yeah i would definitely get an after market head unit. the wattage rating a stock head unit puts out is crap. you can have amazing door speakers but with a stock head unit it will still sound like crap. the more powerful the head unit, the louder you can turn up and still have clear sound. if you turn that stock head unit up, it will get distorted easily-not because the speakers cant handle it, the stock head unit doesnt have the power. if you want to hear your music clearly with the windows down on the highway, new head unit is the answer.

also it will be way easier in my opinion to install an amp to power your woofers with an after market head unit. just gotta run some RCAs out the back instead of getting the line out converter. and like it has been said before, you can get smooth looking install kits for like 20 bucks.

good luck man.
