PAC OEM-1 vs JL Clean Sweep

I went to my local stereo shop today, and I talked to the guy I always deal with, and he knows his stuff. He told me that the PAC OEM-1 is going to be a waste of money. He told me that the reason why is because the factory head unit is not sending out the low frequencies thats required for the subwoofers. In my previous truck, I had an aftermarket head unit and 2 12" subs, and I'm used to the crystal clear base i was getting.

 

He showed me the JL Clean Sweep, and it does a lot of things I'd like to do, but the downside is the price tag. Over 500 bucks Canadian!

 

Is it going to be worth it? Or should I just grab a PAC OEM-1?

I'll give this a bump, because I want to know the same thing.

 

I have a PAC OEM-24 for mine, but I have yet to install it until I find out more about the Clean Sweep. Every stereo shop says that the JL is the way to go, but they stand to sell it for $350, vice selling me nothing (I already have the PAC).

 

I'll be replacing everything but the head unit.

If you have to choose between the Pac piece or the JL audio Clean Sweep you should definetly use the Pac piece. The JL clean sweep is a good converter for cars (i.e. Benz, BMW, etc) that don't have direct connect adapters like the Pac adapter for the GM's. Just make sure you have the correct one.

 

Its a no-brainer. Less money and works better.

 

If your going to spend the money on the clean sweep, you should just buy a new headunit.

I think I'm going to try the PAC OEM-1 first just to see how it works out. If i'm not satisfied I'm going to grab the clean sweep. I don't want to get a new head unit because im getting a factory navigation system so it works with the steering wheel controls. I'll let everyone know how it turns out.

 

The only problem is I can not find ANYONE in the local area that stocks the PAC OEM-1. The reason my stereo shop says they dont stock them is because they don't do a great job of it. They had the rep come to their store, and they tried them in a few customer vehicles but after they were all returned they decided not to carry them. I am hesitant to buy one off the internet because of shipping and the difficulty of returning it if it sucks.

I'll be keeping my stock head unit for the same reasons...Factory Nav, touchscreen, steering wheel controls, easy interface with the rest of the truck...I don't want to toss it.

 

I bought my adapter from JPCustoms.com, not a problem there. They're well know around here as a stand-up place to do business.

Exactly what I was going to say.

 

JL's just taking a bad idea and making a lot of hoopla about it. Every output stage adds distortion, and with clean sweep, you have the radio output stage, and then the clean sweep, and all its bells and then the final amp's output stage. It can't possibly be as good as a radio with preamp outputs feeding an external amp, ergo a single output stage, and half the distortion that a JL user would be stuck with.

I don't have the touchscreen, but Pioneer makes an interface for using your steering wheel controls, I am currently using it. Initially I was using the PAC interface to add a two amps for different front speakers and a sub. It worked fine until one day I took my MP3 player out and plugged it directly into the amp and played the same song that was on the stock cd player. The difference was amazing. So much more bass. That started my search for a new head unit.

You're lucky you had a way to hear what you were missing with the inferior GM unit.

He told me that the reason why is because the factory head unit is not sending out the low frequencies thats required for the subwoofers.

 

 

 

 

not quite...

 

The 2003+ Bose factory head units output a full range 20hz-20khz audio signal. Contrary to popular beleif, the audio signals coming out of the factory head units are not "bose equalized" or "messed around with" or "crossed over"...the low level audio coming out of a 2003+ factory radio/head unit is perfectly good. They are straight and pure, identical to any variable low-level RCA signal you'd get out of any aftermarket head unit. All the Bose stuff happends downstream in the amp itself.

 

If you want to hook subs up to a 2003+ factory head unit, use a PAC AOEM-GM24 module and it will sound perfect :driving:

This is exactly what I did initially because I wanted to retain the factory head unit for anti-theft purposes. I have the same system listed in my sig with the factory (non-bose) unit. It sounded pretty good at lower volumes, but I never could get the bass adjusted for higher volumes. Then one day when I had some time I burned a CD and also transferred the same songs to my mp3 player. I could not believe the difference. It was night and day. I went back inside and started my quest for a new head unit then and there. I only know what I heard and the stock unit clearly pulled out the low frequency as the volume went up. And if you still want the PAC unit, let me know. It is sitting in a box in my garage.

you didnt read what I said. :driving:

 

The 2003+ factory BOSE head units output a clean unfiltered full range (20hz-20khz) audio signal. The non-Bose head units output a filtered AMPLIFIED signal designed for the factory junk Delco speakers...theres no sub, or external amp so naturally the built in EQ of a non-Bose head unit is going to be tuned for no sub, with low freq's being rolled off as volume goes up.

 

2003+ non-Bose head units have an internal amplifier (well all the head units do, individual programming dictates whether the internal amp is used, or low level signals are passed thru, but thats besides the poitn) that sends speaker level signals out the back of the head unit. When you plug in a PAC AOEM-GM24 to a non-Bose head unit it takes these signals and loweres them to a line/low level signal...its literally just being a junk LOC. And with LOC's, garbage in/garbage out.

 

with Bose head units its completely different. The PAC extracts the pure untouched full range audio signal, and it sounds good...

I have a 2007 Tahoe LT (3), and at first I installed a DVD system and 2 Alpine amps and cleansweep to work with my stock stereo. No Nav. It totally sucked because I had an external master volume and I had to play with my stock stereo and master volume knob to get a good beat. The worst was that my chimes and turning signals were also amplified and it was freaking anoying. The people accross the street can hear it and it was embarrasing.

