Okay, I've read dozens of threads on wiring in an amp, but I need some help. I have this connector. How do I know which wires go to the speakers (LR,RF, LR, RR) so I can wire those in from the amp? I tried to contact the person from whom I bought it but I have received no response. Thanks to anyone who can help! I have a 2011 XLT with standard HU and Sync.

 

I believe with that setup you just splice the wires together that match and with the rca out box you splice it into the matching colored wire. This is really not a "quality" setup and IMO splices are crap. I installed an amp and the pac harness is work every penny, it even give you a remote wire for the amp turn on. Just search PAC AOEM-FRD24 and try to find the lowest price somewhere. or go the route your already going down. just match the colors and splice them together.

 

Thanks, rymax. Regarding "splices are crap", don't you still have to splice into the speakers with the PAC AOEM? I don't see any other way to get the signal from the amp back to the speakers. With this setup that I bought, and the PAC, you are at least splicing in to the adapter, and not touching your factory wiring. The advantage I see from the PAC is getting two sets of RCA outs, but I can always get a Y adapter to send amp'ed signal to both seats of speakers. I hear great things about the PAC but is it really that much better than what I have? If it is, Im willing to switch.

 

The advantage of the pac is that it's not just the output of 2 speakers. The rcas are signals are from each speaker (left front, right front, lr rr) so if you wanted to add a 4 channel amp. And the splices are crap thing I mean I would solder the connections. But either way yea just match the colors and add the rca out to those splices that coordinate

 

"not just the output of 2 speakers, the RCAs are signals from each speaker"

I'm not sure what that means. Can you explain? I admit I don't know a lot about car audio. I greatly appreciate input from someone who knows more than me! I want to do this right.

 

The 4 rcas with the pac are one for each speaker signal. So one of them is front right the next is the front left and so on. This will help if you want the sub signal coming from the fronts or the rears

 

a little more info? what amp are you installing? does the amp have 4 rca inputs and 4 speaker outputs? are you using this for subs only?
pac question. don't you have to splice the pac wires too? Yes, but only if you are using the amp to amp the oem or aftermarket speakers in the door. but if you are only using the amp for subs then no splicing would be needed! also you are only splicing into the pac and for the wires going into the speakers from the amp so you are talking a tenth of the splices.

 

I am not looking to power a sub. Just a small amp like an Alpine PowerPack to help boost the stock HU to get clearer sound from Infinity Reference door speakers. Havent bought the amp yet but I believe it's as you describe. So I know I need two Y connectors for the RCAs (the harness I bought only has two outs) and I need to connect the remote power on. As for the speakers, I realized after looking more closely that the unit I purchased has the wires labeled so my original question is answers. I guess I just leave the speaker wires from the HU side of the harness unconnected? If there is a better idea for what I'm trying to do, I'd love to hear it.

 

Hey, so I need some help in this area as well!
I have a 2010 and still have the stock head unit. I replaced the speakers with some polks and have a clarion 300 w class D amp that I want to put in.
The neighborhood kid with car audio experience says since the head unit does not have RCA's it's going to be tough! The amp has to be set on high and it will run hot, etc. (I have no idea what he means)
Do these "PAC" things solve my problem"
Here is my amp

Thanks in advance

 

I believe this amp has a high/low level input selector. U should be fine. I don't know much about this amp but if you need rca input u need either a pac converter or do something like the op
