hey all.
a while back i bought a JVC head unit with AUX and USB input for my car. i later bought a pair of FLi 6" speakers for the front and a pair of sony 4" speakers for the rear. it's an mk2 5 door.

the sound overall is very, very good, but i have to turn it up quite loud when the car is in motion because i can't really hear a lot, and at that point the problem is, my passenger door rattles under the pressure of the bass i get from my FLi speakers. what can i do to prevent this?

also, are uprated tweeters worth it? i've got the standard ones in atm.

thankss

Sound deaden the doors? Tbh with fli crap there is no point in uprating tweeters your better investing in a decent set of components and amping them.
