Hey, I can't decide which alpine to get, 9847 or 9835. I only like these two models because they are black, which looks the best in my car. However, I don't know if I will tell much of a sound different between the two units even though the 9835 is a lot more expensive. The 9847 doesn't have any band parametric EQs. Is there much sound difference? I have stock speakers and a w6v2. thanks.
