I'm looking for a list of recommended equipment and some basic install tips for dummies. I have some older experience doing speakers/amps/subs/wiring all that but newer cars are newer beasts.

What are the pros/cons/necessitees in order to install a sub/amp kit with the factory radio.

Thanks for the inputs!

Car stereo's are always low-voltage wiring, so if you have prior experience, it should be a snap. The only time I'd get nervous would be if you plan to do anything radical, and even then, just follow best practices, and you'll be fine.. A standard speaker swap-out & amp + sub addition should be no problem.

As far as brands/product lines go:

Rockford Fosgate 3-way (Doors)
JBL GTO 2-way (Dash)
Skar Audio (DVC Sub)

These should be plenty.

If you plan to use the stock head unit, and only amp the sub, make sure your impedance values match up, the front doors and dash speakers are wired in parallel, and the impedance value shouldn't go below 1.7 ohms, or you'll need to bias rearwards to prevent burnout. Rear impedance values shouldn't drop below 2 ohms.

If you plan to control, everything off the amp, dealer's choice.

Is there a step by step someone has that can help me wire an amp to the factory radio. I really only care about the signal wires to line Output Converter bit. Where do I tap the signal wires for the LC2i and what should I look out for? Thanks!

Know it’s been a while, was checking to see if you ever figured it out? Ima having problems with the subwoofer not coming on. If you got yours going , did you run into any problems?

THe easiest way to do this is go get an LC2i from crutchfield, an amp install kit, amp, aftermarket sub. crutchfield will give you a free KIA OPTIMA install instructions on wiring. You will basically disconnect, or cut and splice the wiring going to the sub on the rear deck and run It to the LC2i. You’ll get RCA outputs in return from the LC2i, then you run that to your amp. If you’re looking to do an easier version of this, I got a kicker hideaway that I ran in parallel by splicing into the signal to the rear deck speaker and put in under the driver seat. I kept the factory deck and replaced all the door speakers with focal 2-way speakers. all of which you can find install and wiring by buying something From crutchfield and they’ll throw it in the package for you.
