WK2 Audio upgrade question: LC6i or Cleansweep?

I have read countless audio upgrade threads for the WK2 with the factory Alpine system. A lot of people are using the LC6i in between the factory Alpine amp and the aftermarket amp. Running components up front. The question I want to know is, what do people think about the JL Audio Cleansweep? I have thought about going this route instead of the LC6i.
As seen here.....

JL Audio CL441dsp CleanSweep® Sound processor for use when adding amps and speakers to a factory system at Crutchfield.com

The question I have is does the factory Alpine amp send to the front speakers a full range signal, or will I also need to use the Signal Summoning Unit as well? This unit is added when the factory amp system doesn't send full range signals? I.E. are the factory fronts crossed over or no? This is the addition?

Re: WK2 Audio upgrade question: LC6i or Cleansweep?

Greetings,

From reading your posts, I sounds to me you keeping the factory radio.

The Alpine Premium factory amp includes the Alpine's preset version of Euphony 7.1 surround sound DSP, along with predetermined time delay's and crossover points for each speaker. I have yet to find out the crossover points for the speakers. Remember, the Euphony is steering signals to each speaker, just like a home theater setup. Therefore, to get the best full range signal is to take the front speakers (midbass and the tweeter) and the subwoofer channels and sum those signals together to get a true full range signal restored. The other option you have if want to keep that Alpine DSP functions and add aftermarket amps and speakers is to go with a hi level converter into the aftermarket amp input. If the aftermarket amp does not hi level inputs, then you need a converter which is easy to get.

Experience Alpine - Jeep Grand Cherokee

To answer your questions about products:

The new LC7i is the way to go over the old LC6 for OEM integration.

With regards, to the JL Audio Cleansweep, this is a basic 4 channel dsp that give you no provisions to tailor the sound with an eq, etc. IMO, you are better off in looking at the Audison Bit Ten units which are 5 Channels. SoundMan Car Audio out of CA. speaks highly of the Audison Products (they sell it also and ABT.com) and the start around the same price as the JL Audio. Check out their forums, lot of great information on the website.

Audison bit - bit Ten
SoundMan

Best for now.

Thank you for the response.I was.leaning towards to LC7i between the factory Alpine amp and new amp. The new amp is going to be Alpine PDX V9 to power Focal IS 165 components up front, Alpine 10tw tweeters above the liftgate, and a JL audio Stealthbox. So, if you have advice, Get the front signals to one channel each, rear signal to channel.each, and subto channel? for a total of 6.channels?

Yes, I am keeping tje factory 430 headunit, and keeping the stock Alpine amp to power to rear doors and in dash speaker.

Greetings,

You got a nice game plane.

I am not sure, but the Alpine tweeters might be to harsh and bright. I would check out a midrange speaker that has frequency range from 100 -18,000 hz.
Look at partsexpress.com and madisonsound.com.

Use this as a reference (it is expensive):
Pioneer Stage 4 TS-S062PRS 2-5/8" component midrange speakers at Crutchfield.com


With the LC7i after you sum the channels, you will have a 7.0 setup. This is also common when you keep the bass together with front speakers.

Best for now, have to run.

Greetings:

If you are getting this done by installer, this is what they would mostly likely do for your setup.

For the LC7i, look at the bottom diagram on page 11 of the manual for summing.

http://rs.audiocontrol.com/company_38//OM_LC7i.pdf

For the Alpine pdx-v9, study the manual a little:

http://a248.e.akamai.net/pix.crutchf...00PDXV9_DL.PDF

The sub out of output # 3 of LC7i gets hooked up into the Alpine PDX sub input with the switch set to SW, you did the correct summing with LC7i and Alpine can not do the correct summing.

Output # 1 out of LC7i get hooked up into the Alpine PDX channel 1/2 with HP setting to x1. We are using the Focal passive crossover.

For the liftgate speaker, IMO, I would take that signal directly from the factory amp, convert it with a high low adapter to preserve the surround sound steering. The rca cable will then go into channel 3/4 of the Alpine PDX input switch set to 3/4 and the crossover filter to off, this way you are using the predetermined settings from the factory amp. If you do not like the sound of the rear, you can always change it.

Let the speakers break in according to the manufactures recommendations, and then come back to adjust the accubass settings in the LC7i and the Alpine PDX crossover points.

Best for now.

I compared and their seems to be not much difference other than the RMS. Is there a difference between mounting a seperate crossover as in the Alpine above, or a built in crossover like the Focals?

Re: WK2 Audio upgrade question: LC6i or Cleansweep?

Also, with the PDX v9 being a 5 channel amp, one channel is the left front, one channel is the right front, one channel is left rear, one channel is right rear, and final channel subwoofer?

Greetings,

For the Alpine PDX v9, you are correct with the connections.

The advantage with the Alpine SPR-60C speakers, the crossover gives you the ability to bi-amp them resulting in even a better sound quality. To do this using PDX v9, channels 1-4 are dedicated to the front and the last channel is for the sub. The factory amp works in the same principle were one channel is for each speaker. When I upgrade my self in the future, the fronts will be bi-amped.

You should try to find a place near you and demo the speakers and see how they sound.

Best for now.
