This looks intriguing.

Pac-Audio.com Product Details | iPod Integration for your car and More by Pac-Audio - Connecting you to the future

PAC is coming out with a plug and play device that provides RCA and TOSLINK outputs without the use of a summing device and it seems to retain all controls from the factory. Of course something like this would come out after I just installed a JL Fix and had a splice-fest!

wow!! that's going to make upgrading a whole lot easier. I wonder what happens with the center channel and rear surrounds in the Alpine system?
I'd assume they are summed into their respective channels, front and rear rca outs?

If that's the case i will consider doing a full system upgrade (5 channel amp + stealth box) sooner, rather than later 👍

Not sure, I used a JL Fix-82 to upgrade my system a few weeks ago. I left the center channel and rear sails on the factory amp and I'm using the factory volume control instead of the volume knob on the fix. I have NAV and CELL coming through my Front speakers and the center speaker. Honestly, I dont think the center speaker is really getting in the way of the rest of the upgraded system. I have a noise floor issue I have to work out that seems to be coming from the FIX but its not really that bothersome.

All that being said, when this solution comes out, it will be MUCH better than having to sum and De-equalize the signal and I hope to switch to this instead.

I just called their tech support and confirmed what i initially thought.

The center channel will be summed into the "front channel" and the rear surround will be summed into the "rear channel" RCA outputs. This unit will be good for anyone looking to run a basic F/R/S setup.

No ETA on the release

Cool thanks for calling them, I emailed asking for a release ETA but hadn't heard back yet. At least your info tells us this is what alot of us are looking for! A basic F/R/S output with a flat response throughout the volume range will be awesome! The FIX is working well and doing what I need for now, but I'd much rather have this PAC device I think to feed to my JL TWK EQ because it will take the factory processing out of the mix.

Did they say whether or not this took the factory time alignment out? I'm assuming since this plugs into the HU side it does. I think all of that processing is done when the signal passes through the amp.

I'm also wondering if this has to be installed on the HU side, or if it can be installed just prior to the amp input. I'm hoping just prior to the amp input considering you have to go in there to splice into factory speaker wiring anyway. Doesnt seem to make sense to have you remove the HU just to pop this device in there.

yes, this will install right behind the factory head unit in order for it to process the full range fixed outputs and CAN signals the head unit sends to the Alpine or Harmon amp. I didn't ask about time alignment. I can only assume that could be adjusted using by adding a second DSP into the mix (Bit-One, JL Cleansweep, etc...).

Oh and BTW this will work for both the Alpine and Harmon premium systems (according to the tech i spoke to).

All you would have to do at the stock amp is disconnect only the speaker leads and extend them to your new amp.... Easy peasy.

One would think they'd make the harness tap in between the factory harness and the amp input then since you have to open up that panel anyway to tap the factory wires, but maybe I'm thinking too Grand Cherokee minded and not recognizing that factory amps may be in different locations.

Of course that would make it too easy for me to add on, now I'll have to run RCAs all the way to the back that I didnt have to run before lol

I will gladly run RCAs to the back if it means having a full range signal to feed my new amp.

Re: Pac ap4-ch41

Interesting. Accelerating my plan to add a StealthBox with a monoblock amp I already own. If I understand correctly, this would give me more options to upgrade additional speakers later?

yes, you would get true full range front, rear and non fading rca outputs. Perfect for adding a 4 channel + sub amp and or a 5 channel amp.
