The UPA224 andUPA424 require a minimum of 16-gauge wire. The speaker wiring diagrams illustrate options for connecting two or four speakers. When installing or connecting full-range speakers, you must observe the proper speaker polarity. 5 INPUT WIRING & CONTROLS Low Level Input (LOW-INPUT) Low level ( RCA) input is preferred for best performance. Most trunk/hatchback installations require a 15- 20 foot RCA cable, while pickup trucks and under- seat mounting require a 6-12 foot RCA cable. Connect an RCA cable from your receiver to the RCA input on your amplifier. Input Level (LEVEL) The input level control matches the radio output to the amplifier input. After installation, turn the input level control all the way to the left, then insert a tape or CD. Make sure the bass and treble or EQ settings are flat, then turn the volume up slowly until you hear distortion. Turn the volume down slightly. To match the amplifier input, slowly increase the amplifier input level control (turn clockwise) until you hear distortion, then turn it down slightly. After completing this process, your amplifier levels will be matched. High Level Input (HIGH LEVEL) High level input should be used when an RCA output is not available from the receiver.

Connect the speaker outputs from the receiver to the high level input connector, then plug the connector( s) into the “HIGH INPUT” outlet(s) on the end of the amplifier.

UPA224/UPA424 TESTING/TROUBLESHOOTING . Before finishing the installation, perform the Troubleshooting following tests to make sure the wiring is correct and everything is operating properly. Reconnect Battery When wiring is complete, reconnect the battery negative terminal. Test Power Wiring Turn on the receiver, but do not turn up the volume. The amplifier power light should come on. If not, check the REM and +12V wires. Turn up the receiver volume slightly. All speakers should operate. If not, check wiring connections at amplifier and speakers. Test Speaker Connections These tests make sure the speakers are connected properly. If speakers don’t play at all, one (or both) speaker wires may be disconnected. Problem Possible Cause Corrective Action Amplifier does not turn on No power to +12V terminal Check fuse( s) No power to REM terminal Check head unit fuse(s) and wiring Blown main fuse at battery Replace fuse and identify cause of failure Blown fuse at amplifier Replace fuse and identify cause of failure Faulty ground Reground main power ground to bare metal chassis Volume control too sensitive Input level control adjusted too high Readjust the input level Distorted sound Input level control adjusted too high Readjust the input level Blows fuse(s) at amp Power wires connected backwards Reconnect power wires properly Internal problem with amp Take unit for service Engine noise / Alternator whine Ground loop(s) Use good quality shielded RCA cables Faulty ground at amp Reground amp to clean bare metal chassis Faulty ground at head unit Reground head unit to clean bare metal chassis Inductive coupling Reroute RCA and/ or speaker wires away from factory harnesses Input level on amp set too high Readjust input level Poor bass response Speakers out of phase Check speaker polarity; reverse the connection to one speaker only if two subwoofers are connected to the amplifier. 7 SPECIFICATIONS CEA Power Ratings UPA224 Power Output: 18 watts RMS X 2 channels into 4-ohms @ < 1% THD+ N Signal to Noise Ratio: 70dBA below reference (Reference: 1 watt, 4-ohms) Dynamic Power: 44 watts, all channels driven into 4-ohms @ < 1% THD+ N Frequency Response: 20Hz to 20kHz, -3dB (Reference: 1 watt) Dimensions: 230mm X 52mm X 130mm Specifications subject to change without notice.
