installing aftermarket stereo system
this is a 2 part question. i own a 2015 compass
1. my wife bought me 2 sets of alpine 6x9's for the doors and after popping off the grilles on the door i notice the factory speakers have a square plug adapter whereas the alpines do not. can i simply cut off the adapter and splice on the standard speaker wires/connectors that came with the alpines?
2. the alpine speakers are 3-way 400 watt speakers. will this force me to buy a new head unit or will the new speakers work/sound good with the factory head unit?
