Smile Adding a sub and amp in 06 Azera

Hello all, I have been doing some research and have an amp and sub that I have picked out. My want is to keep the stock HU but was doing some research and found that there are no RCA outputs on the back. Is there a part that I can get to add the RCA jacks or am I tatered and needing to bite the bullet and buy a new HU?

you have two options...buy an amp that accepts speaker level inputs..lots of them do. Or buy an amp that allows you to use the speaker level + wire to tap into the center pin of an RCA end. Rockford punch and power amps allow this.

Like wise you can buy a Line level converter like the Audio control LC2i or any LOC that allows speaker level inputs and proveds RCA level outputs.

To properly answer the question we need one question answered. Do you have the infinity or non-infinity system?
If you have a non-infinity system and want the system to function as the factory system would, you will need 4 channels (usually 2 units) of hi-lo adapters so that the balance and fade work properly. This does get a bit complicated and adds expense. You could get away with just using 2 channels (front or rear), but that does limit your ability to adjust the fade control.

If you have the infinity system then it gets REALLY easy. you use the two channels going to the DVC woofer (8") and feed those into your choice of systems (hi level amp input if it has it, hi-lo adapter, or LC2i).

To be honest, I've never found the passive Hi-lo adapters to be of any serious quality. What I fond works best is the Audio Control LC2i (if you have the infinity system otherwise you want the LC6i @149.99 or LC7i @189.99). It's not horribly cheap (I think i paid around $90 for mine), but it also allows you to adjust for the factory systems tendency to reduce bass output at higher volumes. It's what I used until I ended up replacing the head unit.
My headunit has some nice x-over systems integrated so I removing mine.

I hope that answer wasn't too long winded...
BTW all prices quoted are from Crutchfield, so you can almost certainly find them for less.

but aren't those signals already amplified? what about to tap to the rear speakers wires that are just before the factory amp?

You could do that. But then you have to work out the proper x-over frequency yourself. Also that means that once it's set up (set speaker fade first), you can never change the fade and have it sound correct.

The factory amp is a relatively good design (better than most aftermarket designs), just fairly week. Using the post amp signal won't cause you any problems at all.

All power amps that you will see in the market use multiple stages of amplification internally. What most (of the better) designs do is just inject the speaker level input after the first stage amplifier. So really this is one of those 6 one way half a dozen the other issues. The only thing to be concerned about is not over driving the first (factory) amp.

So if I do this do I tap the wire going to the factory sub, and also will it kill the factory sub. It is ok if this happens as I was going to tap that set of speaker wires if I could with the LOC so I wouldn't have to run the RCA, from the trunk to the the head unit. Also I had planned to unplug the factory sub anyway. Also I do have the Infinity system in there.