 

So I took it back and they suggested to replace the stereo. So I did and got the Eclipse 6600 Head Unit and it's awesome but now I don't have Onstar, chimes, and parking assist. They said they haven't got those modules/interfaces in yet and that supposeably they are still working on one that will work with my 07 Tahoe. Got to work the steering wheel controlers and Ipod for an extra doe, but worth it. They took back the cleansweep and credited me toward the new install.

 

I still kept the dvd system and now I can watch what the rear passengers are watching in the eclipse unit, and vise versa and watch a different movies/videos seperately.

 

If you guys know of where I can find the Onstar, chimes, parking assist interfaces for my tahoe/eclipse unit I would greatly appreciate it.

Oh and it has/was a bose system.  :happysad:

 

 

 

 

noboby makes anything for the -900's yet. It will probably be a while because they (PAC and other adapter companies) have to figure out the new GMLAN data bus.........

 

 

 

 

 

Hey thanks duramaxHD, so I guess I have to keep on checking back. I hope it's soon.

      Missing thrust bearing? And oil selection

      By Chuck FB · Posted

      Yes I agree, its what amounts to free advertising to let people know about his UOA testing company, and not that there is anything wrong with that but certainly that is a motivator for putting out videos about the science of oil as well as other topics such as oil and air filtration etc. The interesting part I found with his last video is not only the physics behind the reason for the varying wear due to a diesels working torque range causing more bearing load and that higher viscosity oil is of benefit, it was also that the chemistry behind the GM Dexos 0W-20 and the Mobil Dexos licensed 0W-20 are far enough apart that its showing up with a difference in wear even though the two oils are matched in viscosity and in that comparison viscosity was not having the finger pointed at it.    There are a few youtubers out there or one anyway that I have watched a bit of who has gone through the pains of accessing various countries manuals for a certain engine platform and while in the US/Canada it may say use 0W-20 or what have you for some Toyota product, in some other countries it sings a very different tune for the very same engine with the typical traditional oil viscosity/ambient temperature charts to help choose which oil viscosity is correct for the conditions the vehicle will be used in and in some cases its taken an engine in a US manual that states only use 0W-20 as per warranty coverage and yet that same engine in certain other countries may have up to a 15W-40 etc oil option that meets the spec. Another words the guy who is driving through Death Valley or Phoenix and south weather at 120f is often being fed a line of bs by the US system that has forced vehicle companies to restrict the warranty to a specific low viscosity oil for anterior reasons as well as the long drain interval suggestions.    Thankfully youtube is free ( yet anyway ) for viewers to sift through information and of course comes with the good and the bad ( truth and lies ) and we can choose to turn off/not watch what a person finds is bs or just not interested in the topic.

      No doubt... But, as someone who doesn't pay for his services, but who has provided a few views/clicks on his Youtube platform, the data around the Mobil oil testing I think does have some value including to "freeloaders" like me.   A lot of what he's doing is likely showing the OE's work in their oil selection, something that many of us had kind of assumed was true all along, a good balance of both excellent protection and efficiency.

      Lake Speed is drumming up business for his company just by being in the spot-light so he has a vested interest in stoking the 0W-20 fire.  IMO

      I knew when I bought my truck that it had off road hill decent or craw control or whatever they call it and rolled my eyes at that but it gets throw on with other options my truck has, I just never had a heads up if the highway speed regular cruise setting had anything to do with the brakes and that took me by surprise. If you've ever been to the top of Pikes Peak and watched those ahead of you on the way down with their brake lights on constantly, one can guess they are probably not gearing down or not enough anyway if their vehicle will allow and a good reason their is a brake check spot part way down where they use an infra red heat gun to check how hot ones brakes are front and rear.    Your right that once one gets out of the front range by Denver and I've not been on that stretch of 285 between Denver and Fairplay myself but I know its high and Fairplay at 10000 feet, Buena Vista at 8000, it drops a bit from there but then your going back up and over the 11000 pass and Durango is at 6500 . So yes your definitely right that 6500 and a lot higher is the theme of going anywhere out in that direction from Denver but hey, the down hill sections give fantastic fuel mileage !.    I don't even look at the fuel pumps for what premium costs here, since I live on a farm and up to this point get fuel delivered I am rarely in front of a fuel pump and when I am, I am often using card lock bulk fuel stations so it tells me what the price is AFTER I buy the fuel. Looking up on gas buddy and converting to US gallons but in Canadian dollars, regular on average of the prices listed was around 5.95 and premium is around 7.00 . That was one reason I did not go for the 6.2 half ton aside from its lack of carrying/towing if one was going by the rule of using premium fuel and until recently one could only buy regular farm gas if playing the few cents off game for farm dyed fuel for a "farm licensed pickup". But yes I hear you on the fuel price difference and like the diesel theme with it often being more expensive then gas it doesn't have quite the charm to it either as it once did although right now here for some reason the price of diesel has come down more so its now inline with the price of regular gas.

      I agree with this assessment. As you know I’m testing longevity with vehicles for the first time. I have a few vehicles I passed to kids and grandkids. We’re all past 100K miles some approaching 170K. I’m the only one doing 5k oil changes. The rest whatever the minder says. I’m the only one doing frequent transmission service. My odyssey the trip vehicle at 200K will be finished as a trip vehicle. I recently changed to high mileage oil, Valvoline. I can’t get past the fact that all manufacturers want to claim long service life. I just don’t make sense that they would go with low weight oil for mileage. While sacrificing longevity.
