Ok guys i need help...I just installed some new kenwood 6x9's and i'm happy with them but the other day i hooked up my sony 2 channel amp to them and it didnt work and i can't figure out why...the power light on the amp would flash on then turn off when i started my car and the 6x9's wouldn't work and now my 3 way cigarette adapter doesnt work so i must have sent a surge through it but i dont no how cz its no good and I am positive i have everything hooked up so im thinkn its my ground thats no good but i havnt got time to check it lately so ne ideas are great. Thanks

Check your fuses.
Check your ground.
Check your connections.
What do you have the amp hooked up to for power??
