JL audio cleansweep
May bee a noob question but mabey one one you guys can set me str8.
while i was buying the speakers for my new car the sale's guy talked me into buying the cleansweep. he told me that i needed this in order 2 hook up my amps 2 the stock GPS head unit in order to make it work.
but after talking to my trusted installer he told me (he never install 1 before and was not 100% shur)that the cleansweep was just a EQ and i dont need 1 two hook up my amps.
so do i need the cleansweep? my deck has a good EQ and my amp has 1 built in 2.
if i dont need it should i still use it in my set up?
or get rid of it?

I may be wrong here but I do believe that the cleansweep connects an aftermarket sound system to the factory deck. If this is the case and you have an aftermarket deck with a built in EQ and a sub out then you wouldn't really need this product.

Necessary? No.
Very helpful? Yes.
The clean sweep is not an EQ in the standard way of understanding an EQ (but yes it does equalize the audio signal.
Here is how the clean sweep works:
It connects to the speaker out-puts of factory deck.
You play the test CD that comes with it, and the test CD runs a series of frequencies through the CD-player and the clean sweep "listens" to the sound reproduction and alters the output to the most flat response it can.
This is helpful when adding aftermarket stuff because factory head units have a lot of non-adjustable EQ settings. Basically, the factory Unit compensates for the cheap factory speakers by causing spikes and dips where the speakers are too weak or too strong. These settings create a messy situation when you add amps and speakers that are more capable of flat response.
Really, the clean sweep allows the factory HU to give a flat frequency response like an aftermarket HU would.
If you like your current EQ controls - that's fine, keep using them - but be sure to set them at flat or 0 when you are setting up the clean sweep.
In the end, I believe you will be more satisfied with the sound through the Cleansweep than you would be with a basic line-output converter (this is the simple way to add amps to a factory system).
