In the '13 models, I understand that 'the Alpine system' merely replaced the super-cheap communistchinese drivers with blue-coned Alpine units...that all the rest of the system was the same. BTW, the speakers aren't 'amplified' in the sense that each driver has an amp parked on it. I KNOW that my front-door (both the bass/MR and the treble pairs), the rear-door pair, and the D-pillar pairs of drivers were not directly powered and that they were driven by sections of the main poweramp located in the LR corner of vehicle. I'm still astonished that Chrysler/Jeep/Mercedes allowed such a HORRIBLE-sounding system to be marketed.
Replacing ALL of the original system would require 10 channels of amplification, a relatively major project requiring at least 2 multichannel poweramps and LOTS of new drivers and rewiring. I'm VERY happy with my hybrid (of original and new) system of drivers and amp.
But maybe after years of using kilowatt systems with
2 block bass setups (whatever that is), probably you won't be satisfied with the original SW. My original SW has plenty of output, extension, and quality for me.
BTW, the last stages of my system rebuild will have me adding a bunch of Dynamat Extreme to the exterior of the SW cabinet and replacing the current, unmodified, fine-sounding old Alpine V12-series, 50WPC MRV-F307 poweramp with another old Alpine V12-series poweramp, this one a 60WPC MRV-F407. The '407 is one of the bandpass-filter amps with the filter controls atop the amp and also with MOSFET output transistors. I always believed that, all other things being equal (which, of course, they never are), MOSFETS sound a little better than bipolar output transistors. The '407 will get 2 pairs of new PS-final-filter caps (now-quite-expensive Black Gates no less) serving all 4 channels, and 5 new pairs of coupling caps in channels 1 and 2.
What is a '2 block bass setup'?
