5 Channel Amp/High Level Input
 
Hi Guys,

I was hoping someone that knows more than I do can give me some clarification installing an upgraded sound system into a 2010 SCREW with the basic SYNC radio. I'm going to leave the factory HU and add a 5 channel amp to power 4 upgraded 5x7 in the doors and a single 12" under the rear seat. My first question is if the amp has high level inputs built into it is it necessary to use a device like the PAC AOEM-FRD24? Does it provide anything i'll need other than Low Level/RCA output? In other words, will using high level inputs maintain all of my factory HU's functionality? Second question is do I need to run new speaker wire from the amp outputs to all the door speakers? Does the PAC make this unnecessary?

I read lots of other threads but was not able to find these answers directly stated. Thanks in advance

If your amp has high level inputs, I would use the Metra Bluetooth harness. I forget the model number right now, but this will give you speaker level outputs without having to cut any of the factory wires. Most amps that have speaker level inputs do not need a remote turn on wire because they sense a signal from the speaker wires to turn on. Using the less expensive Metra harness will make the PAC unit unnecessary. I always use all new speaker wire in my stereo installations, but if I understand how the Metra harness works you might be able to get away with just running speaker wire back to the Metra harness. That would at least save you from having to run speaker wire through the molex into the doors.

The pac harness is nice cause it coverts your wires to rca for the input side of the amp and gives you a remote signal wire. And it's makes wiring so darn easy. But you are going to have to modify the harness cause it is built for ouput and to retain stock signal to speakers. I just cut the wires going back to the wiring harness to the truck and thats where I solder on my output wires from the amp.

You guys are lucky. For those of us with the screen in the dash we have no options

There are options. I picked up an audison bit ten that installs after the factory sony amp. This is a more complex system that has to be set up on a laptop but if you love sound quality, it's the way to go. This leaves your stock sony nav head unit and you don't need to even go behind the dash.

I guess I should have been more clear. We don't have any options that don't require breaking factory wiring. I would love to have a plug-and-play option for my truck (13 xlt without sony)

King Nothing-

What wires would I need to cut that the Metra kit would would avoid? If it is just tapping into the back speaker for the high level inputs I was not to worried about that. I'll also cut the wires at the speaker terminals if I'm going to run new speaker wire from the amp. Is an adapter or kit necessary to retain all of my radio/SYNC functions including Bluetooth?

You would either need to cut or tap the factory speaker wires. If you want to retain your front/rear fader control you would have to tap all 4 speakers. If you aren't concerned about cutting speaker wires you could cut them, run speaker wire back to your amp input, then run speaker wire back to where you made the cut and hook it up to the other side that you cut. Note that this is exactly what the metra harness does, only you cut the metra instead of factory wires. I dont think tapping just the rear speakers will allow you to keep sync. I think you would have to tap the fronts for that

Interesting. I'm looking for the Metra kit. Do you have a model # or link by chance?

I liked the FRD24 myself. the only wires you cut are within the FRD24 and not one oem wire needs cut. it gives you RCA outs, you run them to the amp,,, then you run wires from the amp speakers out into the FDR24 which then feed all the speakers in the truck. I did my in my house and all I had to do is hook up the amp, unplug the Head Unit connectors and plug in the FRD24 and I was up and running... sync, steering wheel controls and everything works just like it did from factory!
