UNFORUNATLY Sweet is right :P ... usually when you blow a coaxial speaker the Woofer go's... not the tweeter.. takes a lot to blow a tweeter.. simply because you dont drive around with the treble cranked...
USUALLY its bass...lol
if you havent run wires directly to the speakers from the deck yet, try that too... could be bad wireing.. but they are most likley blown.
It may have been said allready.. take em out.. and push gently on the cone..
If you feel any scratchyness... or it makes poping noises during the throw of the cone they're fryed
h34r:
Thats the laymans way... the tech way is to take an ohm meter and put one to positive one to neg, and see what the resistance of the speaker is...
If its anything other than what the spec for the speaker is, the voice coil is fryed...(they arent allways EXACTLY 4ohms... but it will be close...)
And even if it reads 4, move the cone in and out.. see if it drops to 0 or changes... could still be damaged coil..
