Best Value for Money

I've heard a lot of 6.5" coaxials, from extreme top end to entry level Pioneers and Alpines. I owned a pair of Pioneer TS-G1643R which are basically entry level. When I replaced them with the Polks, the difference is STUNNING. Running them through the Alpine Power Pack (45x4 RMS) they sounded absolutely amazing. In my opinion Polk Audio offers the best value for money in car audio and these are absolutely no exception. You can't go wrong with these speakers.
