i just got an 03 wrx about a month ago and i was thinking about putting one of my subs that i had in my blazer in it. ive got 2 12" IDMaxs with an arc audio 1200 watt amp. do you guys think if i just put one of the IDMaxs with the amp in a wrx it will be too loud? i had it all in a blazer before and it was loud as piss, i wasnt sure how one of them would sound in a wrx. what size box should i be looking at getting? i still have all the wires from the system in the blazer, do you think i can just use the same wires or will i have to get new ones? also, if i decide to put one of these in then i will prolly be trying to sell the other 12" and the box i had them in.
