Can i use another 4a 250v fuse for my cerwin vega LS12 if its not a (slow blow) ,and what would be the outcome
Fuses have different blow characteristics. Such to protect components differently. An extremely fast fuse would protect sensitive components like tweeters and slower fuse will allow transcients to pass and blow on long time fault. If you put a slow blow in place of fast blow, it won't blow as quickly, but it could allow the protected device to be damaged. In reverse, you put a fast blow in place of slow blow, it will blow at normal transcients and be a nuscience to always replace.
You can cross to a fuse of different manufacturer. The reliable manufacturers will have detailed datasheet and subsitute or similar fuse to the fuse you are looking for.
