Crappy Guitar Amp, or just wrong speaker for the job...?

[IDSkoT 5,000+ posts]

I have a hand-me-down guitar amp board from a really crappy Crate amp that my brother got with his first guitar back in '01. The speaker was impaled during a move, and stopped working. I replaced it with a crappy Pioneer Coaxial... and it plays... but every now and then after a while of playing, it'll get really distorted and let's say the frequency is 5K, it'll sound like it's doing 10K. It's hard to explain because it doesn't make any sense... point is, I don't know if it's the amp, or me trying to use a full-range speaker as a guitar speaker. I don't know if the coil is built any differently, or the spider / cone is any different, and it's just speaker fatigue or something of the sort. I also used a stock "PREMIUM" Ford speaker out of my car that I had laying around... it did the same thing, but I think it took longer to start.

Any insight?

crate amps blow goats, i HAD a couple way back in the day, unfortunately i paid for them, thought it was a good deal, but i really should have spent another 10 bucks and got something twice as good.

they are big cheap and loud. but if you if you wanna be big and loud you can go a whole new route

probably not stable at 4 ohms if that is what your using and its cheap.

I want to. I'm trying to talk one of my good friends to let me buy his old tube amp for cheap.

It's rated @ 4. That's what the old speaker that came out was.

It is cheap, though. I might wire it up to 8-ohms, though. See how that works out.
