Sure, a Cleansweep will work with a DSP behind it, just make sure you level match everything.

With a little more detail, you will probably get better advice however.

Which DSPs are you considering? What are your top three and why?

In most cases I would not recommend using a Cleansweep if the DSP can handle the OEM integration and summing you need. Why complicate the signal chain with another device?

 

Right now, The 3sixty.3 is on the top of my list. I was looking at the PPI/SS harmony but after some of the reviews I've read, it seems it's in my best interests to just pay the extra money on a reputable DSP.

I already have the cleansweep so I might as well use it.

 

If your alpine system is anything like my HK system in my 2013 Jeep SRT8 then it is going to be a pain in the nads. I am currently doing some work arounds to get good audio with my mosconi 6to8v8.

My problem is the stupid factory amp and signal processing. Might try the Pac audio interface. It allows tapping in before the factory amp.

Which particular PAC part are you referring to?


Hopefully more people will chime in here on this question. It seems like a reasonable expectation. I did email JL audio, maybe they will reply. I am working with an Infinity OEM system with 10 channels. An impulse purchase let me to owning an Audison Bit 10D which is a four channel in DSP.

 

I would look further into the wiring diagrams of your Uconnect systems. Wiring diagrams I have seen show a full analog signal output from the HU to the Amp. The amp used in the 2014 Ram for example shows amplified speaker outputs and additional outputs that are not used and "appear" to me to be pass-through.

Some have said to me that it can't be done and it would mess with the bus system but everyone who has said that to me has never actually tried it on these new units or on the same bus system. All wiring diagrams I see give me no reason to think that Uconnect HU that feeds the Amp should be able to be tapped, after-all, it is the same radio I am running without the Alpine system and I go directly from the back of my HU into my DSP and receive a full signal.

As for the cleansweep and a DSP, I would not recommend it. It would be an additional device you do not need and could cause issues with the DSP trying to shape the signal. These HU's are pretty clean and flat with a slight rise in the lower end, A DSP is all you need.

 

Yes, There is a full signal before the factory amp.....but.......you will need a DSP with a remote and volume control.

 

The clean sweep can't sum multi-channel OE systems back to a base "stereo" signal that DSPs require. Nothing out there can.

If for some reason you want to use the OE systems multichannel decoding, then you will need a proceesor that has at least 5 independently manually processed input channels (1 center, at least 2 for front left/right, 2 rears if applicable, and a sub). There can't be any summing of the center and rears to the fron left and right if you want to have a 'stereo' setup though. You can only sum the left and right channels (if need be). Then you can restore back to flat each channel and re EQ it to match the new speakers and/or any possible new mounting locations. Personally I don't like OE multichannel setups, or any OE setup for that matter. They compromise image and staging in order to have a better sounding louder system to multiple seats. They also work around the limits of smaller speakers with limited low end performance. It's just a big mess.

Your other option, if you can, is to turn off multichannel processing (ie logic7, PLII, "surround", etc) on the headunit and send out a simpler stereo signal of the needed channels to an OEM intergration processor. After that you can design whatever system you want like if you had a basic after market head unit to start with.

I would go with a JBL MS-8 if you want a multichannel setup like you have now.

 

If I'm understanding what you're saying, isn't that what JL's CL-SSI is for? The SSI uses your front, rear, and subs input signals and sums them to a full range 4 "channel" high level output that you then connect to the cleansweep that will then process the signal and fill in the frequency deficiencies and product a "flat" full range signal.

Ok, this is what I have planned for my 200. I have a set of Alpine Type R components I want to use for my front stage. I want to retain the center channel, mostly for imaging. I'm disconnecting the speakers in the rear doors and I have a set of Alpine Type R 6x9 co-ax's for the rear deck, and an 8" Alpine Type R sub (haven't completely decided where the sub will be located. The prevailing though is in the passenger side footwell tucked under the dash).

The factory Alpine amplifier, according to Directwire, is a true 10 channel amplifier. So, my speakers are crossed over actively. Hence my need for summing capabilities. After watching a rather informative video on RF 3sixty.3, it appears it will do the summing and frequency restoration the cleansweep and SSI will do. I like the 3sixty.3 because I can hook my laptop up to it for manual adjustments. The MS-8 is all done off a little screen and I don't like that.

I mean, it's a Chrysler 200. I'm not looking to throw thousands of dollars at it but I will make the investment on the right DSP because that is something I can take with me from vehicle to vehicle.

 

Snap some pics of the car and post! I haven't seen too many but they look great.

 

Was wondering what you wound up doing?
