Message They are typically power overrated and not of great quality... the difference between a decent external amp and the HU amp is very noticeable in audio quality. Your speakers work better when driven at a nominal higher rate that an external amp can provide.

You also want to add a sub, which will need to be driven with a D class amp to be effective, which means a battery power wiring kit, which you'll need for an amp anyway, so I just went that route.

When I replaced all the Bose audio in my Silver Zed, I went with a digital 5 channel amp from Diamond Audio that has a small footprint and mounted nicely under the passenger seat:

Diamond Audio Micro 5V2

Also with an external amp you can trim your outputs to the speaker, set your x-over and balance your volumes to your output channels. Yes, you can also do that with DSPs in the headunit, but every time you pop the battery cable you have to go through and reset everything.
