Roadmaster-Build

Like the low bass, working on a 95 Buick roadmaster. Was a technician for about 5-6years, worked at dealership mostly. Different job now but still same interests. Had several system over the years nothing big like completion wise, some 10s, 12s, 15s basic setups. Looking to go big with my roadmaster maybe a X15 sundown or a PSI 15 undecided yet, currently have an alpine 1043d type x going in the car mean while. Can’t use the car without the bass. Just looking to learn some more on here and help with what I can.
