your not going to run the 12s and the 15 together are you? i would do the 2 12s with sub up and port back.

Dont mix and match sub sizes, If anything, sell the 15 and pick up another 12

dont mix subs! you get cancellation and shitty sq as well as decreased spl when you mix subs

unless your 10" was used as part of a 3 way setup or something...?

The only way to mix match sub sizes is to have them fully crossed over. Like having the 12"s do 35-40+ and letting the 15 take over on the low lows...But in your case, I would sell the 15 and get another 12" or sell the 12"s and run another 15"...

ok thanks for all the advice but my question still stands in the future which is better ports up or ports back. it is a 1994 jeep cherokee and as for the mixing of subs is it really that big of a deal i havent heard much about it being bad b4. i mean i dont want 2 mess any of it up but if i do put hthem all in what would be the best way to do it
