be REALLY ABSOLUTELY SURE that speaker (when thumping) isn't touching the door.
i had a pair i did that with... they ripped in under 6 months.... LAME. (on my part)
and that tweeter is going to give horrible imaging....

tweeters are suppose to aim across the car.. not at your elbow!
off topic... but ryan, you saw my dual gauge pod, and how its basically blocking my tweeter... Has anyone seen a dual pod, with the pods at the top??
