My Ride: 2003 M3 Vert
Dynavin: Do I need a signal processor?

I am in the process of upgrading my sound system in my 2003 M3 vert which now currently sounds like crap. My car came with a single DIN Kenwood installed, and I hated the way it looked and worked, so I replaced it with a Dynavin (the most current one the D99+).

And now I have purchased the following to replace my current speakers:

Boston Acoustics Pro60 SE
http://www.amazon.com/gp/product/B00...ls_o02_s00_i00

JL 8W7 (making a small sealed box that will fire into the ski pass)
http://www.amazon.com/gp/product/B00...ls_o03_s00_i00

Alpine PDX-V9 5 Channel (100x4, 500x1)
http://www.amazon.com/gp/product/B00...ls_o04_s00_i00

Ok, I have a couple of questions but the first one being is:

1.) I have read about the outputs of the Dynavin are not very good, am I going to need a signal processor? I obviously want the cleanest sound possible, but this is a vert, I know it is not going to best sounding system. I know the Audison Bit One is highly recommended, but I really can't afford that now, not to mention it costs about half of what I spent already. Should I be ok with one of these:

AudioControl Matrix Plus:
http://www.amazon.com/Matrix-Plus-Wh...ol+line+driver

or maybe step up to this so I have EQ controls?
AudioControl EQS
http://www.amazon.com/AudioControl-E...diocontrol+eqs

Or should I just try it without one and see how it goes?

2.) From what I am reading, it is better to go with the active crossovers in the amp vs. using the crossovers that came with the speakers. I know I can setup the Alpine in a bandpass configuration (I will not have any rear fill), can you tell me what I should be setting my crossover points to?

3.) Last question is in regards to the installation of the front midbass drivers. I do plan to cut the door because from what I read that is the only way to get good midbass out of the speakers. Is it really worth making a baffle to mount them to the door itself or can I get by with mounting the to the door panel, as in here:

The Dynavin has simple audio controls, similar to stock. You dont NEED a processor but if you WANT more adjustability, EQ, time alignment, active crossovers, etc... by all means run a processor. Ive run processors or EQs in my personal cars....well...always. I currently run a JBL MS-8....similar (kind of) to the Audison Bit One you mentioned. The EQS would be a decent way to go for adding EQ and bumping up the voltage. If you know what you are doing and you have a good ear, a processor is an awesome way to go.

Crossover point is going to be totally dependent on the speaker set you are using.....I dont know where those speakers crossover but most components crossover between mids and tweeters in the 3K range. If it were me though....id probably just use the crossovers that came with the speaker set, Boston knows what they are doing....

Just like everyone else, I fought to get any midbass in the door of my E46 with little success until I cut the door behind the speaker....make a nice baffle, cut the panel, and save yourself the time of having to do it over.

I second what Jeff had to say. You are putting a lot of money into this setup. The Dynavin's EQ functions are really very basic. You would be cheating yourself in a way if you don't add the processor since you will not really be taking advantage of what your equipment can really do.

Thanks for the replies, I have built the box for my JL 8W7 and I temporary hooked up my amp and I had to turn the gain to the max setting to get bass out of it. So I just ordered the AudioControl EQS and hopefully this will help.

After more research, I agree in just running the components passive. Also will bite the bullet and cut the doors and make baffles. Not really looking forward to it. Biggest concern is being able to line up the baffles with the door panel.
