Time and I are preparing to install a Mark2 into my 2000 Saturn LW2 (wagon) this weekend.

Our current plan is to purchase a new head unit (CD/AM/FM) which has AUX-in, and replace the factory stereo with it. Then install the empeg in the empty [amost-DIN sized) slot below it with a little careful cutting.

I am not particularly concerned about the specs on the new head unit, other than cheapish, i.e. under $200. Any recommendations?

Additionally, I read a post about Saturn's suffering from a 'negative spike' issue, and requiring a diode; Any details?. I assume it's attached inline with the power. Any special requirements for the diode?

Any other tips for this install would be appreciated.

Thanks,
