Replacing with aftermarket, you have to:
Run new power wire from the battery, which isn't bad if you're comfortable removing interior panels
Extend the audio signal in/speaker signal out wires from the bose amp harness to reach the new amp, which isn't bad if you're comfortable using a soldering iron.
Mount the amp somewhere, again, not bad if you're comfortable with a saw, drill and some MDF.

The other important factor, is if you're still using the bose headunit, you need an amplifier that is designed to use balanced audio inputs. JL Audio amps all do, and are easy to find. Other brands have select amps that do, but they're generally harder to find.

Kappas sound good in noisy cars where their bright tweeters overcome the wind and roadnoise. In a decent car, they sound too shrill.

Massives will be the loudest. The tweets are very in your face sounding, but not shrill like infinity's. Midbass is phenomenal, and they love tons of power.

Hertz are more laid back sounding. Tweets are warm, midbass is average, midrange is nice and smooth.

JBL's are a lil smoother than the hertz, but the tweets are lil more sparkly. Midbass is above average.
