I've been wanting to upgrade my sound system in my WJ lately such as better door speakers, subwoofer etc. I already have a pioneer deh-11e head unit, 50w x 4, and I'd like to just upgrade the infinity amp to a higher wattage amp, instead of having 2 amps, because i'd like to save space. So what i'd like to do is buy a higher wattage amp to power ALL speakers and ALL electrical things the stock amp powers.

Possible? No? Thanks for the input
