Physically inspect the speaker.A blown speaker can have damage that can be heard with some mechanical movement. If you gently tap on the cone of the speaker it should have a firm drum like sound. If you hear a rattling sound (like a loose snare drum), this is an indicator of a bad speaker.
Jun 8, 2020 If a speaker is completely blown, it will likely not produce any sound and may just make a soft hissing or ringing sound instead. Therefore, you should listen to the speaker at a range of different volumes to determine if the distortion remains constant or if it seems to worsen.Oct 31, 2012
A homeowner can determine if a glass fuse in blown by performing a visual inspection and looking for a break in the thin wire and a brown discoloration in the center of the fuse.

Some amps use more than one fuse--pull them all out by repeating this process for each individual fuse. Home stereo amplifiers usually use a "glass" fuse located in the rear of the chassis. Twist the cap holding it in and remove it--the fuse will pop out. You won't need to pull it out with any special tools.
A car radio will have at least one fuse to protect the unit from things like power surges or other electrical issues. If too much current is sent to the audio system, this fuse will blow out and disconnect the circuit to save the main radio. On newer models, there are a variety of fuses for the entertainment system.
A. Fusing Under normal operating conditions, the Bose 8.2 speaker system does not require auxiliary overload protection devices. When the fuse is inserted into the fuse- holder, the fusing protection system is complete.
Most failures occur from ELECTRICAL failure caused by applying too much power to the speaker's voice coil. Constant over-powering results in "burned" voice coils. Usually, too low of frequency applied to a small suspension type driver (tweeter/midrange) can physically cause the speaker surround to delaminate.Aug 3, 2000

For instance, if your amp has an internal 20 amp fuse, then you should go for a 25 or 30 amp inline fuse. A fused distribution block will protect multiple amps and other related components.Jan 22, 2021
