Currently running a CDT 3-way setup in my BRZ. All speakers in stock locations. That means 6.5" in the doors, and 3" and tweets firing into the windshield. I've TA'd and EQ'd, and it sounds pretty decent. However, at high volumes with music that is "busy" (meaning not an acoustic track or vocal type track, but one that has a lot going on) I tend to lose a bit of clarity. I wonder if this has to do with the windshield bounce and the smearing effect it can cause.
I've had the thought of trying to get the drivers in the dash more on axis. Due to space, I'd have to replace the 3" with a 2" wideband and try to angle it / recess it to fit under the stock grill. Not sure what to do about the tweets (maybe try tweeterless for a bit). But then I'd need to highpass the dash higher. Right now I have them at about 450Hz, maybe I would have to take it up to 800Hz with a 2-inch?
Any comments or suggestion about this, or if it will even have an effect on the lack of clarity I experience?
