First off, OP can fit 6.5's, but he NEEDS to make sure he is recieving aprropriate spacers/baffles with his speakers. Both front and rear stock locations fit 5x8's, FYI. Not hard to work around, but just giving a heads up so he doesn't suffer sound quality issue [from poorly sealed speaker area].
Looking nice and being nice are 2 different things. Thos Lanzar have a high RMS, but could have pathetic midbass response. For example, my Type-R comps boast being able to hit 35 Hz, which is very low. But it can hit that at about 10 RMS. get anywhere near the rated RMS, your having to crossover at 80-100 HZ depending on song because the speaker sounds like it is playing ping pong.
Also, it has the name Lanzar on it. Not that they haven't been good int eh past, but their new stuff doesn't shine much. I'd have to listen to them first. There is no sensitivity shown, so they could be in the low 80's area, requiring more power to make them loud. I'd only feel safe throwing 200 RMS at these if I got them.
