Default Audio Control LC7 doesnt Power On...?

Sup Everyone,

I own a 06 Accord Ex-L with Navigation. I'm having problems with my audio system which consist of the following;

*Factory Radio Navigation Head Unit
*USA*Spec PA15-HON2 (Ipod adapter)
*Audio Control LC7 (Audio Line Output Converter)
*Alphasonik PMZ12005A (5-Channel Amp)
*Polk Audio Speakers (Tweets, Quarters and 6x9's)
*Kicker Solo Baric 12" (ported) Subwoofer

I've had this system set up for nearly three years. However, yesterday i noticed some static coming off my left speaker, while trying to diagnose the problem i accidently allowed the "remote in" and the "+12 volt" wires on the LC7 to make contact. Since then the LC7 has been unable to power on. Hence, I get no audio sound. I checked the radio fuse thinking perhaps it may have blown but the fuse is good. Additionally, the radio is able to power on/off, change stations etc but there is no sound.

I dont believe the LC7 has a fuse so i am uncertain if the issue is with the radio, amp, or LC7. Can anyone offer some assistance with this? I'd greatly appreciate it.

Thanks in advance

The turn on lead and the 12 volt lead should not have caused the problem your describing, unless you did this while it was connected to your HU in that case the problem might be inside your HU and its turn on lead. Could you possibly be mistaken as to which leads got crossed??

As I recall most of these AC products use a very simple DC to DC convertor inside, but don't rule out that they might have protected the device with a internal fuse, or a pico fuse < these are green and as small as a 1/4 watt resistor but with a current rating clearly stamped on the body>.

After carefully rechecking the wires I noticed I accidentally crossed the remote in with the +12v. Once connected correctly everything turned on fine.
