Adding just a all in 1 sub amp under my seat. I don't know what wires on the back of the stock stereo to tie in the high level speaker out on the amp. (stock stereo doesnt have rca's) also what wire on the stock harness do I tie in the remote wire too??? Please help, Cantor find any wire diagrams online.

 

Year of car?

Type of radio. Built-in amp or remote?

Is the amp designed to tap into speaker output or pre-amp?

Remote?

 

you will have to get a LOC (Line Output Converter) to tap your wires to add an amp and sub. 2 wires connect to positive and 2 wires to negative of speakers then a battery wire, ground, signal. then rca's into rca then hook your amp up. then your sub to amp. Please do it right and check the ohms of sub and amp. If an amp runs 1000 watts at 4 ohm and the sub is a single voice coil 4 ohm its pretty simple anything else just ask or google. plenty of wiring info on google images.
