hello. i'm new to audio stuff for cars. i'm plannin on using my stock system on my 00 accord. but i want to add one 12" sub. i wanted to get a truck box cuz it's small and i need the trunk space. does it sound worse than a regular big box? and wat are good name brands for subs and amps? and how many channels and watts do i need? i just want decent bass, not earthquake shaking bass. i was gonna get two 10" subs but it's too much space. any advice would be appreciated. thanks. how much would a total package cost?
