@teamht I built the box right from every measurement outta the owners manual (with 3/4 inch mdfb) id say on almost every cut has got to be with in a 1/16 or 1/32 or the box wouldn't of went together. Im not a professional but I did run everything in my car so I wouldn't say im a complete idiot about car audio I got my figures just about the amp rms cause hifonics amps are a lil over rated but there still not to bad either
