how do i check to see if my speaker is blown yet or not? My speaker distort when turn loud when ever it hears big bass it sort of distort is that blown or normal?
too low of frequency for the speaker, you haven't deadened the doors well, or the speaker is not that good are all possible reasons. it may be normal it may not. i would check if you have a HPF on the amp or if its coaxials check the HPF on the HU.
