Stereo Upgrade ??

Hello everyone, yesterday I started upgrading the factory stereo on my 2017 F250 Platinum but I have some questions. My goal is to do a full system upgrade minus the head unit. Yesterday i applied some Soundskins to all four doors and replaced the factory speakers with Focal components in the front, Focal K2 coax on rear doors. I plan to replace factory amp with Audio Control D6.1200 once is released so for now the factory Sony amps is powering the we speakers. So now to my questions :

1. Is it ok to use the factory speaker wiring even with aftermarket amps?

2. Anyone knows the factory Sony system frequency range for tweeters ?

Currently the Focal tweeters are not connected since I知 not sure if they値l get fried if I connect them to factory tweeter wires. I will not be using the Focal crossovers since I can set my own crossover points with the aftermarket amp. In the mean time I would like to power the Focal tweeters with the factory amp. Is this possible?

Thank you!

For frequency you may want to google search an audio forum... as for the wiring, most will argue its not the "best" but it will certainly work.

checkout crutchfield. They usually have everything you need from kits, wire harness adapters, and everything really lol. I upgraded my sound system on my 1999 and their speakers came with the wire harness adapters, din adapters, wire harness from my 19 year old ford to a nice kenwood system etc.

So I知 regards to the wiring, is this something that could make such a difference that can possibly affect the sound quality if deciding to use factory wires?

The factory tweeters are protected by an inline capacitor. You can't just ask what frequency the factory tweeters play at and expect the Focals to play at the same frequency as they most likely have a different impedance. I recommend you replace them with whatever Focal recommends for protecting those tweeters. This is good insurance on an active system.

Since you have the Sony system, you should consider bypassing it with the AmpPro AP4-FD21. Sony definitely cuts lower frequencies to protect their crappy speakers.

The factory wires will not affect sound quality, but may limit output a little. You are going to need to run new wires to the tweeters as the factory piggy backs them off the front doors (meaning you will have to reinstall the capacitors on the new wires or pre-plan and do it now with lots of extra wire under the dash).

Kreep, thanks for your response; yes my ultimate goal is to completely bypass the factory Sony amp as it is the amp what has the stupid crossover curves that tend to cut back on bass as you increase the volume on these Sony premium systems. But in my case Im upgrading not all at once and since I already installed the speakers I was hoping to get to listen to the new speakers powered by the factory system while I save for the rest of the components. Besides Im still awaiting for Audio Control to release their new D6.1200 amp. I called AD today and the projected release date is July 15th. I guess ill have to wait until i get the rest of the components before I can listen to these speakers they correct way.

That's a good plan. I suspect you would have to crank the volume with the Sony amp and run the risk of clipping. No sense damaging your new speakers. I do recommend you get some caps to protect the tweeters, its way to easy to accidently set the crossover too low and pop them...

Kreep, I was thinking of doing that but I知 not sure which caps to get that would do the trick. And yes if I set the volume past 20 I can tell there is a little distortion. So right now I知 not really cranking the volume too much in order to protect the new speaker sets.

Focal tech support can tell you. There are also online calculators.

Unfortunately my post count isn't high enough to embed links, so hopefully your Google-Fu is up to the task.
