2003 MiniCooperS Sound System Upgrade
 

I bought this car used. Sound system stank, which I assume was the stock model. I swapped out the head for an Alpine CDE-123 so I could get Sonos and improve the sound. Turns out that I need to upgrade the Sonos tuner to their sxv200 which is on the way. I thought that I would add a small amp while I was at it. I'll see how the sound is then, and, if necessary, do some speaker work. I don't want to spend much money as he car is 11 years old with 81k miles.

I'm looking for amp suggestions that would bring the system from crap to ok. Truth is that my wife drives the car and she'll be fine with ok.

Thanks,

Ken
