Re: Line out converter install pre/post amp
If you have the Alpine system, and install LOC before the factory amp, you lose control of your signal (which my not be a huge impact if installing sub only). The processing (bass/treble/mid EQ) is done at the OE amp. I'd also recommend an AudioControl LOC before the PAC unit. If you ever want to start replacing your speakers, you'll need an AudioControl LC6i at minimum. If you only plan to use an aftermarket sub, and leave everything else alone, and LC2i works great.
