Bass Driver: The HDBR contains a Bass Driver circuit that accurately recreates and injects 
Low Frequency information back into the signal path. What that means in everyday terms is 
that the HDBR will give more bass impact to your best compact discs or lowest quality 
recordings.

Bass Equalization Circuit: The HDBR has a unique equalization circuit that contours the 
restored bass to your speaker systems.

Dash Mount Remote Control: The HDBR comes with a Dash Mountable Remote Control 
that allows you to enjoy the effects of the HDBR without having to leave the drivers seat. The 
Dash mount Control has an LED indicator that will grow brighter as you add more bass or 
dimmer when you decrease it.

Bass Maxximizer Indicator: Not only does the HDBR provide good music to your ears, but 
it also gives you some visual enjoyment as well. On the chassis of the HDBR there are three 
LED indicators that flash when the bass maxximization circuit is activated.

Bass Output Control: The HDBR has the ability to produce large amounts of deep, ear 
blowing bass without damaging your speakers. The Bass Output Control circuit allow the 
HDBR to maxximize the bass output of any autosound audio system while restraining 
destructive bursts.
