sorry I hav't registered yet since I won't have acces to high speed til tomarrow and dial up is to slow. any ways, I have a pretty basic, yet highly sophisticated for a 16 yewar old setup. Im pushing 4 KLH toweres with 12inch woofers all around, aside from a KLH center and sub. out of a pioneer reciever. now my reciever keeps giving me a flashing "overload" message and then it turns off. THis is of course at very loud volumes. I am assuming that this is a heat problem, and no, unlike most people I do not have anything over it, it has about 12inches of free space above it. It looks like some 92mm computer fans would fit tight over the vents to suck hot air out, but I don't even know if heat is the problem. any ideas?
