kickass audio Posted February 6, 2011 Report Share Posted February 6, 2011 try this. set your multimeter to impedance/ohms. (its the one that looks kinda like a pair of headphones) - put your test leads on the positive and negative terminals of the speaker (doesnt matter for polarity to test resistance in this case) - read the resistance, if its less than the rated ohm load than its blown second slightly push on the speaker directly in the middle (DO NOT put a ton of force into it) - if its hard to move or makes a crunching noise then it is definitely blown third smell the speaker - if it smells burnt or like hot glue then its blown up. let me know your findings. im a pro at blown speakers because thats all i ever do. lmfao.

kickass audio Posted February 6, 2011 Report Share Posted February 6, 2011 i figured you would ask this. sorry for not saying. look at the back of the speaker. normally the manufacturer puts them on there as a sticker or if the speakers are stock they are printed right on the magnet or motor of the speaker. usually after market ones are 4 ohms and stock tend to be 8 ohms from my findings.
