ok, so about a week ago i bought a set of mb quart component speakers.
i installed them and for 3 days didnt crank it up much. I dont have subs in my car atm so its all on normal. and the bass is up on maxx.

i decided to crank it and the right speaker can handle the bass pretty good, but the left speaker keeps popping and farting like its popped or something. so i took off the doortrim an inspected it, but nothing was visibly damaged.

i took it down to the lifestyle store install shop to check it out, and told the guy wat was happening and what he did was basically not understand the problem. he just put it on high pass and tuned it so it didnt pop.

im just curious if there is something wrong with the speaker? or the connections were wrong? cos i still have the warranty on the speaker if its faulty, even though i dont think the install guy is gonna admit it was a faulty product(if it was)

wat could possibly be the problem with the speaker?
