Just as the title says. Any pros and cons for each. I have the base stereo

helix 82 dsp if you can swing it they need one more
person for the group buy. See 82dsp thread.
If not the cleansweep or a recode is the correct way to go.
Unless the other thing you mentioned can do frequency correction the
way a dsp can. (multiple bands)

I agree with PP82, but the GD one is for HiFi cars only.

If you upgrade the fronts on a base system don't you end
up in the same place as an upgraded hi fi with 82dsp.
Well pretty much especially if you ignore the back speakers.
Does using the 82 dsp use up very much range in straitening out
the eq on the base system or would you recommend a re code
to hi fi so it doesn't have to do as much de eq, just curious.

There is no amp in Base (stereo) defeating the purpose of the PnP GD. The point for the GD is to have clean, flat signal in, at the OE amplifier and then just replace the OE amplifier via PnP harness.

But you could get a Technic or other harness
I don't know if Helix has one. But what about the question
running speakers direct into the Helix as opposed to a Low
Level input have you done that experiment?

Yes, absolutely. We have done a ton that way. I wasn't implying that it wouldn't work and/or nothing was available, just that the GD doesn't apply.

I read once that once recoded to hifi you need to have the speaker outputs changed to Rca and until you install an amp you won't have sound. Is this right ?

[ctuna]

You can't do a recode without and amp
it changes the output of the head unit to 5
volts out . You can wire it up with any connector
but its a 5 volt pre amp signal after a recode to Hi Fi.
It won't drive speakers to any kind of satisfying level.
And that is true with the devices you asked about to.
LCI6 just shifts voltage levels no frequency flattening.
I think not to familiar with it.

Still didn't get an opinion on speaker outs versus re code levels.
I thought the general audio knowledge was that preamp levels
were always preferred to speaker outs. Just wondering what the
actual comparison was.

This question is better answered once you tell us more about what exactly you have in mind.

I currently have base stereo with morel ovation speakers and tweeters in door. No amp or anything else. That being said all I am looking to add is some new underseat woofers - most likely jehnert and an amp probably Jl xd600/6

OK, that makes sense. Best thing to do would be a recode to HiFi. Then you have two options:

1. Add the JL amp like you are planning to

or

2. Add a processor/amp combo.

The addition of the JL amp in combination with the HiFi signal will give you a flat/clean input for them amp. It will make everything sound cleaner/crisper/louder. However, it will not give you a better soundstage and imaging, and the final frequency response will not be ideal. That you can only achieve with a DSP.

Having a good soundstage and accurate imaging are critical components to having a good sounding system.
