Hey,
Im trying to add a aftermarket amp without changing the stock Head unit. But i was just wondeirng if there was a harness that was created or something. I know they have done it with the Scion TC a guy created a Add-N-Amp harness....

I'm just seeing if someone created one of these for the 2008 Lancer. Or if there is another way around to get the amp to run with the factory Head unit. but thanks guys.

 

You can wire a high-low converter in. You can even pick them up at Wal Mart. Run about $5-10. It just taps into the factory speaker wires and gives a set of RCA outs. You then run a remote turn-on wire to the fuse box, power to the battery, ground, and you are good.

If you can't find the converter let me know. I sell them for $3.50 + shipping.

 

ah, ok, i think i have a converter around here. But i dont have instructions on where they go. But ill just go to wal-mart and check it out to see if they have something. but thanks man. also where would the remote wire go in the fuse?.

 

put the remote turn on wire to something that will only run when the car is running or when you have the electrical on. possibly the headlights... keep swapping places until you find one where you get no power to the amp while the car is off--you'll drain your battery otherwise.

you may not even need to buy a converter if you don't want to. if you were about spending money you would have just bought a new head unit, right?

as long as your amp supports a bridged connection you should be all set. run wires from your speaker wires to their respective inputs on the amp (some amps even come with a high level input connector you can wire the car speakers directly into), from there simply run the sub off of a positive and a negative and you're done. one thing you will notice is that you do not have independent control over the sub and the bass will change depending on how loud you have the stereo (since you tapped into the speaker wires after all).

i own this amp: http://walmart.scosche-cars.com/prod...ductID=4694342 i use it for my speakers, but it will work fine for a sub. it has high level input via a connector so you can splice the wires from your speakers right into this connector and hook that up to the amp.

 

I would've added a aftermarket radio but i still wanna keep the factory one have the sun & sound package. Cant get rid of the 6-cd changer haha. Also i read on this forum that if u change to aftermarket that the stering wheel controls wouldn't work. But im jus thinking of jus running the converter so i can leave the rockford fosgate system alone and then jus hook the RCA's up through there from the aftermarket amp. But alright ill check which fuse will be the one for it.. But thanks guys if there are anyh other suggestions. Please tell.

 

there are modules so you can use the steering wheel controls--but i don't think there is one for such a new car yet.

i put a sub in the way i described in my friend's WRX since he also did not want to get rid of his 6 CD changer, hehe.

 

Please don't ever ever ever ever use the high level input on an amp. Ask any, and I mean any professional installer and they will tell you the same thing. Most decent professional shops don't do it either. They prefer running it to an aftermarket headunit, BUT if thats not the case, they 99.9999% of the time use high level to RCA converters.

You can tap the remote turn on wire to the "Audio" fuse in the fuse box.

On another note, why are you adding an amp if you have the Rockford system?
It already has the amplified sub and the stock speakers are fine with the power the headunit puts out.

 

o... But i just wanted to add my old system in it to get a little more boom boom. I have it sitting here collecting dust. But its a 2,200w(1200w RMS) audiobahn and just wanted to add it in. But im not planning on adding it just yet, I wanted to see what was out there to see if i could put it in without really changing anything with the factory unit. But Yea the fosgate system is good though. But i'm thinking i might just leave the fosgate in and probably sell the Other sub. But thanks for that tip.

 

oh, i didn't know you had a sub and amp... swap the amp in the car for your audiobahn one.

serious: what is so bad about using high level input? i haven't experienced any problems with it and neither has anyone i know who has done it. i'd like to know any issues for future installs.

 

yup, but idk yet, idk what issues the converters have. Never used one. But I might just hook up the converter to the left and right's and then jus leave the fact. amp and sub installed. and then jus install the aftermaret. one. Just one thing though idk the diagram of the wires. Dont know which one is Left(+/-) and right(+/-). If someone could tell me that would be great.

 

By all means, I didn't mean to sound rude or anything, so I hope you didn't take it that way.

With that being said, both ways will suffer in sound quality. But it has been proven in bench test that an amp receiving the signal from RCAs is cleaner. This is due to the converter box converting it BEFORE the amp. Otherwise the amp has to convert it to a usable signal and amplify it creating more work for the amp. If that makes since. I'm trying to keep it less technical for everyones sake.

Now, to an everyday listener you will probably never notice the difference in sq. Most can't and its even difficult for me without tools.

Ghost: There is no need to wire a set of the converter wires to the left and one to the right. Run both striped wires on the converter to the negative (-) of 1 speaker. Then run the solid color wires to the positive (+) of the same speaker. You then can adjust the level of the signal (left/right) on the box. Make sure they are both the same.

I have yet to remove my speakers to tell you which color os positive/negative. With it being Rockford Speakers in yours, the speakers themselves shold be labeled.

If you need anymore help, let me know.

 

simple enough, i didn't take any offense to it at all i was simply curious.

 

Ah... ok thank you for that clarification with the RCA'S n Converter. but alright ill give PM u if i need any help.

 

use something called an LOC(line output converter)
