Will I need LC2i and LC7i?

I'm changing all my factory speakers in my 08 crewmax limited including the dash speakers I'm am keeping the factory head unit I am putting component speakers in doors and will power with amp and taking crappie jbl factory sub out and adding jl subs my question is since I'm doing dash speakers also will I need the audiocontrol lc2i and the lc7i to make this happen

 

Contact Crutchfield or Car Toys to start. (or someone here who may have a similar setup.

 

thank you I'll contact him

 

Do you have the factory nav system?

 

yes I have the nav and jbl system

 

Our head units put out dirty signal.... So when I used my factory radio (the basic, not nav), amp and the lc7i, I had a low end white noise. To me after all the work I couldn't stand it, so I took the lc7i out and installed an aftermarket head unit. Problem solved.

As for my advice to you, if you want it, I would probably figure out a way to run an amp after your jbl amp. If you replace it and use a line converter you will probably get that white noise.

If you don't have a factory amp, which I think you do, I would buy basic line converters and run into the new amp. The lc7i will amplify the dirty signal and your amp still may do that... Anyway, if it was my truck I'd still try and see what it does.

If you get the white noise and can't tune it out... There really isn't anything you can do about it except un amp the speakers or replace with an aftermarket head unit.

As far as the lc2i and sub, you won't have any sound issues out of it. You shouldn't anyway. So that's a definite go.

There was another guy here that did what you are proposing and said he didn't have any noise issues, but a little bit later he reported that white noise.
