Does anyone know if the factory wiring of the dash and doors is done in series or parallel? Also will a Rockford Fosgate 30 watt rms (45 max) amp make the sound clearer and louder rather than a headunit (JVC I think 20watt) and / or should I be using bass blockers on the the door speaker or can they polk 6.5 run full range with this kind of power? The dash are a polk tweeter mid combo with a built in crossover so that is not an issue. THANKS I AM STUCK ON WHAT TO DO
Adding a amp to stock H/U will sound better, but changing the H/U will give a bigger improvement. If you gonna do the amp,get one with a built in hi/low crossover and skip the bass blockers
