CSI Custom Boxes

Welcome to CSI Custom Boxes. We are a newly opened business who specializes in creating our own car stereo boxes. We are located in Galva, IA but are willing to ship our boxes anywhere in the continental United States. If you're local, we can also arrange a local pick-up or meet ya somewhere convenient for the both of us. We guarantee you will not find cheaper boxes anywhere!! We can build ported, sealed, bandpass, and even our own custom creations. We can either build a box to your certain specifications or we can give you our own professional reccomendation. All of our boxes start at $55 and go up from there depending on size and difficulty. We guarantee no matter what style of box you want us to build you won't find one cheaper anywhere on the internet or at any other businesses. If so, we would be willing to match that price as long as you have proof. All of our boxes are made of 3/4" MDF Board and are CSI sealed to guarantee the best sound quality possible. Every single box is handmade and we guarantee your satisfaction. We can also install CD players for $20 not including the harness. Full stereo installations start at $75 and include subs, amps, and CD player. If you want us to install a smaller combination then that mentioned above it can be had for the lower price. If you are interested or have any questions please feel free to email us at or call Matt at 712-221-9967 or Devin at 712-301-9207.
