Man you do go through some stuff, lol! Nice boxes mang........nice!

 

[oldschoolboomer 10+ year member]

the r's are doing 146 and change just stuck on the floor in the back with no tuning and a less than ideal track playing. this will definitely go up a little. with them in the ported box they were only doing 141. 4th order ftw!!!
