SUGGESTED HOOKUP
This Amplifier is optimized to run into 4 ohm loads
This can be configured many ways:
2 eight ohm woofers @ 350Wrms each
1 four ohm woofer @ 700Wrms each
CONTROLS AND CONNECTORS
Positive Power Terminal - This is the power feed from the positive
(+) terminal of the car’s battery. Use 4 gauge cable and good quality
terminals when routing this connection. Tighten the connections well
to prevent power loss due bad contact. Route the power cable away
from the RCA and speaker cables
Ground Terminal - For optimum performance, an 4 gauge cable
and good quality connectors should attach the this terminal to the
battery’s negative (-) terminal.
Remote Terminal - The amplifier will turn on when 12 volts is
applied to this terminal. This 12 volt signal is usually taken from the
Power Antenna or Remote wire coming from the source unit.
Speaker Terminals – Two pairs of (+) and (-) terminals are provided
for ease of connecting multiple woofers. It does not matter which (+)
or (-) you use as they are connected together internally. Running too
low of a speaker impedance will cause the amplifier to go into a fault
condition.
Lowpass Filter – Linkwitz/Riley 24db slope. This control sets the
6db down point of your amplifier. Higher frequencies beyond this
setting are not heard from your speakers.
Gain – Allows input levels between 150mV and 2.5 volts for full
output.
Inputs – Two RCA jacks are provided. Their signals are added
together inside the amplifier and the bass information is extracted.
Since they are summed together, it does not matter which one is
‘Left’ or ‘Right’.
