Beckett Posted November 11, 2008 Report Share Posted November 11, 2008 I've heard about this before but i can't remember....why doe sthe bass seem/sound louder when you have the windows down compared to a sealed car? If i was to have 2 Alpine Type-R's at 550ish RMS a piece would that be louder and shake my head more than my single R at 1100RMS? (only on -7 bass) if i was to ground my 2 amps to the battery in the boot would that be better than to the chassis in the boot? (battery has 2 runs front to rear btw) Thanks JS Fraser *Alpine Typr-R 12" *JBL GTO 1200.1 Sub Amp *Alpine PDX-4.100 *Rockford Fosgate Power 6.5's *Rockford Fosgate Fanatics 6.5's Both in front doors *0/1 Guage wiring from front Junction Boxes to 120AH Battery In Boot (battery removed because too small for alternator) *140 Amp HO Alternator *Alpine Head Unit -------------------------------------------------------------------------x------------------------------------------------------------------------------ Link to comment Share on other sites More sharing options...
finkster Posted November 11, 2008 Report Share Posted November 11, 2008 Yes it does sound louder most of the time.... Think about it this way...If you stick your ear in the port of a box it gets pretty loud, right? Well think of the window being another port for air pressure to escape out of the car.... And nothing beats a ground at the FRAME, not the chasis. hope this helps.

Mosin Posted November 12, 2008 Report Share Posted November 12, 2008 IMO there are alot of variables when it comes to window down/up. I mean some can be louder up, vice-versa... The 2 Type-R's should be louder than a single 'R' if they are both in ported boxes and such. I believe there are to many variables for it though. I've seen single woofers get louder then multiple woofers. Not talking about burping/SPL either. Derp. Link to comment Share on other sites More sharing options...
