|CS84SV in .75 Cu Ft Ported @ 300Watts, 35 Hz|
Here is a system that offers extended low bass in a very cost effective package. Budget audiophiles should love this one! By tuning the port "low" and taking advantage of your vehicle's natural low frequency boost, solid bass down to 30 Hz is obtained. Use a 2.5" I.D. port 12 3/4" long or, if you can work it in, a 3" port 18 3/4" long (would probably have to be an external port). For full power handling, use a sharp High Pass filter at 30 Hz.
