So, I decided to scout around the aftermarket shops since the recommendation of the folks here are to get a 6.5" speakers. Went to one shop who had MB Quart ESA 216 6". And another with Infinity Kappa 60.7CS 6.5".

What do you guys think? Will any of these work without too much installation hassle?
