CONTROL FUNCTIONS
1. SPE AKERS
Connect spe akers/sub woofers to th ese termina ls. Be sure t o ch eck wire fo r pr oper
polarity. Never con ne ct the spea ke r cables to c ha ssis grou nd .
2. +12 Volt Power
Connect th is termi na l throug h a FUSE o r C IRCUIT BREAKER t o the pos it ive term inal of
the vehicle b attery or the p ositive ter minal of an iso lated audio s ystem batte ry.
War ning: Alway s p ro tect this po wer cable b y i nstalling a fuse or circ ui t breaker o f t he
appropria te size withi n 18 inches (45 cm) of the batt ery termina l connectio n.
3.Remote Turn On
This t erminal tur ns on th e am pl ifier when ( +)12 v olt is applied to it . Con nect it to the
remote tu rn o n lead of the hea d unit or signa l source.
4.GN D
Connect t his cable d irectly to the f rame of the ve hicle. Ma ke sure the metal fr am e has
been stripped of al l pa int down to the bare m etal. Use the short es t di stance possib le. It is
always a g ood i dea to r eplace the factor y gro un d a t thi s t im e w it h a larg er ca ble e qual to th e
new am plifier power c able o r la rger. C AUTION: Do not conn ec t th is terminal directly to the
vehicle bat tery ground t erminal or an y other facto ry ground poi nts.
5. RCA in put jacks
These RCA in put jacks are f or u se with sourc e un its that ha ve R CA ou tputs. A so urce unit
with a min im um le vel of 200mV is required for proper opera ti on. The use of high quali ty
twisted pa ir cab le s is re co mmended to decre as e the p os sibilit y of radi at ed noi se enterin g the
system.
6. Hig h level input s
The hi gh level i nputs are fo r use with speaker lev el wiring. Some source units do no t
have RC A o utputs, so use t his ter mi nal for speaker level s ig nal inp ut . CAUTI ON : Never use
high level in put when RCA inp uts availab le.
CONTROL FUNCTIONS
7. REM OTE
Connect th e remote controlle r to cont ro l the sub wo ofer amp lifier vol ume from th e driver
seat locati on, for ease of a djustment d uring playi ng.
8. LEV EL Control
The level contr ol wi ll match the amplifi ers sensitiv ity t o t he source units si gn al voltage.
The Operati ng range is 200 mV minimum to 5 V maximum. This is NOT a v olume con tr ol!
9. Low P ass Filter Co ntrol
This con tr ol is use d t o select th e desire d l ow pass x -o ver freq ue ncy. The freque ncy can
be adjusted f rom 40Hz to 220 Hz for all bass m ono models.
10. Su bsonic Filt er Control
This cont ro l can filte r ou t unwante d low frequen cy from 10Hz (O FF) to 50Hz . This
function wi ll increase t he power hand ling of your wo ofers.
11. Bass Boost Level switch
This switc h can boost ba ss level by 0dB, 6dB or 12 dB. Th e b oost fre qu ency is c en tered
at 50Hz.

INSTALLATION PRECAUTIONS
Before you i ns tall t he amp lifier, i nvestig at e yo ur car's layou t very careful ly. Take sp ecial
care w hen yo u wo rk n ea r th e gas tank, fuel lines , hydr aulic lines and electrica l wiri ng. Befo re
making or breakin g po wer connectio ns i n yo ur s ys tem, discon ne ct t he vehicle ba tt ery.
Confirm that yo ur head unit or other eq ui pment is turn ed off while conne cting the input ja cks
and s peaker ter minals. If you n eed t o replac e the power fu se, r eplace it only with a fuse
identical to that sugge sted b y th is m an ual. Using a f use of a different type or rating may result
in damage to yo ur audio syst em or your ampl ifier which i s not covered b y warranty .
MOUNTING AMPLIFIER
1. Pl an th e i nstallati on of the amplifi er s and find a s uitable lo cation with suffi ci ent air
circulati on.
2. Check th e dr awing below t o mount the bot tom amplifi er.

CONNECTING THE AMPLIFIER
1. Select cab le and fuse acc ording to the f ollowing ta ble.
2. Connect the amplifi ers ground c able to a close, ba re me tal part of the frame or
chassis. U se a nut an d bolt , NOT a s crew! Th e grou nd cab le must be at lea st the same s ize
as the +12vol t cable.
3. Connect th e re mote termin al to remot e ou tput of the head un it using 16 gauge (or
heavier) wi re.
4. Connect the fuse holder within 18”(45c m) of th e car batter y, an d run the s elected
cable from th is fuse to th e am plifier.
5. Connect all the i np uts with h igh-quali ty cables. C onnect Rem ot e Control if
necessary.
6. Insert f us e(s) into t he b attery fu se h older(s).
7. If using a subwoo fe r for 2-CH an d 4- CH, bridg e th e channel s by u sing the Le ft “ +”
and the Right “ -“ terminal s.
