Android Head Unit Project
« on: February 20, 2020, 02:30:24 PM »
Hello Everyone,

I have a 2015 CVO Street Glide. I'm working on a project to replace my 6.5 Boom Audio system with a true Android Navigation Head Unit. I'm going this route because I want integrated built-in navigation, TPMS, Volume Adjust by speed, and the ability to integrate any of the various apps from the play store. I do not want to use "Android Auto" interface and depend on my phone.

Integrating an Android head unit to vehicle is a bit of a challenge. You really need to get all the "pieces of the puzzle" set up properly. I did the same upgrade to my Chrysler 300C and after quite some effort I'm pretty happy with the result. I'm using the mounting hardware kit developed for the Sony AX7000 and I've already checked fitment to ensure the new head unit will fit.

All this said, The choice to use an Android Head Unit is not what I'm looking on input for. I need help with audio equipment (Amps etc.) The Head Unit has 2 pre-amp RCA outputs (Front only) and 2X Front and 2X Rear speaker level outputs. I'm replacing both the both front and rear OEM AMPs along with the head unit.  I would like only one single AMP to drive the existing OEM Front and Rear speakers.

Q1.) I'm considering using the [Diamond Audio Micro84U 660 Watt 4 Channel Amplifier] for this project. Are there other amps I should be considering?

Q2.) Should I use the two preamp (RCA outputs) or get a digital interface module to convert speaker level output to pre-amp level input? The Head unit has the ability to adjust fade front / rear / left and right (just like a car) on the speaker output level. But on the two preamp outputs its (left and right only). So I need some way to set the fade between front and rear... Maybe this can be done on the amp itself by adjusting the gain?

Q3.) I'm no audio expert. And I just want a system that will play loud and work well with this new head unit and existing speakers.  I'm looking for suggestions from folks that understand this stuff better than I do.

Best Regards,  Tim

PS: I added a PDF file that shows the Head unit interface I have so far. When this install is complete I'll post a another thread with details on how it works and what exactly it took to do it.

I see by your profile that you are in Cali. and I am by no means the guy to answer your questions BUT give Mike at Biketronics.com a call, he's extremely knowledgeable and helpful and his products should you choose to use them come with lifetime warranty. Plus he is in Idaho a little east of Spokane Wa.

Keep us posted!

So it looks like I'm going to go with a digital processor (Rockford Fosgate DSR1) and a 4X AMP (Diamond Micro84). 

I'm getting both from Tim at www.AmericanHardBag.com

He's a great guy that is very helpful.  Highly recommend.

Now I just need to figure out the plugs for the OEM Amp bypasses.  I'm keeping the stock speakers for now so I need to make some custom connections for the component tweeters.  I'd rather just buy the raw plug used on these amp bypasses and I'd do the wiring myself.  Do not have the part number for the plug yet.

Anyway, Making progress...

I found the plug used for the AMP bypass....  I need to solder in protection Capacitors for the tweeters and frankly the plugs are just jumpers  that bypass the Amp.  I cannot see paying a lot for these bypasses since I need to modify them anyway.  It's just a few jumper wires to solder to the backside of the plug, then seal it up.

FYI Folks...  The plug is listed in the service manual as "23 Place Tyco Ampseal"

The actual plug needed for the jumper is manufactured by TE Connectivity / AMP Brand  Part Number:776228-1.

Datasheet is attached...

Here's some links on where you can get them....

I bought from On-Line Components.  Two plugs for front and rear + Shipping for $20.

1.) On-Line Components https://www.onlinecomponents.com/te-connectivity-amp-brand/7762281-10491971.html?ref=octopartfeed&utm_term=776228-1&utm_source=te.com&utm_medium=referral&utm_campaign=te-disty-stock-check&TEdistID=3104521229MWEB&TETID=1d8raL2GD8 

2.) Digikey https://www.digikey.com/products/en?mpart=776228-1&v=17  *Always a good supplier...

3.) TE Direct https://www.te.com/usa-en/product-776228-1.html?te_bu=Cor&te_type=srch&te_campaign=ggl_usa_cor-ggl-usa-srch-selectmktg-fy20-google-feed_sma-1193_5&elqCampaignId=83716&mkwid=zi51u0HB%7Cpcrid%7C386894952952%7Cpkw%7C%7Cpmt%7C%7Cpdv%7Cc%7Cslid%7C%7Cproductid%7C77

I see that this is an OLD thread but have been looking for someone who is familar with these type of plugs to determine what configuration they leave the different speaker locations in after they are installed in place of the OEM amps.  TRS300 I could use your input if you made any progress using these gizmos.  I would send a PM but I haven't been on the Forum long enough apparently.
