i just aquired 4 infinity 5-1/4 inch speakers (they seem deep though), i have a 95 4 door blazer lt, it came with a single cd player. crotchfeel says the speaker sizes are 4x6, 6.5 and 6.75. a lot of people on this board seem to have 6.5s in both the front doors and the back doors of their 95's. are you guys useing adapter plates for the rear ones? also, when i took one of the dash grills off to check out what was under there (i didnt even know they were there for years) i found an adapter plate with a tweeter in it.
my question is, do they sell 5.25 to 6.5 and 5.25 to 6.75 adapters at my local wal mart or circut city/best buy? crutchfield wanted 14 to 25 bucks a pair! thats the price of a no-name-but-better-than-stock speakers! am i going to need wire adapters for these speakers cause i have a gm? do 5.25 to 6.75 adaptors even exist? could i just go find a peice of 1/8'' sheet metal and make my own adapters?
also the speakers i got have 4 wire harneses each, whats with that? do i need a crossover for them? they have tweeters in the middle.
