Ben, Thanks so much! I'm very amused by the use of kitten to demonstrate the massive lip in one of those pictures. I suspected that cheater lips were precisely that, and it appears I guessed correctly. Also I did some more reading and they're 5.25" in the front. I just realized that my Blazer has 6.5's up front and they push pretty decent bass, and they are definitely bigger than the speaker grilles up front in the SE-R. I'll maybe reconsider having some 6.5's in the rear with a nice little amp, if it's anything like what the Blazer's Bose system would do, that should be plenty and save me room and money, methinks. Finally, thanks for the tip on the CEL codes. Now I just have to figure out where the ECU is (damn, I really am a newbie).
