JL Audio Cleansweep

[OldOneEye 10+ year member]

The Rockford 3Sixty.2 does it (as does the 3Sixty.1).

Main difference between the two is the equalization and xover. Both will take a decks volume dependant EQ and get flat it (so both use a 30 band EQ to unequalize the signal coming out of the factory deck (which uses equalization so they can protect speakers, use smaller speakers, etc.) Once they are unequalized and flat, the .2 has a 30 band EQ for all the outputs (the .1 has like 5 bands) as well as the ablity to do highpass, bandpass and low pass on the output channels. (the .1 has like a low pass I think for the sub output). So if you have amplifiers with built in Xovers and you want to use those, you can use those and can probably get away with a .1 instead of the .2.

The .2 is basically an Rockford EPX2 controlled by a Palm minus a few features. I am in the process of reviewing one right now for work and if you already have a Palm (or are considering the Palm or shortly something running the Windows handheld software), it is probably a bit more powerful than the cleansweep. It will also sum signals which the JL one requires outboard boxes.

If you are interested you can PM me and I can give you a price that is a little more aggressive than what is out there right now (I work for one of only 2 guys that are authorized to work online).

Is there anything out there that does what the cleansweep does and has the equalization feature?

What car is the install for? Does that car have volume dependent EQ built into the headunit?

If not, you can get an AudioControl LC8 or LC6 and save money. They do not do the signal flattening that the Cleansweep and Rockford unit do but they cost less. If you use them you also do not have to use a seperate volume control. You can use the one on your OEM headunit.

The LC8/LC6 are a little more than overglorified LOCs. They do signal summation, meaning if your OEM headunit (or amp in my case) sends out crossed over or bandpass signals.. it sums them back together into full range signals. They also boost line voltage to, I believe, 9.5 volts.

If you do not need signal summation or volume dependent EQ removal, I would recommend a high quality LOC like the NE-774V pr NE-7V found here. Cheapest of all.

I just had my system installed with a cheap LOC and it sounds pretty decent. I would however like to get an equalizer later on to clean up the sound a little more at higher volumes. My factory headunit i'm pretty sure doesn't have a built in EQ but I'm not positive. It's a 2006 Suzuki Grand Vitara luxury edition Maybe someone can find out if it does or not. As far as EQ's go, would any brand eq work the same as the next, and what type of eq do you guys think would work better? Also, would any of you still recommend getting something like the cleansweep over an eq? My system currently has focal components in front, focal coaxials in the rear, sub amp, 4 ch. amp, 2 12's in a sealed box. In about 2 weeks or so I'll be adding another 12.

wow all that sutuff and youre running a stock deck?

upgrade that bish

 

[Bolognablake 10+ year member]

Wow. That rockford unit is nice.

 

[Beerdrnkr 5,000+ posts]

I would upgrade the deck but it just looks so clean with the stock deck and it has a 6 disc changer and I have XM satellite for free for a year. I would also rather just get an eq to save some money.

I wasn't asking if you had an adjustable EQ built into your factory head unit. I was asking if they factory head unit applied varying Equalization to the signal depending on at what position the volume was. There are factory head units that do this to compensate for weaknesses.

I think you are confused if you are asking if you should get either an EQ or a cleansweep. Either you need the cleansweep and should get it or you don't and should just stick with a LOC (or one of the other solutions.) All of the possible solutions could benefit from adding an EQ in after the line converion, though.

Not all EQ's are the same. I am a fan of the ones offered by audiocontrol. But there are other great brands out there. Just if you get one make sure it is on par with the rest of your equipment.

I went through all of this a month or so ago. I feel your pain. I love the way my stock unit looks and integrates with the rest of the car... but I am considering upgrading to an aftermarket unit. My setup sounds great now with the LC8 but I am sure I can get better sound with an aftermarket piece. I am looking into the Pioneer AVIC z1 since my factory HU has NAV and is the same size.

Actually, for the most part the EQ is to protect itself (it turns the bass down at high volume, so at some volume it actually gives pretty good bass). It lets them put cheaper speakers on the thing and still be able to get good bass at lowl levels.

I'm glad I can use an aftermarket single or double din unit in my vehicle.

Yes, this is what I meant by weaknesses. Weaknesses in the system, usually not being able to produce bass at higher volume levels.

 

[OldOneEye 10+ year member]

OK, just wanted to point out that the automakers are cheap first, audiophiles 19th (or something like that). So they think "lets remove the bass at high level, and for every DB we pull out, we will probably save $100K in warranty repairs when the speakers blow". Sad, but true.

Ok, I see. My headunit doesn't turn the bass down at higher volumes from what I've heard so far and I listen to my music very loud. So I guess the best thing to do would be to just get an eq. What's the difference between a 5 band or 7 band etc. eq, is it just the more bands the finer you can tune your stereo? Would a simple 5 band eq work fine, as you can tell I don't have too much experience with eqs and tuning systems even though I had like 6 systems in my last car.

My old stock headunit used to change the signal... The higher up you turned the volume, the more it cut down on bass as some safety feature for the stock speakers.. it was a POS

the clean sweep works well. i just installed one in a G35 today and it went great. it uses the speaker signal cables from the headunit as an input and gives you front and rear RCA outputs, in addition to the aux input.

the clean sweep takes the signal from the OEM headunit (low/preamp or high) and adjusts the audio signal so that any equalization that the headunit was putting into the signal wold be corrected, sending a near flat audio signal to your amps.

if you wanted to tune the sound of your system you would add an EQ behind the cleansweep.

another option to the cleansweep is Rockford fosgate's 360 unit. i like it a little better because in addition to the front and rear outputs it gives you a sub output. its simplifies hooking put the RCAs.

if your stock deck has an aux input im sure it would work with the system. it would be just like you put a CD into the headunit.

before you go spending alot of money on either unit do some research and find out if your OEM deck actually equalizes the audio signal. if the OEM deck doesnt then you could just get a nice line out converter and save some money.

Why would you use a CS on a Nissan/Infiniti? Both of which with Blose have a flat unamplified signal to start. The CS actually is doing nothing to benefit the user. Just FYI for future..

Yes, the more bands the more control you have. Parametric EQ's allow you to choose the frequency (or frequencies) you cut or boost.
