Can i use a 250v 4a fuse for my cerwin vaga speaker even if its not a slow blow and what could happen if i did would it damage the speakers

channel in receiver might have gone out or did you blow fuse inside speaker - switch to other out put location to see if speaker is issue or receiver

Speaker fuses are rated in Amps. If you cant find the specs on your speaker via google, (I couldn't find anything on the fuse.) start with a 2 Amp 'slow-blow' fuse. That should work at low to medium volumes. If you find it blows at low volumes, move up to a 4 or 5 Amp fuse. E-715 is a big speaker, (handles 400W!) so starting at 2 amps should be pretty safe.

This may not be a fuse. Bose uses devices like this as "speaker protection". If this device is wired to the woofer, that is exactly what it is. For more information, please visit my website at audioserviceclinic.com. Thank you.

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.

Hey
it's a 2.5Amp Slow Blow 2AG fuse..

Most electronics stores stock fuses..also to being a 2AG fuse they are exactly the same as the old auto fuses and thus most auto stores carry them in stock aswell..

but remember.....Fuses blow for a reason
and NEVER put a bigger fuse in!!!. try and find the fault....unless he has just cranked it too much :-)

hope this helps!,ben

There are 2 250v 4a fuses inside the amp. They can blow and
that channel will cut out. Check the fuses.

Should be 2.5 amp SLOW BLOW fuses. Not at home, but mine have a label near the fuse holder showing 2.5. Important to get the slow blow. I get mine at Radio Shack in a multipack (amp underwpowered, blow them often)

Depending on the wattage of the amp to the wattage off the speakers depends on what to use and how to control them..If your speakers are rated for more power than the amp can produce it will blow the fuses just as if the amp is rated for more than the speakers it will blow the fuse..Those type of speakers do need a good supply of power to run and speaker wire size could play an important part of that.If wire supply is to small it will over heat the coil in speakers and also blow the fuse...Look in side of the boxes to see what kind of capacitors they have on the speakers or there size to insure correct for speakers them selves..Also look at all of the wire routling in the amp to insure proper installation..Hope this helps you..Have a great day

250v 1A fuse

It is written on the sub. You can also take it out or look at the spare which is taped to the power cord wall plug. I believe it's T1A 250V fuse
