has anyone done this.. i mean wouldnt this do the same thing as getting an aftermarket deck as far as quality goes? im thinking just throw in a aftermarket equalizer and switch out all the audio components except the stock deck and a 10" sub and amp.. im no audio expert but i would assume this would improve the sound quality just like an aftermarket deck would..

 

that's my plan, too. I picked up an audiocontrol lc6 and eqs a few weeks ago.. but I'm going to do the front speakers first w/an amp and components. stage 2 will be 2 12"s and another amp.

there were a few people mentioning that they used aftermarket eqs to flatten out the frequency response of the stock headunit.

 

That would be nice, but the sound quality still sucks. I first tried the Stock HU to LC6 to the DQS to after market equipment. After several months of disappointment, I got the dash conversion and an after market deck. I couldn't be happier.

 

The EQ won't be sufficient to compensate for all of the internal processing that the BOSE HU uses.

The JL cleansweep appears to be a better way to do this. However, I am still highly skeptical as to whether or not it can really remove all of the processing that the stock hu uses. I would think that given JL's reputation, as well as their financial ability to research and develop products, that the product might actually work well. For now, i'll go out on a limb and say it is a better alternative to an EQ. Especially in our cars where there is a lot of processing involved with the Bose HU.

Will an EQ help you? Yes. Absolutely it will. However, it is in no way comparable to a quality aftermarket hu. It all comes down to how much of an improvement you are trying to achieve, as well as what your budget will allow.

 

Does the HU "processing" depend on what the source is? That is, does it treat all of the inputs AM/FM/CD/SAT the same? I have the PAC AAI-NIS Aux INPUTS to the HU and that input seems to sound really good after replacing the front speakers with a Kenwood component setup. There is still some muddiness in the low end (but plenty of punch) with the remaining rear Bose speakers (I dialed those down a bit so as not to overwhelm the clearer sound from the front speakers).

 

check for my post on adding an alpine sound processor. It more than makes up for the bose shortcommings. Its a substatial sound improvement.

 

You can keep your stock head unit and still get quality sound, try looking at the JL audio Clean Sweep

 

clean sweep looks nice! wheres a good place to get one? and a LOC thanks guys

 

any idea on the exact release date of the jl audio clean sweep, I called them today and they thought JUne, anybody else have some info?

 

The only people that know when the cleansweep will be out is JL Audio. I'm not even sure if they know themselves. They have a history of delaying products, so don't hold your breath.
