Hello everyone. I am new to caco. I have been a member on ROE for a year or so. Figured I would become a member here as well. Right now I am running a single 15 in 3.5 cubes tuned to 33hz. It started life as a Treo ssi12.22, but it was sent to PSI and rebuilt. I run the Hifonics zxi60.4+1k. I am planning on selling this setup and upgrading, but I am undecided on what to go with. If anyone has ideas or suggestions, I am open minded. I am thinking 2 10's or 12's, and more power. I believe i have just over 4.5 cubes of internal workable space before displacement. My budget will be limited to what I make from selling the current setup, so I'll probably start with 1 sub for now and get the other once I get another job.
