Im looking at buying this unit from a member on here and I need to know what else I would need to use this as my headunit and everything. Its going in a Dodge Magnum SRT, I have the Kicker system factory with a factory amp for the mids and a aftermarket one for the sub. What do I need to buy to get sound out of it? The factory deck dosent have RCAs im not sure if the audio shop that put in my Kenwood touchscreen put in a amp converter that has RCA's or not. Please let me know what else I would need.
