Conclusion: I was using 2 jbl gt5 s12 sub's in my toyota innova, read about this sub on various sites believe me it deserves 5 star rating. It can out perform my 2 jbl subs with a ease, it sounds clean and can go very deep even with sealed enclosure. It is a only sub that can perform good with less power. My search for the best sub is over with this sub.
Conclusion: I bought these about 6 months ago and boy do they sound good. I did research on many name brand subs before finally deciding on these and I am very satisfied. The price was good but nothing can beat the base sounds that they put out, not even the price. I will never get any other subs but Polk. If you want nice sounding subs go with another brand but if you want the best sounding subs then pick up a pair of Polk Audio subs.
MM1240 1-Way 12" Car Subwoofer - EXCELLENT PRODUCT
2 February 2011
Summary: I have no complaints about the product. It came well packaged and worked flawlessly. I like the way the sub sounds with my 300 RMS polk audio amp. I will not be winning any competitions, but it is exactly what I was looking for.
Conclusion: I have one of these in my dodge durango running on a AP1200 Profile Amp and it hits hard and loud not to mention it also can hit bass in every range. I highly recommend this sub along with any of polk's products, thats all i have and they havent let me down whatsoever
