How to install 2 amps and a sub to a factory stereo?

I already have my amps hooked up. Do I take the speaker wires from the amp and splice them with the speaker wires coming from the radio then connect it to the speaker? If not what do I do and how do I connect the amp for the sub to the radio since there is no rca inputs?

You will need to buy a harness adapter from BestBuy or any car stereo store. I believe Scosche is the brand name and they make different harnesses for different cars.

well if you wanna hook up your subs, you will need to do one of two things… 1, if your amp has a high level input, just connect your speaker wires from your stereo to that, or 2, get a line out converter, which you would hook up to your stock stereo speaker wires and it will give you RCA outputs, so you would run RCA’s to your amp.. good luck mail me back if you have more questions

If you want a killer audio system, for your next car, buy a Kia Optima. Infinity 6 speaker, sub, and amp, w/ six disc in-dash changer comes standard on EX models
