Full Audio System upgrade

Hey guys just finished upgrading all the audio components in the 2014 JK. Wanted very clean sound with great bass response. The JK came with the 7 speaker Alpine sound system that has the 8” sub. The goal was to have a somewhat stock appearance. All upgraded speakers where mounted in all oem locations. Here is the list of equipment that was used



Radio - Kenwood excleron DMX905S CarPlay/Android Auto Media Unit



Amplifer - Arc Audio X2 XDi 850.5 5- Channel



Front speakers - Hybrid Audio Unity U61-2v2 6.5” 2 way components



Sound bar - Hybrid Audio Imagine I61 2v2 6.5” Convertible components



Subwoofer - Audiomobile EVO10 in modified Alpine Enclosure



Backup Camera - AIS Jeep Backup Camera ( mounts to spare tire)

Full Audio System upgrade

Removal of the oem headunit was tackled first. This involves In removing the rear support bracket that supports the oem radio for clearance for the new headunit. Minor trimming of the plastic double Din opening to also for clearance.



To retain the oem USB port in the center console, a Pac Audio usb adapter was used at the unconnect module. Was attached between the Kenwood usb and module. The idatalink maestro RR module with the CH1 wireharness to Interface the Kenwood unit to the JK wiring. It also allows oem gauge and information readout to come up on the Kenwood 7” Capacitive Touch screen. With this module, you can retain the Uconnect system if you want, I decided against it since Android Auto/ CarPlay would be used instead.

Starting with the front stage, all wire is wrapped like factory and heat shrink terminated ends. The lower dash boxes were sound Deaden from the inside using matt and polyfill.

Moving onto the Soundbar. Old speakers removed, sound Deadening and fill was added to stop any vibrations. All new wire was ran also with quick disconnects

The wire was routed through new drilled hole. A rubber grommet was used and sealed.

Next was installation and wire run for the backup camera. This camera works if you have a standard oem spare wheel and tire or even larger aftermarket ones. Has adjustable within the bracket.

That is a very clean looking installation. The pictures were very good at showing the important aspects as well. Thanks for taking the time to write that all up.

I'm busy planning my own major overhaul of the radio/amp/speakers/cameras of my 2015 JK and you've given me some ideas that will be real useful.

By the way, what is the RMS output for each channel? And how does it do for filling the cab with sound? I am considering systems at 50w, 70w, and 100w + a powered sub and can't really determine how much I really "need" (I'm not looking to rattle my teeth).

Ken


85w x 4 @ 4ohms 400w x 1 @ 2ohms
125w x 4 @ 2ohms 400w x 1 @ 2ohms.

I would say around 70w a Channel is a good starting point to fill the cabin with good sound. A good efficient sub would need at least 300w do have decent output. But then again, it all comes down to budget.

Next moving on to the amplifier installation and wiring. 16ga Wire was used for the front and rear speaker outputs. The subwoofer output used 14ga wire. Power per channel 85w rms x 4 400w rms x 1. The front stage passive crossovers are mounted under the driver seat and the amplifier under the passenger seat. Both seats were removed to make mounting rack out of PVC sheet.

4ga OFC power wire was ran from the ampli the engine compartment. A mount made from ABS supports the mounting of the fuse holder above the battery.

Last part of the build is the subwoofer enclosure. Decided to modify the oem 8” Apline Enclosure to fit the 10” shallow Audiomobile EVO 10 Subwoofer. Most of the front side of the enclosure was cut away. A new 10” mounting ring and panels piece was routed out of PVC. Then bonded using fiberglass .

The enclosure was then textured coated to blend with the oem plastic material.

The Enclosure was mounting back in the vehicle using same oem mounting points. Was able to keep all oem functions. Audiomobile sub comes with a protective grill also.

Overall sound is so much better then the oem Apline System night and day difference. Has great output and clarity at all volume levels. Zero distortion at full volume. Again, was able to gain all the good thing what an aftermarket system can offer, but still able to retain all the oem features like steering wheel controls and vehicle information on screen. Well worth it for a system like this that can last many years to come. Still everything is hidden and has an oem appearance.

Added another upgrade to protect the headunit Incase when top is off and there is a down pour. Also helps to protect for other elements when off road. Here is the build on the radio dash cover. It was made out of fiberglass and textured for durability. Pops on and off easy. Doesn’t move around while driving also.

Then after several coats of filler and test fit, time to give it a couple coats of primer.

After sanding to a 400 grit finish, time to lay down the texture. Then after drying, then painted a satin black for the finished look.

After a few hours of drying time, I added Alcantara Black suede on the backside for protection of the screen and buttons on the radio.

That cover is awesome. Great job. I bet others would be interested in something like this. I am currently looking at an audio upgrade and this cover would be a very neat addition as well.
