1) The amplifier heatsink end should be facing out. 2) Ideally there should be several inches clearance between the amplifier heatsink and the seat or surface it is backed up to. Make sure the open port beside the woofer is not obstructed. 3) When all connections are made the final step should be to secure the enclosure using the mounting brackets provided so it remains securely in place. WARNING: Make sure where ever you choose to place the enclosure it’s a dry location on a solid surface.

LOW INPUT (RCA) Jacks These RCA style input jacks are for use with source units that have RCA line level inputs. A source unit with a minimum output of 100mV is required for proper operation. However, this input can accept levels up to 6Vrms. 2.
5. PHASE Switch This switch will reverse the phase of the speaker output without having to touch any wiring. 0 is normal. 180 reverses the output. Select whichever setting provides the most bass. 6. LPF (Low Pass Filter) Control This filter allows the low pass of frequency and has an adjustable crossover point from 50Hz to 200Hz. A setting of 50Hz will produce only the low frequencies (deep bass). A max setting of 200Hz will allow the amplifier to produce a more punchy (higher) bass response. 7.
POWER WIRING AND SIGNAL CONNECTIONS POWER CONNECTION BATT+ The amplifier should be wired directly to the vehicle battery using a 8ga power cable. Start at the vehicle battery and run the power cable through the vehicle’s firewall using grommets to the amplifier’s BATT + screw terminal. If factory grommets are not available install grommets yourself to protect the cable from sharp metal edges. Avoid running the power cable over the engine components and near heater cores.
INPUT SIGNAL (CHOOSING THE HIGH OR LOW INPUTS) The PS-AWB amplifer control panel input signal connects to the head unit’s High Level (speaker wire) output OR Low Level (RCA) output—provided the radio is so equipped with Line Out. A dedicated subwoofer or low level signal will deliver the best performance. If unavailable use the high level inputs, as will be the case with most factory head units.

Low Level Input and RCA Interconnect Wiring (fig 5) For radios that have RCA line outputs. You will need to connect the low-level RCA style inputs from the PSAWB to the line-outputs from the radio (source) via an RCA interconnect commonly called a “stereo patch cord”. Choose the correct length and style of RCA interconnects for your needs.

SET UP ADJUSTMENTS Your PS-AWB enclosure uses several controls to provide sonic integration with virtually any vehicles unique acoustic properties. Please read the following section carefully to familiarize yourself with the function of each control. The following adjustment sequence is recommended to properly tune your PS-AWB enclosure. By first adjusting the GAIN, the LPF, then the PHASE switch, followed by the BASS EQ (in this order) will give you the best results. GAIN MIN MAX Fig.
SWITCH POSITION PHASE Fig.8 PHASE Switch Setting the PHASE switch Start with the PHASE switch set at 0˚ and play a favorite music track that contains some solid bass (make sure the BASS EQ control is set at the 12 o’clock position). Then flip the switch to 180˚ and listen to the same musical track again. Choose the setting that provides the best bass response according to your taste. BASS EQ □ dB 12dB Fig.
Fig.10 Connection with RJ45 Jack Remote Level Controller Your PowerBass PS-AWB enclosure includes a wired Remote Level Subwoofer control module. It uses standard telephone wire and telephone RJ45 connectors. To connect the Remote Subwoofer Gain control to the amplified enclosure, simply insert one end of the telephone plug into the REMOTE gain port. Plug the other end into the back of the remote module. Mount the module within easy reach or under your dash.
