Is there a general consensus on using one large amp for the entire system or using multiple amps for multiple components? I have a regular cab Toyota Tacoma, I was looking at running two 8"s behind the seat and a midrange/tweeter compent set in the front. I went to my local audio shop and they suggested I use a 4 channel amp so everything will have equal power. If I use two smaller amps I can build my system in steps. Also, two smaller amps would fit better under the front bucket seats. What do you guys think? Better to use one larger amp or two smaller amps, or does it just come down to personal preference?
