rotwiler said:They are listed in my signature 6802CF...The Polks I have in the back seat are Polk DB570. The Polks don't have as crisp highs, but do sound very good and do not require a seperate amp. The Infinity's are 92 db sensistivity and the Polks are 93db sensitivity. Comparing the stock speakers to either of these speakers is a night and day difference..The stock speakers are weak sounding..full range speakers and they sound muffled..Adding either of these speakers will make even a stock HU sound better...any efficient speaker should sound better than the stock ones. I like the Polks in back, so the highs are not overpowering...Comparing the stock to these, the stock ones were half as loud.
Thanks for the info. Thinking about upgrading the speakers since they are mos def the weak link in the oem sound. Does your car also have the separate tweeters below the A pillars in the doors? IF so did you disconnect them or leave on? Wondering if they would degrade the overall sound w/ new speakers any. I do like their placement for imaging, but...
