Blown speakers

Systems

I must have the worst luck about speakers ever! First My cheap amp blows so i buy some brand new rockford fosgate power amps.(250.2 and a 500bd) Then i got the wrong box for my momo 12'.(qlogic) so i've ordered the subzone box, now my power 250.2 messed up some how on one channel and blew my momo components. so i had to put my STOCK SPEAKERS back in. i'm sending the 250.2 back to the company and i was wondering if you could help me fix my components. i have the credit report, but i got them from ebay brand new yet on the report all it says is something about ebay. Did i pay all that money for no reason or can you guys save a guys pride and joy and help me out. I still haven't got my system sounding good because something always messes up. I can't stand my friends(and everyone else) laughing at me because i spent all that money and there stock speakers are doing better.
