figured out bad sound problem

hey everyone i posted earlier that my 6x9 aftermarket speakers sounded horrible, and i could not find the reason, well today i went down to audio inovations and did some troubleshooting with their tech. and the reason for the bad sound was that there was way too much air going inside my door panels, so i bought hushmat door panel stick ons to prevent any air going in and also caulked around the taco tunes speaker brackets since they have a big gap between the door. the sound after was day and night difference, i have way more bass now and can enjoy music!! i also topped it off with puttin in one 10 inch taco tunes sub box and one rockford fosgate p2 woofer, and put in a loc to make it work with stock head unit. alright next are 6.5 for front doors and get nice tweeters.
