I know this is an old thread, but I've been studying it for quite a while. I hope there's someone around who can still comment. I put an amp in for the sub in my son's car with a Wavtech Link2 line out converter. I used the wires at the factory sub to run to the LOC. I put an NVX 10" subwoofer in the factory enclosure. The subwoofer does sound better.

But now I want to put in an amp for the front speakers too, but I'm not sure how I want to go about that until I understand some things better. How are the tweeters and door speakers wired? Are they together, or are they separate? The OP says there are separate outputs for the tweeters and midbass from the amp. But I read someone else mention in the thread that they were together. Crutchfield has a write-up on their site for upgrading a Lancer and they mention the speakers being inline with each other.

Next question, are the line out wires identified by the OP actually low level line outputs? Someone else in the thread mentioned they didn't think they were actually a low level signal.

If the wires are actually low level signals, I can make them into RCA connections and then feed them into a crossover and then to a 4 channel amp. Then I can use the 4 channels to feed the tweeters and midbass (assuming they are 4 separate channels). Then I can feed the sub amp the same signal. I can have the entire fronts and sub running off low level inputs.

My other choice is to run the tweeter wires and midbass wires to a 4 channel LOC. Then run that to a 4 channel amp feeding the tweeters and midbass.

I really feel like I don't have any control of the system at the moment. I want more volume, but even though I increase it it doesn't do anything. I really want to bypass this stupid OEM amp for the fronts and sub. I don't care what it does for the rear; the rears don't concern me as long as something is coming out of them. I did some testing before adding the LOC and sub amp and I noticed that once the volume gets to 30 that's the max even though you can continue to 45. But once you hit 30 that's as loud as it's going to get.

Any help would be appreciated.

In my car, all the speakers had separate lines, it’s why I used a crossover for the tweeters and mids in the car.

The lineout from the deck is a low level output, I just converted it into an RCA jack and plugged it into the amp with no issues.

the stock amp has sound leveling control, so it won’t let you crank it up.

 

All this time I've thought I understood your setup but in your OP you said, ”The setup is running the front speakers on the front left channel threw a single crossover (for the tweeters, and mid range) and the rear spekers on the front right channel with the sub bridged on the rear amp." So you're using a passive crossover at the amp and feeding 2 channels into the Input of the crossover and then running the wires you cut for the tweeters and mids from the outputs of TWEETER and MID to the speakers? What passive crossover did you use?

 

I have another question. How can the factory amp have rear speaker outputs if it doesn't have an "IN" for the rear? If the rear outputs were on the head unit then the amp wouldn't have outputs for the rear. And if it has outputs on the amp then it's got to have an IN for the rears to be able to fade.

 

im currently trying to replace the oem RF amp but the pics of on the main thread for this arent showing up for can anyone help me out with the wiring

 

can you repost the pics or write the wiring i cant see anything on the og post
