Get a real amp, stock sucks. No matter what it came out of. Compared to aftermarket. Most stock crap uses IC chips in their amps which will only put out 12.5 watts, no matter what they are rated. Mosfet amps put out more. Remember that auto makers want to keep everything cheap to make.
Get like a soundstream, autotech, zapco or something like it if you want real power. I have not looked into the monsoon systems, but stock is stock. and who wants stock? stock speakers are rated at 10 ohms so a good amp will only put out 0.4 of the rating they have being that they are rated at 4 ohms. just some info for ya'
