hey guys, Happy new year!
This is the last build we will do this year, just finished it last night, so...one more build log to hold you over until after CES
The car was our first new gen accord and the goals were:
1. to obtain a decent level of sound quality that is superior to the previously installed aftermarket system.
2. to maintain a stealthy appearance in the interior
3. maintain as much usable space and stealthiness as possible in the trunk, retaining the spare tire.
before all that, i forgot to thank a few people for their help:
[email protected] for his support on the 360.3
Papasin for his insight into his experience working with his oem honda system and various processors which ultimately led me to this decision
Jesse and Jay @drive customers for giving me their wiring color code and other hints since they just built a new accord sema car
Perhaps the main challenge with these newer generation accords is the stock signal source, which as of now, cannot be changed out. The OEM pre-amp signal is the odd mixture of balanced and very WEAK signal, and it is pretty easy to have noise issues and or noise floor problems....as some of our members have noticed...we came up with a solution for it and it turned out pretty good
our man Jesse did most of the work on the interior, while i focused on wiring and the sub enclosure, and Joey did the amp rack and under hood, truly a team effort
lets start first with the fuse holder under the hood. Joey tacked on a metal bar across the oem hold down to secure a single mosconi ANL fuse holder. here is the finished product and two quick pics during the build process:
for OEM interface and processing, we chose the rockford fosgate 360.3, a few people have had strange noise issues with the mosconi processor and the oem honda premium system, so we decided to go the safe route, but additionally, the RF units small dual knob controller really helps in this situation, it provides a easy to reach knob that controls master volume, subwoofer volume, and pre-set controlls. The controller is mounted below his storage pocket within easy reach:
the unit's bracket was bolted through the oem plastic, a grommet installed and cable lead through, and then the factory piece secured back in:
the front stage consists of an illusion audio carbon C6 two way component set installed in the factory locations. Jesse took apart the oem tweeter cup, trimmed it out slowly until the illusion tweeter can snap in and the oem ring can still snap in as well. here is the finished result:
Jesse then ran two pairs of speaker wires into each door, match routed two spacer baffles, bolted them in place and trimmed out the factory metal to enable the fitment of the illusion drivers:
these baffles were then coated with several layers of truck bedliner to protect them against the elements:
then rest of the door is then sound proofed with a combination of STP foam and CLD damper, and the spacer ring secured via factory mounting points:
the Illusion C6 midbass was then wired up and installed:
the same procedure was then repeated on the passenger side:
next comes a series of pics showing the wiring bundles as they travel from the front to the back of the car, ziptied to the factory loom every few inches. down the driver side went the power cable and speaker wires, while the passenger side received the RCAs speakers and remote turn on cable.
to make sure we have enough voltage to eliminate any unwanted noise issues, i went with a pair of Arc audio ALD balanced line drivers to boost the signal. these are tucked away in the passenger side kick panel and they woked GREAT! a lot of clean voltage with no noise and a pretty low noise floor. infact, it is my opinion that with this higher voltage from the ALD, the mosconi processors should not have issues with noise either.
the rear deck was removed and the metal covered with 50 percent CLD damper, and the deck lid got a lot of attention from STP foam damper. the oem rear sub was already removed and we took out the aftermarket coaxials as well for better response into the cabin:
the wiring bundle then continue into the trunk to their respective staging points
