I found this on another forum early last year, I don't know who posted it: "So I decided to email Sanyo Australia, and got a guy who did a bit of research and passed on my queries to Sanyo (Japan) where the Ford amps were made. They got back to me with the specs for the Model# 14788100 premium sound amp: Standard Output：100W(THD1%@30Hz) Maximum Output：150W(THD10%@30Hz) Number of channel: 1ch Operation Voltage Range：8-16V Power Source: 14.3V DC Negative Ground Speaker Load: 4ohm Operation Temp. Range：-10-55℃ S/N Ratio: 70dB Size[mm]：150(D) x 267(W) x 55(H) Weight：1.6kg " I'm no expert at all, but if the high level inputs on your amp can handle 150W max input (assuming the above info is correct) than you should be able to get away with getting the sub signal after the factory amp. I did this and wired a plug that matches the one on the subwoofer to plug into so I didn't have to cut the factory loom. I'm using an LC6 as a line converter to use low level inputs.

I have an LC6, not the LC6i. Do you have +12v going to the remote on? Are the balance and fader settings on the factory system set to the rear speakers only? May have been left that way after setting it up. Is the level control for the front channels turned up enough? Is the wiring connected between the amp and front speakers? (do the speakers work from the factory headunit when bypassing the LC6i and Amp using the wiring that runs from the amp to the speakers). I've downloaded the manual and I don't think the "connected to main channel" light should light up if you are using the "Main Input" and "Channel 2", as this needs to be turned on by jumpers under the cover, which is turned off from factory. This is a guess as I haven't played with an LC6i yet. I would wire it up with the factory fronts going to "Main Input Speaker Level L+R" and the rears to "Channel 2 Speaker Level L+R". Leave the RCA's unplugged and run the factory system to about 20-24 and turn up the output level dial until the "Maximized light starts to flicker." Sorry if I'm telling you things you've done but it's hard to explain in writing. My money would be on something simple like the balance / fader being turned down at the front only because I've done it myself.
