OWNER’S MANUAL 

Troubleshooting 

Problem 

Possible Cause(s) 

Solution 

Power LED off 

No (or poor) power, remote or 
ground connections 
 
Blown fuse 

Verify connections both at amplifier and 
at other ends 
 
Replace Fuse 

No Output 
(Power LED on) 

Speakers not connected 
 
 
Gain down on either amplifier 
or source unit 
 
Speaker(s) blown 
 
 
Faulty RCA leads 

Verify speaker connections at amplifier, 
and also at the speakers 
 
Verify gain/eq controls 
 
 
Disconnect speakers one at a time to 
pinpoint defective speaker 
 
Replace RCA leads 

No Output 
(Protect LED on) 

Amplifier is overheated 
 
Vehicle’s battery is supplying 
something other than 12V 

Review mounting position and conditions 
 
Check vehicle’s battery and charging 
system 

Distorted output 

Source unit/amplifier gain set 
too high 
 
Source unit is not capable of 
good audio reproduction 
 
Speaker(s) blown 

Re-calibrate amplifier with source unit 
 
 
Replace/upgrade source unit 
 
 
Disconnect speakers one at a time to 
pinpoint defective speaker 

Bass is weak 

Dual voice coils on subwoofer 
wired out of phase 
 
Bad speaker connections 
 
 
Subwoofers connected out of 
phase 
 
Eq settings are reducing bass 
power 
 
 
Poor quality subwoofer(s) 
 
Enclosure too small for 
subwoofer 

Try swapping over + and – on one of the 
voice coil connections 
 
Check speaker connections at subwoofer 
and amplifier ends 
 
Check the + and – connections all match, 
swap to test 
 
Verify all eq settings on amplifier and 
source unit, especially “subsonic” and 
“LPF” settings on amplifier 
 
Use TL-1121 subwoofer(s) 
 
Increase enclosure size 

Blowing fuses 

Excessive output levels 

Lower gain 

Amplifier switches 
on and off 

No (or poor) power, remote or 
ground connections 
 
Low voltage from battery 

Verify connections both at amplifier and 
at other ends 
 
Test battery, replace if necessary

Safety 

Health Warning

  

The Competition Pro range of car audio is built for very high power handling.  Listening to 
music at such high powers is potentially capable of causing physical side effects such as 
nausea or even permanent side effects such as hearing loss.  It is therefore absolutely 
essential that conservatism and a high sense of judgement are observed when in 
operation. 
TheLoudest.com accepts no liability for hearing disorders, nausea or other side effects 
caused by this equipment. 
 

General Safety 

Playing loud music in a vehicle can hinder your sense of what is going on around you on 
the road, including your ability to hear your own, and other vehicles.  We recommend 
listening at low or moderate levels while driving. 
TheLoudest.com accepts no liability for injury, property damage or otherwise resulting 
from the use or misuse of this equipment. 
 
Do not use any chemicals when cleaning this equipment.  Please use a clean dry cloth. 
 
Do not install this unit outside the car, or anywhere where it could become damp or humid, 
or where it can become exposed to the sun.  It should be installed in a dry and ventilated 
area inside the car. 
 
Never connect or disconnect speakers when the amplifier is on; this can permanently 
damage the speakers.  Always do this when it is off. 
 
Never open the amplifier up.  Doing so would put you at risk of an electric shock.  None of 
the internal parts are serviceable by the user.  In the case of the unit needing repair or 
maintenance, please take it to a qualified professional. 

For both amplifiers, the power, ground and remote connections are all installed as usual.  
One amplifier is named the master.  This amplifier receives signal in the form of an RCA 
lead from the source unit.  A single RCA lead is then used to connect the “bridge out” of 
the master amplifier to the “bridge in” of the slave amplifier.  All settings the user applies 
to the master amplifier will automatically be sent to the slave amplifier, so there is no need 
to change any settings on the slave amplifier. 
 
When connecting the subwoofer(s), connect the negative speaker terminals of the two 
amplifiers together, then the positive terminal of the master amplifier acts as a positive, 
and the positive terminal of the slave amplifier acts as a negative.  The minimum load 
when using two TL-1023 amplifiers together in bridge is 2 ohm. 
 
It is advisable to use two TL-1191 wiring kits for installing two TL-1023 amplifiers.
