I have a chevy 4 door truck and have the excelon fronts. is it worth it to upgrade to the excelon rears? there is a $30 dollar vs $60 dollar price for either set. I have an alpine pdx 4.150 and from my understanding there is no coaxial (built in 2-way is what I must have) that is rated at 150w rms at 2 or 4 ohm. I have 3 12s. Would the excelons be noticably better at all besides a 15 w rms increase? Most of my music is burned as well. Thanks
