they will fit the stock door pod. just go in there, fold the jute padding down, away from the speaker. then, notice there is a reinforcing ridge protruding towards the speaker opening. get some Side-cuts, dykes, or whatever and cut this flange flush w/ the back of the pod. i successuflly installed these exact same speakers in my 89 by doing this.
with these speakers running off the 02 WRX 6disc in my supra, they are bright and LOUD. you WILL have to turn down the bass going to these speakers, install a crossover or use bass-blockers and limit the bottom end going to these things, at least 100hz blockers. i personally want to use a high pass filter coming in at 150hz.
when i turn these speakers up to drown out my unmufflered side exit exhausts, they are LOUD as hell and practically ear-piercing. when i get done driving, my ears are ringing. i love these for the mids and highs, especially considering they are very senative and do well for not alot of input power.
however, id like to get some midbass, like a 5.25" midbass/woofer and separate tweeter component set. anyone try to mount 5.25"s in these door pods?
