j brower Unregistered guest | I have two twleves right now, but I know very little about what box size and amp to use for my new woofers. I am making my own box. Im not sure whether to make it sealed, or ported. actually, i dont even know what they mean. My woofers are 125rms/250 watts total, and 4 ohm. What is rms? and what size amp should I use? Should I wire in series or parallel? I have my wood cut for my box. It is 31"x22"x16". Is that ok for all four? Please any suggestions are greatly appreciated. Thanks, Jeff |
