[QUOTE="Ed Lester, post: 4432007, member: 587479"] I say leave the sensor on the windshield but you dont have to be exact with measurement. Engine running for all classes but limit them to rev to 2000-3000 RPM for safety. Let them play whatever they want. Tones/music, CDs. IPODs, whatever. Cars sealed because if they dont fully understand SPL, Opening windows and doors can hurt SPL and/or damage subs. Clssification, define wall classes. If the enclosure is too high is it a wall? dB Drag's limit is the window line. NSPL is very relaxed and common sense says if its only a few inches above the window line, its not a wall. Amp limits, you dont want a 40,000 watt system going against a 1,000 watt system. Sub limit. 1-2 subs shouldnt go against 8-12 subs [/QUOTE]
