Vehicle: '13 f150 supercrew non-sony
Setup: two sundown e8v2's off an alpine mrp-m500

Everything is ran through the stock unit via LOC's. it sounds like the subs arent playing to their full potential. Gain is set correctly and lp filter at 75hz on the amp. Is it possible the LOC supplying the amp is a high pass signal thus not recieving the lower frequencies, or does this not make a difference? Bass EQ is set to +3db on the amp. Am i right in thinking raising the bassEQ is a bad idea? Possible solutions?

I'd check the setting on your amp. I was in the same situation with mine but I do have the Sony nav. I had wired my subs to the old sub wires that were under the old seat but my amp has the ability to send the signal shared from the front/rear speakers or use the dedicated input from the sub line. I accidentally had mine set to the front/rear at first and since the signal was already crossed over at the amp, the subs got very little signal. When I pushed the button on my amp to change the way it handled inputs, it worked great. So try there and make sure the amp isn't pulling inputs from just one set of speakers vs two vs thinking it should have a dedicated signal and see if it helps at all.

Else - you should only need 1 LOC. A 4-channel LOC will take the signal from the front plus the rear and combine them for you. Then, if you're wanting to retain your Sync stuff (so the voice comes from the front only) you'll still retain that if you're amping the signal and sending it back to the front and back. ...although if you bought 2, 2-channel LOCs then you should be fine too.

They had it faded to the front. Adjusted back to the middle and all is well. I believe they used 2 2ch LOC's.
Beings im using the stock headunit i dont have the adjustability to just control the doors and just the subs, correct?

If I understand what you're asking... not really. You could buy a PEQ for your sub and run it to the front somewhere. That's a little **** that controls the gain for your amp. Then you can control it separate of your front speakers and it'll give you the control you're looking for (just the opposite way). A PEQ usually is about $20-25.

i did have a bass **** installed if thats what you're referring too.
What im saying is, when i fade it to the front (components up front) i would want the subs to remain at the same output wise. When i do fade it to the front now the subs getting quieter bc of it.

Not ideal. In that case they should run the sub amp off the front outputs.
