Audio Systems: amp installation, level inputs, thanks in advance

Question

ch650 gooday, i have a 2006-2007 model civic ex without the navigation and i recently got a boss ch650 model amp which has high level inputs that i could use to hook to my factory system
I was wondering do i need a special connector to attach to the amp cause i am seeing the connection on the amp having 5 pins and i don't have that said connector
any advice would be appreciated, thanks in advance
regards
Gary

don't use that retur it  get your money back or get a better amplifie,
there is a problem on some EX, there is a factory amplifier, that needs to be remove
