Got 4 of these 4" to go with my meso full range 6.5. The 4" in the dash and rear doors, meso full ranges in the front doors, in my 1992 Mercedes 300te.
Sounds perfect. I was worried about them popping or distorting because I have never really had good luck with cheaper highs, but these things don't have a issue. Way cleaner and louder than what was in there. Car has weird speaker sizes and the doors really don't enclose the speaker all that well even stock, but they still do their job and I'm super happy with the way it came out.
The dash takes a 5" and I know a 5.25 wasn't gonna fit and clear the stock cover, so I downsized and the 4" actually fit pretty well with only a minimal gap to fill.
Car has a single 12 sub and a 2k watt amp, it's absolutely perfect. Couldn't be happier.
I have CT sounds products in multiple cars and they are all awesome.
Great sound they bump hard but I payed for the 2 day shipping and got them in like 5 days not too happy about that but good speakers
