Ok, if there's someone who knows more about audio stuff out there than me (Wich there propably is), I need your help.
When I fried my sub amplifier, I went along for a while without my 12" sub, it needed to dry out anyhow, but yesterday, I decided to hook it up to an aging AKAI stereo amplifier togheter with another (8") sub that is also RMS rated at 150w.
I mounted the sub with magnet out, since I believe that there's still some (not much) moisture in the box, so that it wouldn't take any more severe damage than some dirt on the cone (Rather than rust on the magnet).
Now, today I was playing at about max level for both subs (That old amp has got some juice with 4 OHM speakers!), and the 12" suddently goes silent. I hurry to shut off the amp and check the wiring, wich isn't the best.
The wiring was all good, and I started up the amp again to see if it was just over heating. Both speakers played fine again. Didn't bother more, until the 12" went silent again. I shut off the amplifier and hooked up the 8" to the outlet that had been supporting the 12", and it worked. But when I hooked up the 12" it wouldn't. I opened up the 12" box to check any internal wiring, and it was completely ok. I replaced the connectors, just to be sure, though.
Same procedure; Start amp, play for some time, 12" goes silent, I hook up the 8" to that outlet, it works fine. The 12" only works after the amp has been off for some time.
Neither the amp or the sub are hot in any way, the dust cover (Round thingy in center) of the sub is completely cool, as well as the magnet. The amp is warm, but not hot.
It's a rather old sub (Pioneer TS-301, old revision) from about 2002-2003. I don't think it has any fancy over-power protection, since it's a pretty simple sub without any circuit boards or anything. Not even a magnet cover.
Anyone got any idea of what could be causing this? The amp clearly states "Speakers 3-16OHM" on the back, so I don't think resistance is a problem.

The idea of any hi-fi system is to reproduce the source material as faithfully as possible, and to deliberately add distortion to everything you hear (due to amplifier deficiencies) because it sounds 'nice' is simply not high fidelity. If that is what you want to hear then there is no problem with that, but by adding so much additional material (by way of harmonics and intermodulation) you have a tailored sound system, not a hi-fi. - Rod Elliot, ESP
