How to install a line output converter?

Question

i am hooking up a sound system to my 2005 vw golf. i am keeping the stock head unit and wanted to know how i would install the LOC and which wires to connect. i was told i could wire it to my stock amp in the hatch. also, which LOC would your recommend, the Metra or Scosche?

Thanks

Answer 1

You can connect the LOC by the amp in the hatch.  A few things to remember, be sure you tap the line outs from the amp.  If you accidentally tap the line ins, the signal will be so low that you'll barely get anything from the speakers (i know this because I've done it).  

Secondly, you'll also need to either tap the stock head unit power wire or the amp's power wire in order to power the LOC.  You might as well tap the amp's since it's right there already.

Make sure you find a wiring diagram for the amp, so that you're tapping the proper wires.  For the signal, you'll need to tap the R & L speaker outputs from the amp, and obviously power for the other.  Be advised though, I don't know how the 2005 VW amp is set up.  If you're adding the LOC to be able to add a sub, you should find out first if there is any built in crossover or filtering going on in the amp.  If there is, it might be filtering out the subbass frequencies to protect the stock speakers.  This would make you're LOC useless for adding a sub.  You might want to check out vwvortex.com for more info about that.  Im sure someone over there knows.

As for Metra vs Scoche...it really doesn't matter.  They're likely to be very similar in quality.
