    Re: 2014 Accord Sport SQ Build keep_hope_alive

    Before I removed the amplifier IC, I did some bench testing with a test CD that contained pink noise, 500Hz tone, 40Hz tone, and 20Hz tone. Tones were generated in Goldwave and full signal strength.

    I had a speaker connected to the output while taking some readings at low volume, and both worked. Adding the scope didn't generate noise. Doesn't matter now that the amplifier IC is gone, but my original plan was just to tap the pins and not remove the entire IC.

    The bass roll-off still exists, but we have ZERO clipping up till 99% volume. These measurements are at the RCA jacks I installed. Also, the HU volume control worked, a good thing for those wanting to use the stock HU by itself.

    500Hz tone, 39/40 volume, 2V P-P (0.5V/div)


    40Hz tone, 39/40 volume, 0.5V P-P (0.2V/div)


    20Hz tone, 39/40 volume, 0.16V P-P (20mV/div)


    I also measured pink noise at full volume, 1V P-P average with 2V P-P peaks

    Working on the H800 installation, i decided to drop the entire headliner and deaden and stuff it. might as well.





    this much fit in the rear half of the roof cavities






    headliner has some plastic molds that will get foam covering. you can see factory sound absorption pillows (used everywhere)

    it's a large piece to manage solo, but it was firm enough to stay one piece and not fold.

    Re: 2014 Accord Sport SQ Build keep_hope_alive

    Got a lot accomplished this weekend. I pulled the CDA-9887 and removed previous factory integration. I ran new wiring for the Alpine PXA-H800 and RUX-C800 and paired it with an Alpine DVA-9861. Fiber optic, Ai-Net, USB, Mic, and power ran to the back, down the middle. Factory radio front and rear RCA outputs (custom) to the H800 AUX1 and AUX2 RCA inputs.

    Some cool things about this include the ability to retain fader control at the factory radio when using the factory radio as the source. I made a video demonstrating the functionality.
    https://www.youtube.com/watch?v=oxirnpWzRP8

    Around 1:30am i decided to tackle the C800 mounting. I modified the sunglass holder to house the controller while retaining the function of the holder. This allows the controller to hide away and is probably the coolest feature so far.







    the H800 brain is located at the passenger rear and a beauty panel will be made to hide cabling. I'll also make a panel to cover the amps and caps (all with windows to show the components). I'm trying an Alpine 3522S for running rears (custom located in the rear seats). I have some extra cabling here and there for flexibility









    a few photos of the wire routing, everything is in split loom. ties or aluminum foil tape at regular intervals as needed. all factory panels fit perfectly.

    Great looking build I'm using Hertz stuff as well but I need to order replacement tweeters. Your install looks nice and clean!

    Re: 2014 Accord Sport SQ Build keep_hope_alive

    Ran an RTA prior to any EQ or tuning effort. Consider it a baseline. Mic in front of my face. Used a Casella CEL-633C.

    This compares the factory HU as a source vs. The 9861 as the source. Factory bass roll-off is seen. There is a 20Hz subsonic filter.


    This compares two different volume levels with the 9861.

    I really like the beauty panels it looks so clean. I wish my amps were small enough to do that with. I rolling in a small hatchback so not much room either. You get so much farther in the electronics side then I can. Really cool to see.

    Learned a lot this weekend. Hoping to be part of the team to help bring SQ competitions back to the upper midwest.

    I also have a better understanding on what I need to improve on in the Accord. Time well spent, and with great people.

    Good I'm in the upper midwest we need good quality systems that you always bring to the table. I love seeing any build log you've worked on people nut-hug brands, but if I had a choice I'd nut-hug KHA above anything car audio.

    thank you for the complements. There are many installers that are better than i am and my ideas are meant to inspire and for others to take to the next level.

    i'll let you know when we get some SQ shows going.
