I have a 05 crew cab Silverado with 2 DVC 2OHM kicker comp rt. Shallow mounts wired to 2OHM to the kicker cxa1800.1 mono block amp. Im wanting more bass. Should I add another kicker or just go with more powerful shallow mounts? I see the JL TW5 but are they with the price? Ive also looked into the Rockford Fosgate T1 shallow mounts. What would be the most powerful system that I can suff in my truck?
