? the jl cleansweep is essentially a loc on steroids, so i'm not sure why you say you want to avoid using a loc... it's supposed to be a nice unit, but pricey as heck. if youre satisfied with the head unit, use a loc, and spend the $$ it'd take for a loc on better amps or speakers...

What's an LOC?

I believe it's out mid July, thats what the guy at Tweeter told me anyway..
Whats a LOC?
I've been trying to figure out how to upgrade my stereo without loseing the RF head unit

LOC= Line Output Convertor, takes your high power (speaker) signal and converts it to a RCA line to your amps. The cleansweep has an internal LOC, as does the AudioControl LC6, and Alto Mobile UI-4.

There is room behind the oem HU. I have mine above the RF HU and my PIE amp below the HU, like I said, there is plenty of room.

thanks for the info . I will start to tear it apart this weekend and start plaining on upgrades

The CleanSweep is not an LOC. It has 4 channels of input and output with a 30 band EQ per channel driven by a very powerful DSP chip. It also adds an 8 volt line driver and Aux input.
The process is patent-pending and it's unlike the other units mentioned.
You can find information here.

Well actually it is a LOC, with the added benefits you mentioned.

Hey Sammy you know thats a jl rep there LOL

sounds like a LOC to me also, jsut using more complext calibration and algorithms. Not sure how much better it would be than a UI/4 because it UI/4 does not have calibration, However I think it is 4 times as expensive and exceeds the cost for a decent HU that would get around the problem in the first place!

I heard over $400 for the cleansweep...And for that much we could buy the new dash, and get a CD player with 8V pre-outs, Subwoofer Control and play MP3's also. All of which the cleansweep really cannot do. Unless you use the aux in and plan on using your ipod for MP3's but when you start with a crappy signal from the stock HU there is only so much you can do to improve it. I was planning to do this at first but after spending $500 on wires and Matt for the truck I jsut can't justify cheaping out on the HU.

A LOC typically use transformers to take a high level signal and step it down to low level signal. The CleanSweep can be installed before or after a factory amplifier.

I kind of figured that based on his posts. So maybe he can throw some products my way for unbiased real-world testing.

True, but my point is that it is performing the same function as a LOC, although it does it in a different manner, and has a line driver and eq built in. The LC6 can be installed after an oem amplifier as well. I can understand why you would want to disassociate the CleanSweep from "normal" LOCs, as it's hard to justify a $400 LOC to the average consumer.

I think this product definately has a market, I just couldn't see spending that much in order to retain the factory HU, especially when it lacks many of the features found on the most basic aftermarket HU. I bought my HU, PAC SWI-X and 12 disc for less than $400, giving me twice as many cd's to choose from, retaining steering wheel controls, MP3 playback, and I still have an auxillary input (without the poor volume level of the RF HU.) Not to mention I color matched my touch screen to the Titan's gauges, so it still has a somewhat factory look. I think the CleanSweep is better suited for vehicles with heavily integrated stereo systems, like the BMW iDrive.

"I just couldn't see spending that much in order to retain the factory HU".

Yeah, I don't see any sense in retaining the factory HU unless you already have alot of factory junk like NAV/DVD/XM.

Regarding cleansweep, it is described as follows:

"A particularly difficult challenge was dealing with the reality that a huge number of OEM head units now incorporate non-defeatable equalization curves aimed at correcting the response of factory speakers, as well as protecting relatively weak factory speaker systems from overload. Examples of these include bass roll-off at increasing volume settings, or severe midrange EQ to tame the response of OEM speakers. With previous integration solutions, even if an auto sound installer was able to find suitable analog audio coming out of the OEM head unit (or amplifier), the consumer could end up with severely compromised aftermarket audio due to OEM equalization (garbage in, garbage out)."

Per eakes' description of prior post, what is the point if the output of the factory HU is flat (no OEM equalization)?

Or what if any OEM equalization for the RF system was associated with the RF amp, downstream from the HU?
