I kow that I've asked some of these questions before, but a few ideas came to my head this morning since I'm not satisfied with the results.

Equipment:

10" AA Arsenal Sealed enclosure

Factory Headunit

1 Stinger LOC

1 ZED Minilith

Here's the deal. Everything is connected well. I have a good ground, wires, and RCA's. The sub is getting a bit of a warble sound to it a low volumes (I'm sure it is still there when the volume is up,but the music is covering it up). In order for me to get any output in this sucker, the gain has to be almost all the way up and I don't like that. Something is wrong. Here is what I've been thinking...

I really think that a four channel LOC would be fix for the overall problem with output and noise. Something like an Audio Control and others offer. Zed has a very specific way of connecting his MINI to a system using four inputs to get full signal(6db loss for each input not connected). I have all four channels hooked up by splitting the signal on the left and right outputs on the LOC.

Here is why I think I might need a better LOC (or at least one with more channels).I tried using my sub out on my truck and splitting the signal to have four inputs into the MINI. I did NOT get the same full strength signal as I did using the Front and Rear RCA's. This leads me to think that this might be the problem with my friend's install (not a strong enough signal maybe) Do you think adding a four or six channel LOC may be the solution? An aftermarket unit is not an option for this install. Thanks for the help. Sorry it's so long.

Still needing some help guys. Anyone have any idea if my theory is correct. Thanks.

This sounds like a similar problem I had in my 04 Ford Crown Vic. I had a decent stock HU and steering wheel controls that I wanted to retain.

I picked up a SCOSCHE LOC and wired it up behind my HU and ran a set of RCAs to my amp in the rear (MTX 342). The LOC had outputs for 2 sets of RCAs but I only used one set. I had to turn the gain on the Mtx almost all the way up to get any decent output out of my mids and high as well as crank the HU almost all the way up.

The amps tended to overheat because the gains were so high, but it was the only way to get any real sound from it. Those MTX Thunder series amp tended to like a higher voltage signal through the RCAs (4 volts or more) and my LOC could only supply 2 volts max. I purchased a Audiocontrol Four1 EQ/linedriver and completly solved my problem. The higher signal from the Audiocontrol was exactly what the Mtx wanted and the system sounded so much stronger and clearer. Never had a overheating issue from it again either.

A linedriver may solve your output issue, but that still leaves your noise problem. Im sure you have checked all you gains already, but what LOC from Stinger did you use? Not every LOC can be used with every car, some cars stock systems can conflict or even not work unless you have the correct one for that car. Whats all this installed in?

Thanks for the reply. I don't remember which particular LOC it was. I do know that it is for a FORD though. The install is for an 07' Ford Edge. I will talk to my friend later this week and see when she can go the linedriver route. I emailed ZED awhile ago and hoping to get a reply from Steve on this issue. I hope this fixes things.

Sure man, no problem. I hate it when its something small keeping ya enjoying your sounds. Hope you get it fix soon!

Steve agreed that this would be the solution. We will see soon.
