so i go to gc, and buy a new svt 4x10 hlf. i come home and i hook up my cheapey 100watts head (i was going to use it till i got a power amp iam switching to a preamp power amp setup).well i didnt even play for 10 mins and i blew the fuse, i replaced it and when i tuned it on and it would do is make a werid sound threw the speakers. i tried two cabs and two differnt cables. no luck, my dad is bring the head to get fixed if it can, well i wanted to see if my cab was messed up so i got my little fender pratice amp, it has a ext speaker jack so i plug my cab in to that.well i ended up blowing up the fender amp after like 15 mins. from every thing i have red on this site they say u cant hurt a cAb or head by sending not enough power to a cab. i didnt even have the volume pass 9 o clock 2 or 3 ish. do u guys think there some thing wroung with my cab or i was just dumb for trying to use wat i did as a head.
