Great info. I am about to change my 3.55 trac lok rears to a 3.31 Torsen rear. I will be taking it to a shop with the proper tools to get it done. This is beyond my level of expertise.
To bad they don't sell the Kicker KTS25 tweeters anymore, I will probably just go with similar Hertz DT 24.3 tweets. and the price for the sub and grill is now over $190. Damn that inflation. I'm probably going to do these to my car if i don't trade it for a new 2021 Mach 1.
