Today I redid a install on a Subaru Legacy 2010. The system had:
Stock head unit
JBL MS-8
Memphis 6.5 woofers
MB Quartz tweeters
JL amps
The problems:
The previous installer said they could install a MS-8 but had no idea on how to tune it.
The MS-8 was sending out a 1 way full channel setup going to mb quartz crossovers than the signal was going to a second crossover from memphis than to the woofer.
So I ran a new wire straight from the woofers to the JL amp. The tweeters did this as well.
Than I tuned the system running 2 way active and no rears. Sounded pretty good. Customer was happy as well which is what counts.
Now the pics.
