Tryin to replace the front 6x9's and I'm having trouble finding speakers that will fit. Amazon says a speaker will fit while Crutchfield doesn't. Also Amazon has a ton of 6x9 that they say will fit while Crutchfield might have four. I'm assuming the problem is the depth of the speaker but i don't know for sure. I read somewhere that the max depth for the front is 2-3/4 but most of the speakers I look at are deeper than that. Also do i really need 6x9 or would 6-1/2 be sufficient? I'm tryin to get by without having a sub and i heard 6x9 will give more bass than 6-1/2. Any help is appreciated. Thanks.
