Hi Gang,

I am hoping that somebody here can help me out. I have been researching for weeks and am seriously confused.

I have a 2012 Lariat SCrew w/Sony and No Nav. I want to keep the stock head unit, upgrade door speakers and add an amp & sub.

My problem is that the factory HU (via the OEM Sony amp) rolls off at higher volumes to "protect" the *****ty speakers. I want a system that achieves balance at any volume (and doesn't cost a fortune).

I cannot figure out how to work around the OEM amp (without hacking, slashing and splicing) and, for simplicity, retain factory speaker wires. To make matters worse, I have stinking molex connections.

Can anyone tell me what the connections on the OEM amp (pictured) are?







Asking installers in my area has lead nowhere. They are willing to "do" it for me but refuse to give "free" advice.

HELP?

 

There maybe adapters for the problem. If there arent adapters then youll have to go with a new after market amp,, and basicly do that hack and slash thing. Its more a splice and cut.


try crutchfield for adapters.

 

Thanks a lot for the reply.

I have continued my research and may be finally catching on.

How does this look:

Factory HU ~~~ Aftermarket Harness ~~~ Factory Harness ~~~ Factory Amp ~~~ Audiocontrol LCQ-1 ~~~ Aftermarket Amp.

Factory Rears remain powered by factory amp.

Aftermarket fronts, tweeters and subwoofer powered by aftermarket amp.

I believe that this will bring the sound stage forward, provide a summed signal and off-set the roll-off.

Am I on the right track here?

Any suggestions on an appropriate aftermarket harness? I have been told that the PAC AOEM-FRD24 is not compatible with the Sony amplified systems.

 

You are on the right track and correct that PAC harness won't work. Since you have a DSP in the system, you need to tap into the wires between the DSP and speakers. Best place to grab the speaker wires are in the door sills or up by the kick panels.

Then attach those speaker level wires as input into a LOC w/ summing capabilities: Alpine LC6i, Maxxsonics MX-1 or a MTX Audio re-Q (REQ). You could step up to a real sound processor for time alignment, equalizer, and better cut-off adjustments. The LOC will then feed into your aftermarket amp which will drive your aftermarket speakers.
