woofer component hiss

[91XR-7sled]

I decided to amp my components individually, ex. 1st channel left tweeter, 2nd channel right tweeter, 3rd channel left woofer, 4th channel right woofer. In order for me to do this i had to bypass my crossover. The system sounded real good, loud and clear. Then i began to play with the gain setting on my amp, my tweeters blew up, just stopped working. My woofers still work. I just ordered a new set of tweeters and seperate crossovers, so when they come in i can wire my system the way i want without blowing them again. Right now i just have my woofers hooked up to the amp and running through its original crossover. When i turn the volume up, i hear a hissing sound from the woofers when it plays a certain frequency. Does this mean they are blown as well or is it a wiring mistake or does the crossover on the amp need to be properly set? Thanks for your help!

By the way these are the MB Quart discus 216 component set.

No one can help me with any suggestions?

They also make a clapping noise when they recieve alot of bass.

I sealed the enclosure, it reduced the clapping but they still clap.

please help me

Set the hipass on the amp for 60-70 Hz. That'll reduce the bass going to them and let them take more power. And make sure you have the gain on your amp set correctly.. clipped amp output can sound pretty nasty.
