rednug Dang dude, that's awesome. Congrats!

pocket5s I know most aren't into the audio thing like I am, but this past weekend was nationals. Despite a few issues during the weekend, Veronica did pretty well.

Runner up INAC Amateur
5th place MECA MODEX
2nd place IASCA 3x







With the season over, I'm going to focus on getting the install cleaned up, then next spring or so I'll fix the rear quarter panel damage done last winter, respray it and hit some car shows along with audio shows next summer.

Well... it's been up and down lol. I started a redo on the trunk and it has not gone well. I just got it playing again last night finally after a lot of hacking and testing. So, it will be playing for nationals (October 12th & 13th in Nashville), then it's getting redone, yet again. Going to do something far more simple and less ambitious.

The volume control via arduino is done and works awesome. I just need to find a nice way to mount the two electronics boards so they are tidy and neat. The first and main one is in the pics. The second is a smaller piece that is a DC to DC converter, to step down the 12v to 5 volts that the arduino needs.

That will consume most of my offseason with it (i.e. this winter). I'll keep my current amps, but they will reside most likely in the spare tire well now. I might, maybe, change up the sub as well, but I'll have to see.

ObnoXious392 I was giving my two cents but thanks for your concerned correction.

Nice project btw.........

pocket5s A few more updates. been a while

After the big show in texas, I started working on a few things. One of those is redoing the trunk setup. The amps will have the same positioning, but will be mounted different.

Here is a pic of the panel that will go in front of the amp. The plexi (mentioned earlier in the build) is inset into the panel.



I've a few items for it as well. Another fuse block, a pair of linear actuators and a pair of fans. Lots of goodies

on the cool techie stuff...

I mentioned in the post above about the arduino. Well, I finally got around to working out the piece that communicates with the Rane DSP. The Rane has an input that allows it to accept a 0-5 volt signal and from that signal you can tell the rane to control levels (i.e. volume). So far so good.

However, the arduino does not output voltage, it outputs a digital PWM signal. Internet to the rescue... I spent 51 cents and bought a capacitor and a resistor that will take that PWM signal and basically convert it into the required 0-5v output.

The video below shows this process. As a test, I hooked a spare Rane DSP I have to the computer and brought up the program that controls it. In the video the small window on the right shows the current volume of the rane. The big white window on the left shows an output console from the arduino.

What I did for the test was have the arduino loop through the PWM signal range, basically simulating going from volume level 0 to 38 (the max volume from the head unit). As it loops and sets each volume you can see the rane's volume increasing.

Here is the arduino and the rane all connected up to my makeshift "workbench". The spare rane is the piece on the floor with the "00" being displayed. The yellow cable is a cat5 cable connecting the computer to the rane.



Here is a closeup of the arduino with the capacitor and resistor in place along with some test cables. I used the DMM initially to test the voltage before hooking it up to the rane itself.



So... what does all that mean? Well it means that I can combine the code for capturing the CANBUS volume signals and combine it with this new code and have the factory head unit's volume control the rane via the arduino. simple right

I hope to have all this in place this coming week. Just need to run some wires for the canbus signals in the car, hook up the arduino to a power supply and a few other odds and ends.

Sorry to break it to you, but blanket statement like that are complete nonsense.

I completely didn't see this, sorry there several 3.5's that will drop on to the factory dash locations if that's what you are looking for. The 6x9's on the doors are fine, and work as nice midbass speakers.

Two 12's in a proper enclosure will be quite nice. Any particular subs?
