Ok guys well it looks like i'll be picking up two Alpine Type R's for my GS. Now my main question is something that I am sure is asked a lot. I have the stock '99 Navi in my car which I know has no RCA's coming out of it. This means that I will need an LOC correct? And that also means that I would want to connect the LOC to the existing Subwoofer wires correct? If not please tell me!

Thanks,
Elliott

 

Yes, connect the LOC to your sub speaker wires. You'll probably want to disconnect and remove your stock sub so it doesn't affect and cancel out your Alpines.

 

Yea i'll for sure be taking out the stock sub and using it as a port system.

 

thats the way. I have the same setup speakers in my car. What type of amp are you going to be using?
