SUGGESTED HOOKUP

This Amplifier is optimized to run into 1/2 ohm loads

This can be configured many ways:

8 four ohm woofers @ 275Wrms each
6 three ohm woofers @ 367Wrms each
4 two ohm woofers @ 550Wrms each
2 one ohm woofers @ 1100Wrms each

ONTROLS 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 - Connect to speakers using 8 gauge wire. The
8 gauge wire can be run to a distribution block to allow connecting
multiple woofers. 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’.
