In the 01 GTX the stock bose system blows asshole and sounds like crap so it is in need of an upgrade. I have had a Pioneer Permier headunit in this car forever and it still works great but I may decide to swap that out for my AVIC Z2 navigation headunit that I took out of my GXP. The AVIC Z2 is a double din and the GTX is a din 1/2 dealio to thats going to take some work. I added a Infinity Kappa sub and a JL 250X1 mono amp and the base sounds nice now. I plan on upgrading the speakers and running them straight off the headunit to bypass the bose amp that is beyond useless and I really dont want to add another amp for many reasons. I have 5 1/4 and a small tweeter in the front doors, 6X9 and 4" speakers in the rear deck. I was told to look for speakers that had a higher sensitive rating, 93 db, because that would work better with the lower wattage the headunit is going to out put. I had Infinity kappa speakers in the GXP and they sounded awesome but the highs were a little bright at times. I was recommended Polk, MB Quart, and Alpine. What the best speaker to go with in this situation?
