Speakers problem front and rear

Hey guys I bought kicker ks600 for the front and ks650 for the rears and the they are both 6.5 size…but I tried to put the rears in and its a bit bigger…so idk what to do I checked the speaker size and it said that 93 integra takes 6.5s all around…any help would be appreciated thanks

The KS600 speakers are standard 6.5" speakers, [Kicker calls it a 6" speaker] using a 5" diameter mounting hole.

The KS650 speaker is an oversized 6.5" speaker, [Kicker calls it a 6-1/2" speaker] needing a 5-5/8"diameter mounting hole.

Standard 6.5" speakers all use a 5" diameter mounting hole, oversized 6.5" speakers use diff. diameter mounting holes, depending on brand and even models within a brand.

Either replace the speaker with one that fits or replace the stock speaker “housing” with a custom MDF speaker housing. 94
