the amp could have gone into thermal protection, or have a overload protection. It would blow the fuse if it is constantly being abused, and the woofers your driving are a lower impedence than the amp is rated to handle, it would attempt to put out more power, and would likely blow the internal fuse, due to the fuses most people put along the transmission line being way overrated…
Yes, they can. It depends on the design, but most car amps rely heavily on the capacitance in order to keep them in check. theyre very crude, and without the capacitors working the way they should, they can go into a oscillation, and essentially blow themselves up. Most components are rated at 50,000 hours, wich is about 6 years continuously on. If you were abusing the amp, it very well could extremely decrease the life. And im sure the components used were about a year old or more by the time he bought the amp. But, something could have come loose, or low voltage could have damaged the amp. And its only a 300w amp, so im sure it was constantly clipping wich is the main cause of amps blowing up.
if it was installed buy best buy im sure it wasnt clipping. most of the people there are retarded but they know how to set a gain on an amp so that it doesnt come back for warranty.
Unfortunately, that is not quite so true also… There is. If a sub were to loose a coil, it would run at a higher impedence, and the amp wouldnt be able to put out as much power. If a sub is abused for a while, the coating around the wire used for the voice coil can crack, or get burned off from heat, or rubbing. If this happens, the sub would appear fine, but every once in a while it would short, and if the amp dosent have short portection, it would blow the fuse. sure as shit souds like a blown fuckin sub to me :gotme:
you really ahve no clue what you are talking about do you? you copied exactly what i said in my post and replied to speedped with it and then told me i was wrong at the end of your post. tell me, if i have dual one ohm coils and i wire them in series to a 2 ohm load and i lose one of those coils, what would my final load end up being?
