I had the D3 installed a year or so ago and I am very unhappy with the sound, I have alpine door speakers, had alpine in the back went back with the stock , I have an amp and sub but the sound is terrible. I am about to go back to stock but I hate that I dumped all the money into this just to go back to stock.Any suggestions for something to make the sound better ?maybe better speakers or what???Always thought my stock unit sounded great but wanted the Nav system and the Ipod touch screen is great on the D3

 

imo its something with ur install or settings

 

I am think ing the same , I have played with the settings and seem to do more harm than good , I hate it .

 

You mentioned an ipod. Does EVERYTHING sound like crap on the D3, or just the ipod? If it's just the ipod it's probably the EQ settings on it. If it's everything, read on...

I have a D3 and was using the stock amp/speakers until last weekend. After installing my real amp/speakers/sub I had to seriously mess with the settings on the D3 to get it to sound right.

I started by making sure my amp crossovers were passing through as much signal as possible while still being turned on.

On the HU, start by turning off the high pass filter and making sure the sub output is on and set at the highest setting (125 I think).

Put the EQ on flat or something mild. Go to the staging screen and switch between them all. There should be an obvious difference for each one. I thought the second one from the left was the most 'robust' (theatre ?).

Go back to the HPF and sub controls to dial in the signals going to each speaker set, then tweek the EQ to your taste.

Between doing all of that, setting the gains and crossovers on the amp, and figuring out that a normal 1' ethernet cable CAN'T be used in place of the 20' cord that was supplied with my sub remote control ****, I spent about two hours in my driveway on Sunday afternoon with the car running. I think my neighbors were even starting to worry, or maybe they were just PO'd about all of the noise my new stereo was making on top of the usual racket that my exhaust makes

 

I will mess with it some , but about ready to pull it ,sell it and go back to stock .

 

Go to your local mall and find a ricer with a sub so loud their license plate frame is buzzing and offer him $20 to set up your system for you

Really, ask around to see if you can find a somewhat trustworthy late-teens/early-twenties kid with an amp in their car. you might have to put up with some attitude for a few minutes, but it will probably sound good when their done.

 

Update , a guy from work looked at my system, made some adjustments and its kicking some nice tunage! Not only that he is looking to buy him self a vette!

 

Sweet. Once you catch the vette bug it is definitely hard to shake

 

My amp is mounted to the back of my hatch area and grounded to the bolt in the center console , is there a better place? I seem to be losing ground as the amp light will start flashing and the sub cuts out. I cleaned up the area and ran wire from the ground wire so that its now on both bolts and hoping that will fix it but wont now until I get some time in it ?After this guy adjusted everything the sound difference is amazing.

 

That is a bad place to ground, go to a seatbolt or even better remove the side pillar which covers the seat belt mechanism and there is an oem ground there you can use

 

THANKS!

 

It cut out again on the way home , I have moved the ground to the oem ground by the seatbelt, I hope this fixes the problem and there ist something wrong with the amp.....
