Pretty much that RAV DVD 2 should have 5 or 6 preouts on it that u run to amps and then speakers, or just line outs that u run to speakers.
That will give you the Digital surround sound.
Speakers are speakers, no such thing as digital speakers.
It sounds awesome in a car and I vow to do it one day, just don’t no when that will be.

Yes it is loud, but you don’t have to play it loud, just I like to do that.
If ya want to save room, a decent 8" or 10" in the parcel shelf is always an option.
