alright so im looking at getting a set of infinity perfect 6.5s and phoenix gold 6x9s for my 97 3.0 cl powered by a 4 channel phoenix gold amp...what is the exact mounting depth for both 6x9s and 6.5s...i dont wana have to cut anything off, i want them to fit nicely, but if i do have to cut, what would i be cutting, the 6x9s have a depth of 3 1/4...so how much would i need to cut? or should i go with a different set?
