Re: alpine iva-d300 problem
Try purchasing a "ground loop isolater", when your head unit and amp are grounded in 2 diffrent locations the diffrence in volatage to ground between the two will cause interference.
Check the below link for more details, can be purchased of a shelf at you local radioshack
Hope this helps

I'm guessing you did not buy this unit new? There should be another cord coming out with an odd shaped plug on the end. This plugs into a required external amplifier that the unit would have included if bought new. You could contact Alpine and find out if they can sell the amplifier separate, or check Ebay and other sites to find one.
I ran across the exact same thing as both of you guys and did a lot of research. I was told by someone very knowledgeable that you have to also change the small DC to DC power supply to match the D300. Its the small 3 inch by aroudn 2.5 inch silver box that is plugged into the back of the unit. Apparently after that it should work. I haven't got one to test with but if you do please post if it works. THanks
Sorry man here's what i pulled from the internet- Crutchfield sells these: Note: The MRA-D550 requires a compatible head unit for
setup and control, it cannot be used without one. The current list of
compatible head units includes (but is not limited to): IVA-D300,
IVA-D310, IVA-D900, IVA-D901, DVA-9860, and DVA-9965.
actually you need a filter on the power supply of the DVD unit since this is what is causing your problem. putting a spike suppressor on your audio in is not a bad idea, but it will kill some of your bass response.
