Now tuning a DSP can be a different story, you can spend a lot of time on tuning if you are into it. The speaker output wires from the factory head unit are connected to the DSP and then you can connect low level rca connections from there to the amplifier. Installing them is not really any more difficult than installing a high level line converter. That said, There is a significant improvement in sound quality with a good DSP. You can use simple high level speaker converters to get the low level signal for your amplifier, and some amplifiers are actually made to take high level input from the head unit speaker outputs directly.
