I have a 2002 S-10 2 door Blazer.  Right now i have a pioneer slim sub and box built to fit behind a reg cab s10. Well the 12 is going bye bye to a fellow truck club memeber and i want to have the best of both worlds. 1. Bass 2. Space (cargo) So my question is, what is the smallest box i can go for a rl-i8??? Also will this amp be suffecient?
