Speakers were a gift from a friend so I can't complain
.
Noticed that on certain sounds I'd get a crackling - usually louder sounds.
Fed it audio from Audacity at 440Hz and measured the output on my scope (with it driving the speakers)... sure enough it's got about 2Vp-p of 100Hz on it, and can also hear this weird "warbling" effect.
So either it's bad caps or just insufficient from the start. Need to crack them open to upgrade the amplifier anyway, it clips at around 7Vp-p to the speakers...
