Just wondering what everyone's opinion is on using this setup in the doors?
This is currently being installed in my 07Z and just wanted to get some feedback on pros / cons. Install also includes the following:
JL Stealthbox
JL 250/1 amp (for stealth box)
JL 300/4 amp (2 BA Pro 6.5" in front, Stock Rears only for fill. Or maybe remove the rears and send 150 to each BA Pro /shrug)
JL Cleansweep
VERY high end components for a very expensive car to short yourself on a simple aftermarket (Alpine/Eclipse) headunit that would complete the install....your stereo is only as good as its weakest link . Also up grade the rears while you're at it. Afterall we are only talking about a few hundred more dollars to do it right on an $80,000+ total expense!
The "JL Cleansweep" adaptor is only a rigged way of making a cheap HU have RCA outs. Any REAL high quality HU will already have these and your factory rears are most likely not 4 ohms either.
If we were teenagers on a limited budget for a used car in high-school I'd be more open minded to people cutting corners, but anybody that buys a new vette and ZO7 for that matter better not use "money" as a reason. You will be SOOOO much happier if its done right the first time.

I called JL audio and they said on the Bose C6 unit you did not need the the clean sweep especial if you are using the slash amps. Just tap in the Bose sytem before it goes to the Bose amp. You could take that money and apply it to speakers. Jl has a great Tec service department, I got it off of thier web site.
Nice set of stuff you have that. Like Cmooth72 said, a Clean sweep is not needed for a the Bose C6.
As for changing out the Bose headunit, I wouldn't do that. You'll ruin the factory look and invite people to break into your car. Beside, the headunit is not the weak link in the Bose system.

about the headunit. I decided not to change it because I couldn't find one that could adapt to the HUD on the C6 (you get radio/XM/NAV information in the HUD). To my knowledge there is no aftermarket adapter to replicate this function. So for the time being, stock HU stays in.
My installer is actually having a problem with using the cleansweep, maybe some of the pros or someone with experience configuring it can chime in ... basically he says there are 2 wires (signals) coming from the HU/factory amp to the doors. One provides the highs for the tweeter. The other is providing lows for the woofer (Door speaker looks like a 10" woofer/tweeter combo crap)... anyways, seems like if he uses either speaker to feed the cleansweep, it sounds like crap (speaker 1 give all crisp highs, no mids, speaker 2 gives only lows).
Also tried getting the signal before the factory amp, but said it didn't give him anything. I don't know how you are supposed to get the signal before for the factory amp, and not use the cleansweep at all. Maybe someone who went this route can chime in here...
Calling JL Tech support tomorrow morning to see what the recommended path is on this particular setup.
BTW I am using the cleansweep for the amps and the aux input for my ipod, since Nuecleus 2Xi isn't working perfectly yet. Setup sounds great through the Ipod --> cleansweep --> amps --> speakers.... but when I switch over to the HU it is plain crap.

"Money" is not the issue... just can't find a HU that can reproduce all the factory HU's bells and whistles. (i.e. output to the HUD). I do love the idea of an alphine W200 or similar, or even pioneer Z1 (I had a similar unit in my C5 corvette, and I miss the DVD playback and TV)... but I am waiting for a fully integrated solution.

What do you mean by "Slash amps" ... can you reference where you found any information on using the JL amps direct from the factory HU without the cleansweep or similar unit?

Nevermind... I did some research and found the solution myself. ECS cables direct from the HU (before the Factory amp) to the JL Slash series amps. Gonna give this a try tomorrow and hope for the best. Shouldn't need the cleansweep after this.
But going to need an alternative to connect my Ipod.
Will have pics tomorrow after the car is clean, and have sunlight for the pictures.
Only one more problem to iron out. Picking up some engine noise in the speakers. My installer believes that the factory HU voltage output is too weak and needs a line driver. We will be working on this problem over the weekend. Anyone have any experience with this problem?

You said you were running a Cleansweep. The Cleensweep already acts as a line driver by boosting the output voltage from the stock HU, which if I remember correctly puts out 2v? So if you are experiencing engine noise with the Cleensweep hooked up then it is not a voltage output problem.
Did the installer ground the aftermarket amps and all of the other components to one point at the battery? If not, that could be your problem. Professional installers sometimes have a bad habit of grounding to the seat bolt. Also make sure he didn't run the power wire near any speaker or RCA wires.

We pulled the cleansweep out. thanks to the recommendation of other forum members . (the cleansweep is not needed on the factory HU).
look at the end of my post, it details all the components in the final setup. But your info does point me in the same direction (2v off the factory HU is probably not enough, and most likely the source of the engine noise). Maybe my installer is on the right track. We'll see soon.
