How can you hook up another amp to your sub amp for your 6x9?

Answer 1

you cant a sub amp is mono im assuming yours is ,you didnt give any specs.youll need an additional amp stereo amp and you will need a set of RCA outs from your deck. if you only have one set of rca outs you will have to get 2 y rca adapters and split the channel one set to sub amp other to stereo amp..if its a sub mono block amp it does not put out stereo sound. thats why you have to split it from the head unit heres a link to show what they are
