!
Conclusion: I built a box for my 800 can am outlander and put Polk in it. I have never used dual voice coil until now. I must say i am very pleased with these speakers. They have been covered in mud, water, sand and dust and keep on rockin! people can't believe how good this system sounds on the front of an atv! When they die I'll buy another pair just ike them.
