i have trouble connecting bose system to my aftermarket jl audio 500/1 amp with 10w6v2 sub.

i went to a audio shop today. the guy told me that its very easy to burn the system if i do something wrong, i really wanna do this according to a member posted a diy of adding a sub. now im discouraged... r there anything that i need to aware of when i install it?

what are the wires that i need to splice to the rca cable connects to the amp? do i need the line-out converter or the rca cable(one end wires to the boss hu)?

and last, where can i find this cable(in the pic), i've searched over different shops, but no luck to find it

any replies will be greatlty appretiated!
thanks

oops, nevermind this was in your other thread

 

I have posted the wire colors that you need to tap into. You don't need to buy that device in the picture. Just cut an RCA cable and find the + and - wires for each side, splice them into the OEM Bose harness, and plug the RCA's into your JL amp, which does accept balanced inputs. That's how my JL amp was initially installed.
