So I'm not sure if my post should go here or in the Technical side; but I'm hoping to get some help with this head unit. I gutted my 2012 Shaker system and put an all aftermarket system with the DEX-P99RS at the heart of it. I've also installed (4) Polk MM 5x7s in the front and rear; along with the Shelby/Kicker 8" component subs and 2 12" Alpine Type Rs in a Mustang specific sealed enclosure. The speakers are all powered by a JL Audio 6 channel @ 100 W/2 Ohms and a Brutus 1700 W mono block pushing the subs. The big question here is (don't mock me going to Best Buy to have it all installed), but, I think the whole 31 band EQ intimidated the installers and the NW/EQ is all 'flat'. There's no major adjustments to any of the speakers; so, it sounds VERY clear and full of treble. Bottom line is; it's not sounding like a BRAND NEW system should sound. I don't want to go back to Best Buy if I'm going to be sitting there for HOURS while they figure it out. Is running the Auto TA/EQ going to adequate for getting some "depth" and "character" to the system? Or do I really need to get in there and manually tune EVERYTHING? Does someone maybe have a "rock" and "rap" EQ template I could use? Any help would be great!

 

so many variables in the car that you aren't going to find a truly good template for your car. your specific car has a unique environment with your setup than anyone elses.

the auto-tune is quite good on the unit and will definitely get you a big chunk of the processing done.

however, you bought a unit with all of those capabilities, so use them!
after using the auto-tune, dial it into your personal tastes.
it will take weeks of fiddling probably before you get it perfectly how you like it.

 

I would suggest finding a shop in your area that has an RTA to tune your car properly. You can always "tweak" it from there, but seeing where things need to be in your environment is a massive advantage.

 

I did run Auto TA and EQ on my unit. After that I spent few weeks listening and being not satisfied with the sound. Did some manual tweaks, but still not good.
In the end I spent some time turning off all DSP features (and I mean ALL: flat EQ, no TA, crossovers on "flat", no loudness, etc.). Now I am mostly happy with my sound. I know that TA gives me much better stage, but it makes sound somewhat "unnatural" to me (not sure what exactly this means).
I know, I feel kind of silly: paying all these money for unit with all these features, and turning them all off in the end.
But I never trusted those DSP's, and I guess I never will.

Now I have related question: I'm looking for a head-unit for my other car.
I found this JVC "900" series: double-din KW-R900BT, or single-din KD-R900.
In specs it says TI/Burr-Brown 24 bit DAC, 5V pre-out. Plays WAV files from USB storage (still no FLAC ).
To me - this is all I need. If I set everything to "flat" again - do you think sound quality would be on par with p99rs?
Anybody had any experience with these units?
(priced very reasonable at $200-300).

Thanks
