Quick Install Information The Epicenter InDash needs to be installed in the signal path between a source unit and an external amplifier(s). Although it can be installed after an equalizer, it must be installed BEFORE A CROSSOVER. Once this is done, you need to hook up + 12 volt power, -12 volt ground, remote turn-on, and connect the illumination wire. If you need to know more, then read on. Heck, if you don’t think you need to know more, you should still read on, because you can never know too much.
A GUIDED TOUR OF The Epicenter InDash The Front Panel ➊ Bass Restoration Control a.k.a. “The Knob”: This knob controls how much of the restored bass is added to your audio signal. Being that it is a knob, this means you can SLOWLY increase or decrease the amount of processed bass. (Read as: LISTEN FIRST, CRANK SECOND!) ➋ Restoration: By pushing in this switch you engage the bass restoration circuit. ➌ Para-BASS Controls: These two knobs control the Para-BASS equalization functions of The Epicenter InDash.

The Top View ➊ Power Connections: This nifty connector is a godsend to anyone who has tried to wire up their gear with their head crammed under the dash. You can wire up the power, ground, remote turn-on, and illumination from the convenience of the driver’s seat and then casually plug it in the back of your Epicenter InDash. ➋ Outputs: These RCA connectors should be connected to the next component after The Epicenter InDash, such as a crossover, equalizer, or amplifier.
The Story Behind The Epicenter Bass Restoration Technology Now that you have purchased The Epicenter InDash you may ask yourself, “Why would I need to restore bass?” The truth is that during the recording process, low frequency information can be “mixed” down or filtered out during the recording process. It’s not that recording engineers are out to get you; in fact they are looking out for your best interest and are concerned that many speakers systems can not handle “truly” low bass information.
HOW MUCH DO YOU REALLY KNOW ABOUT SPL LEVELS? Before you go out and design yourself a 140 dB plus SPL monster, you might want to consider the following: Nuclear Explosion 200 dB + Airplane Engine take off at 100 feet 140 dB Jack Hammer 130 dB Normal conversation speech 60 dB If you have dreams of rocking around your neighborhood, blowing away Mr. Rogers and all your friends with decibel levels of 160 or higher, you might think twice.
recommended to avoid hot spots like the firewall, engine compartment, or tail pipe.

Figure 10: The Epicenter InDash with EQS and 4-channel source unit Adjusting the Para-BASS Controls The bass response in a system is affected by four factors (1) the acoustics of the vehicle, (2) the location of the speakers, and (3) the music on the tape, CD, or source unit, and (4) amplifiers, speakers and speaker enclosures. Because of the variations in the recording process, we developed The Epicenter InDash to help restore any low frequencies lost during the recording process.
