I just replaced by front door speakers with 5X7 DB571 speakers. they have a 160 watt peak and a 60 watt continuous power. I may later replace my rear speakers. I also have a 12 Inch sub with a 500/1 JL audio monoblock subwoofer amp so i need to make my high and mids louder to help even out the bass. i have a kenwood exceleron head unit. this is all in an 2002 mazda protege5 hatchback. so could you please recommend a good amp for my door speakers and the best way to install it. thank you.
