Okay so I have a 3-way cdt passive setup in my 06 mustang gt.
Soundstream 150x4 (ish) Amp
The tweeters/mids are in kickpods on the floor and the midbass is up in the stock door locations.
I notice that when I turn up the volume more than half way, it seems like the highs are harsh, or rather certain letters in vocals and especially guitars ring louder and actually hurt my ears almost. I noticed Eqing down a bit in the 1-2k range seemed to help slightly, but now it sounds a little muffled. Certain genre seems worse than others.
I'm also considering buying some new door panels that have a spot for an 8 inch woofer in the doors which would allow me to go with a 6x8 coaxial setup above in the door and a larger more powerful 8inch midbass lower in the door. I'd really like to feel the kickdrums with authority.
Any advice here? I have my headunit on full pass through as well as the amp full passthrough to the passive crossovers. I was thinking of putting a different amp I have on it when I get home to see if it affects the sound at all, and that would point to my amp.
