Speakers suddenly quit playing

It ma ysound dumb, but did you check the ground? if it isn't a good ground, it may the cause of the amp turning on and off.

try to use your friend's HU and amp, and see if the speakers are still fine.

Well, I checked the ground and when I replaced the fuse in the block and turned on the head unit I blew a fuse on the amp. I will have to check it out again tomorrow after I get another fuse for the amp.

I'm still baffled with one side going out seconds before the other. I don't think I'll feel any sense of relief until I figure out exactly what is wrong.

Thanks for all your help and suggestions everyone.

Something in the amp may have shorted out. How old is the amp?

I tried earlier to look up info on your amp and had very little luck.

I was going to say ground as well Justin, but if the amp is blowing fuses, yeah that's looking to be the problem.
Perhaps when the crossover came unplugged, it shorted and the amplifier was damaged. It's pretty surely the amplifier though, which can be repaired more cheaply than replaced.

The amp is an old one. Can't even find specs anywhere on it. A friend gave it to me and he hadn't used it in years. I took the back plate off, but didn't see anything wrong. I'm going to double-check everything tonight and try to hook it up again.

If it is the amp I don't know if it is worth repairing or not. At least it's not my components, they are worth more than a typical 75 x 2 amp.

The pdf should still be available, at least from Directed if not the web. Here's an interesting thread concerning looking for old PPI manuals and stuff:

http://www.audiobanter.com/q-t_3674-Any ... loads.html

... a simple e-mail to [email protected] will get you a pdf of anything we have
in the archives. There's a lot more material in the archives than was
ever web-linked, too.

...we have a tendency to put stuff like that in our dealer
section, and not the public. With audio being as DIY as it is. that
should probably evolve.

A lot of their stuff can only be accessed through the dealer section. I don't know how much help it'd be, but I'd just email the guys if you want a manual, etc.

The only Sedona stuff I was able to find on the web was the dip settings for my old XO-2. I guess you need "permission" to look at many of their pdf's.

a couple options:

just to isolate the amp as the problem, get a multimeter and check the speakers for resistance, make sure they are/arent blown.

disconnect the speakers and see if the amp turns on. definetly check that ground too.

Well the amp is definitely toast because it keeps blowing fuses and my other amp for my subs runs fine when I use that power source.

I checked my components by hooking up my home stereo and one side plays fine, the other is in question. The tweeter works ok but the 6 1/2 seems to be much quieter. Can a blown speaker still produce music? It smells like an electical fire, so I'm pretty sure it is toast. I guess I'll email Rainbow to see how much a new woofer is. This sucks!!

Anyone have an amp that they're not using?
