i have component mb quart 4''half front 6''half back and the sound clarity is amazing across all types of music .would also recommend diamond audio .also when buying tweeters metal ones tend to really high pitchy
for a softer more precise sound i recommend silk dome.

 

my rear speakers are 4 ways with 2 tweeters on each and that was over kill on my ears. To have the tweeters on the sail panel really messed me up for a few hours

 

do u have a equalizer u must tweek to eaven out turn the treble down

 

my trebel was at zero. i dont have anything to change my hi, mids, or lows.

 

the cool thing about the mb quarts is i can choose between 6 and 8 db rite from the crossover before evan messing with the equalizer .

 

sounds like you have a crappy headunit
maybe that's your SQ problem
