Okay I am trying to add a aftermarket amp to my stock radio on my 05 rx330(non mark lev.) But does have nav and iPod hook up. I have a line out converter box (pac sn-35) for adding rca plug ins. Pretty much I need to know how to hook up just the LOC box if anyone knows. Only instructions I can find say hook the 2 gray(right+ right-) to the right speaker output on the car & vise versa for left. But my questions lie in the fact I have speaker wires for (R front-&+ R rear-&+ L front/rear-&+). So im confused what exactly I run the add on wires too. I feel like I am missing an additional 4 speaker wires possibly for the LOC. But truthfully I keep my radio on only the front speakers anyway.

Another question to add too this thread. First, realize I am on a college budget with few pennies to spare at the moment. I have a 2005 rx with broken key situation. Soooo picture this. I have the flat key for actually starting car, master key(key only, no fob,or anything else) as well as blank key with the whole set up buttons and all(I programmed buttons to lock and unlock doors). Finally my question. With extremely careful engineering what is the possibility to 1. Use new key set 2. Change uncut blade with original key(I no its a task in itself alone to interchange) and my main and really own concern 3. Remove chip inside of flat/wallet key and place inside of the new button casing? Someone just tell me it not only works in theory but as well might be possible lol. I need more than my own opinion before I embark on this shady situation.
