the other day i blew my amp. i opened it up and the power supply is burnt. i also noticed that this amp has previously been repaired (output stage). it's so big i hate to mess anything up so i called fosgate and they want $550 just to fix what is wrong with it and a 90 day warranty. thats a lot for me. so i called a guy i heard about online and he told me thats it's a gamble because certain parts used in these amps he can't get a hold of, but if he coould repair it it would be 1/2 as much as fosgate. do yall think i should attempt to repair it or what?
