From my limited knowledge these are close to the same amps. Please help me decide which is best. (Quality and fulfillment of component needs)

I have f150 with factory nav

Precision Power PPI P600.2 Phantom 2-Channel Car Amplifier

This is a much better 2 channel amp if you want a lot of headroom on the power.

I'd recommend going with this amp though Precision Power PPI BK520.4 Black Ice 520W 4-Channel Amplifier

because I have that same set except its the 6x9 version. With these, they sound better going active where each mid and tweeter gets their own channel on the amp, using the amp's crossover features instead of using the passive crossovers that came with the set, which are kind of garbage in my opinion.

Ok this is new to me. I'm on board with using a 4 channel and active. How do I know how much power to mid or tweeter? and what to set the gains at? From what Ive read, going active these can handle much more power than 95 watts RMS.

Google up how to set gains with a digital multimeter. For 4 channel amps youll need a 1khz test tone
