Hello,
My Taos beats audio system was really bass heavy and muddy sounding. Surprisingly the speakers are very capable but i was getting rattles and boominess on my music. Also the car has a fairly large amount of road noise and noise infiltration. I put dynamat on the 4 doors, rear wheel wells, under the spare and in the liftgate. All told i spent around $450.00 having a pro do it as i couldn't find any diagrams on the door panels. when i got my car back the muddiness was gone in the bass region and all the resonces and panel shaking was gone, but dang there was a lot but it sounded very clean. I never recommend raising the eq but cutting below the 0 line instead as it stops distortion especially on large changes.
My settings after dynamat
Treble is -1
Mid is 0
Bass is -4
Subwoofer is 0
This is a large eq curve so cut the signal dont boost. The bass hits perfect the sound is clean and vocals sound great... Dont replace the speakers they are actually great! i would give the system an 8.5 out of 10 when before it was a 4 out of 10. Definitely sounds better the the bose in the denali and the harmon kardon in the ram. the only system i have rated higher in th4e non super luxury segment is the Fender in the Atlas...after dynamting that car i had to cut the bass to -2 and leave everything else flat......wow
