I am looking to build a very basic set-up in my Escape. I want a simple front stage (6.5" components) and my existing altered MACH sub box with an eU-700.

I was wondering if anyone has any experience with the ARC KS125.4 with an OEM HU? According to ARC, OEM integration is simplified by way of the following:

ARC Audio KS 125.4 Mini
The KS 125.4 mini uses a Patent Pending Auto Sense Turn-on circuit that offers a significant improvement in reliability. No more will the amp unexpectedly turn off in the middle on a song. Instead of relaying on the music to supply enough signal to turn the amplifier on ARC Audio’s new design detects the BTL IC (chip amp) used in the vast majority of stock head units and amplifiers. To further simplify OEM integration the KS 125.4 uses a fully balanced input stage that is switchblade between speaker and RCA input. Simply plugging your stock speaker wires into the RCAs will supply perfectly clean signal and turn the amp on. What could be easier then that? Well how about reversing the remote turn-on connection to turn on the rest of you amplifiers? Once the KS125.4 is set to Auto Sense the remote turn-on now becomes an output to turn on all your other equipment.

Mainly wondering because this install has to be super stealth due to going to DC on a regular basis and already having one HU stolen. The Stock 6 disc changer is back in and decent enough. The ARC is perfect for fitting under the passenger seat without being able to be seen. Modified MACH box takes care of the rest.

Any help would be appreciated. Thanks
