Hello, I will be installing an approximately 500 watt amplifier to power two subwoofers in my friend’s 2003 Mustang GT, with the oem Mach 460 stereo. I have installed a few amplifiers in the past but never to an oem cd player. My question is what is the best way to get the rca wires to connect to the stock head unit. I have heard of it done with some type of adapter but am not sure of the name or where to find it. Any help would be appreciated, thanks.
ur probably thinking of an RCA adapter which i've seen doing decent jobs in a few of my friends' rides.
I think I found it, is a "Line-out converter" what I need? If so, is one company better than another or is one like in my link below fine?

Thanks for the reply, but those seem to be for wiring an aftermarket head unit. My friend wants to keep his oem 6-disk cd player so I am trying to find out if the line out converter is what I need to do this, and if so what brand or type is best. Thanks
Here is what I would do, get a good quality line out converter 2-Channel High Performance Line Output Converter - SoundGate.com this one is designed to handle alot of power, so tie it to the factory subwoofer wires. Might as well take advantage of the factory crossover and equalization.
Ok, so I started to install his setup and the amplifier is getting power and turning on but no sound is coming out of the subwoofers. I am assuming it is the line out converter since this is my first time working with one. Here is the one we are using: Scosche SLC4 Four-channel line output converter at Crutchfield.com Does anyone know if I need to splice into the speaker wires before or after the oem speaker amplifier? I have a feeling that might be our problem, or I messed up and spliced into the completely wrong wires. Anyone work with this part before have any info? Thanks guys.
So I called the Scoche tech support and I found out I need to tap into the speaker wires after the stock amplifier. I did this and got sound out of the subwoofers, but extremely little sound. A little while later the fuse for the stock cd player blew. I’m assuming the amplifier is not amplifying the signal, and the fuse blew because the cd player was trying to power the extra speakers? Could it be a bad spot for the amp’s ground? Does anyone have any ideas or suggestions? edit: this is the line out converter we are using: Scosche SLC4 Four-channel line output converter at Crutchfield.com
I began with the gain all the way down on both the amplifier and converter. I then increased both of them slowly to about half way and saw no result. I increased them both almost all the way up and still saw no improvement.
I am not a big fan of that LOC but it still should work, without blowing the radio's fuse. I need more info or I'll just be guessing Just Guessing First make sure we are hooked up to the speaker side (output side) of the amplifier. The best way to do this is to hook up to the speaker leads directly. Low sound output might be an indication that the inputs to the LOC are out of phase. I would pick up the audio for the LOC at the subwoofer. Blowing fuses (still just guessing) If the LOC is hooked up correctly it might mean that the Ford amp is seeing a load it don't like. I previously recommended a particular LOC for a reason. It works for high output applications.
wow I never updated this thread… We found out the problem and the LOC was fine, system works now and sounds great.
