Im using 2 10 and a 12 because i want real punchy bass out of my 10" and some deeper bass out of my 12" i originally wanted to use 2 12" and 1 15" but due to llack of space in my Jeep i downgraded in size.
ok im going to run 2 Kicker KX1200.1 amps with 1 Kicker Solo-Baric 04S15L7 15" sub and 2 Kicker Solo-Baric L5 05S12L54 12" Subs in a 1998 Jeep Cherokee with stock power supply.
