Hey guys

So i installed new speakers in the front doors, but it comes really low sound from them. Im thinking about buying an aftermarket amp and connect the new speaker and tweeters straight to the amp. How is the best way to wire the speakers & tweeters to the amp (in the trunk). Do i need to cut wires from the dash (i got android headunit) or do i need to lay down new wires from the trunk and into the doors?
