My bass blew out my speaker an I don’t know how to take it apart to check the inside… It’s like a short in it cuz it cuts in an out… What do I do

Here’s how to get into it Brookstone Big Blue Party/360 Speaker Battery Replacement

For checking speakers, I use a multimeter with a resistor measurement to check that the speaker is not shorted and I displaying the correct impedance: 2ohm, 4ohm, 8ohm, etc., whatever it is supposed to be. With the speaker leads disconnected from the amp, of course. Then take a one and a half-volt battery and touch your speakers leads a few times. You should get a “pop” noise that sounds relatively clean—-a bad speaker will give you a harsher “scritching” sound if the voice coil has been overheated and deformed. Note: a one and a half-volt battery will not harm your speaker if not continuously applied. Switching speakers around, or “borrowing” one from something else will tell you if you have amplifier problems.

I have the same problem with BBP speaker ( it fell down and some abnormal voices from bass speaker) To pull down the cage u need to open the bottom and main botton silver ring ( by small screw driver push it up) and also Aux and supply frame( it has 6 screws which are located under rubber plugs) After all these things done u need to pull down the cage (it may stuck at first you can force it by an screw driver as a leverage between the cage and upper lid
