I have a 2010 ford focus SE and i do have at this moment two 15" kicker comp running on a 500 watt Alpine amp. This thing bumps and shakes my headlights like crazy. But knowing me i want it louder ( it might be because im going deaf and cant hear it or im not shaking the neighborhood enough) My question is, what can my car handle wattage wise? Im not real smart when it comes to car audio so sorry if i sound stupid. i dont want to mess anything up and i dont want to mess with the wiring ether. As is it, all factory, what can the car handle safely? i was thinking 1000 watts for subs and 500 watt for new door speakers? Would you suggest this or not? i dont want to burn up my alternator or anything else so from what you guys know what would you suggest wattage wise as the safe limit for my ride since i keep the volume up 24/7? Thank you and GOD BLESS!!
