Hi!, I'm looking for suggestions on speaker upgrades to a stock 2017 Elantra Value Edition. Just know that I'm 60ish mechanical guy and listen to 70/80/90's rock (Deep Purple, April Wine, Van Halen, Foo Fighter's, etc). I'm not looking for louder; I'm looking for cleaner, higher definition sound. I ordered some Rockford Foxgate 1675X2's, and basically hung one on the back door. It definitely has more high end (stock is just a woofer), but bass is lower than stock. Granted, this was a ten minute test, and I just reinstalled the original. Maybe it needs broken in? I can fabricate a spacer. The factory speaker looks pretty good; rubber surround, probably 4-5 oz magnet- pretty well optimized for the car. At this point, I'm thinking of leaving the woofers alone, and just replace the front door tweeters with 1" domes. Or find a better optimized woofer (Dayton?) Looking for recommendations. Thanx!
