    Hi SHO Forum!

    I am looking to do a full audio upgrade to my 2018 SHO. The “premium” Sony system just doesn’t do it for me. I had an aftermarket system in my previous car and took most of it out before selling it. Ideally I want to reuse as much as possible.

    My goals are:
    1. Replace the front door speakers and the front tweeters with a component speaker set. It doesn’t seem worth messing with the front 3” speaker so it will be disconnected.

    2. Replace the rear door speakers with a 2-way speaker system.

    3. Leave the rear deck untouched. I only have a 4 channel amp and I believe the doors would be the priority. The rear woofers and rear 3” will be disconnected

    4. Install a 12 subwoofer in the trunk.

    5. Keep the factory tuner as I’m happy with it but I want a flat signal that doesn’t change with volume.

    The biggest hurdle is going to be step 5. I have a Rockford Fosgate 3sixty.3 DSP from my last build. I could use its summing function to hook up to the high level from the factory Sony amp. That isn’t the best way though and I discovered the PAC AmpPRO AP4-FD21. It looks to be the best interface that can grab the signal before the Sony amp and then I could run a tos link to my RF DSP to tune.

    I was researching the AP4-FD21 and it doesn’t list Taurus years 2016+ as being compatible. Has anyone tried installing one anyway? Can’t imagine there would be that much difference. I took some pictures of the factory amp and it looks like it’s a different build than some of the other amp pictures I’ve seen online. Any thoughts are welcome.

    I have run high level to a DSP(better than stock but not impressed), then the RF DSR1(got it when first launched, was buggy and very noisy for me) which installs in place of the factory amp. The PAC installs imn the dash not by the factory amp and keeps the factory amp in place and working so my rear door speakers are still hooked up to it. Although I normally have it faded to the front so they are off unless there are passengers in the back that care. PAC also has an optical out you can buy if you 360.3 has optical input.
    I have a 2013 so I can say if it will work on a 2018 but my guess is it will. My amp does look different but as far as I know the ACM is compatible between 2013 and 2018 so it should plug in and work the same.

    Thanks for the reply, Lostneye. I would like to skip the rework and go straight to the PAC. I will try it out and get the optical adapter for hook up to the 360.3. If the FD21 doesn’t work then I will return it. Plan to order off crutchfield for easy return. The 360.3 is a little buggy to so it doesn’t surprise me that the DSR1 is buggy also.

    From your post it sounds like you swapped the rear deck speakers but left the rear door speakers stock. I guess I was thinking the opposite thing. Do you mind sharing why you chose the deck over door?

    The only stock speakers still in the car are the rear doors hooked up to the factory amp and as said they are typically faded off. The rest of the system is tweeters in custom sail pods, 6.5s in the factory front door location and 2 Image Dynamics IDQ 12s IB with a wall behind the back seats. No center or rear deck speakers. I was going for an SQ setup and after demoing a few really nice sounding cars most of which did not have rear speakers I decided to just leave the stock ones in. I have competed in MECA a little. The car won second place in class(street) at state finals last year and a couple 1st places with this setup.
    Like anything it depends on what your goal is. I have no plans on rear speakers and now with them on I find it more a distraction than it adding anything.
