i currently have 2 rockford fosgate t1 12 in subs i was thinking of add 1 12 t2 to get more boom is this a good idea? bad idea? suggestions?

shouldnt mix different subs

^^^This. Either get more T1's if you want more, or get a different type of woofer. Are they in a prefab box? If so, building a properly designed box for those will usually yield more output, without paying for more woofers.

even if they are in custom boxes and runs off different amps?

Yes, even though.

[pro-rabbit]

What is your current setup? Any images or specs on the amp(s) and enclosure along with electrical?

Many times fixing a "weak" point in the system will net a better result then trying to "cram more in" will.

Yeah I combined subs once, thinking that it'd be okay cause they were about the same power. Not only is it a bad idea, but it's nerve-wracking to think that something may go wrong.
