I got a mtx jackhammer 2400 watt amp. when i hooked it all up and turned it on i am just getting 12 volt on the speaker output wires and no sound. it is just compressing the speakers and that is it. any ideas. am i wiring it up wrong or what. it is bran new.

is amp getting power or not could be wires came loose inside speaker box

A 20 Amp breaker will support 2400 Watts with a 120 Volt line.

120 Volts times 20 Amps (Amperes) = 2400 Watts.

Answer? 24 100Watt light bulbs.

HOWEVER, you should always allow 1 cushion of 100 Watts.
That would be 23 100Watt light bulbs.

(Wait until you add electric motors to the equation. Things start getting a little more complicated)

(I always use 20 amp breakers for lighting. 15 amp breakers for lighting is phased out.

Secondly a 20 amp breaker requires using 12-2 or 12-3 wiring. (12/2, 12/3)
SO does the receptacles.
Therefore 12 gauge wiring is used throughout the house, until you come to the heavier loads )

[ 12/2 = 2 insulated conductors, and one bare copper ground wire.
12/3 = 3 insulated conductors, and one bare copper ground wire.

Remember, with 12/2 the Black wire is ALWAYS the Hot wire. White is Common (Neutral). Bare copper is Ground wire.

12/3 has 3 conducting wires.
One Black, one Red, and one White for the Common. (Neutral) Bare copper is Ground.
Used for 3-way switches ]

re-word can't understand

It sounds like you have constant 12volts applied to your remote turn on lead. The amplifier will have 3 connections for power:

1. 12volt constant
2. chassis ground
3. 12volt switched power - this wire should come directly from your head unit. It only sends 12 volts when the radio is on allowing to amp to power up only when the radio is on.

im not sure what is wrong but i do know if you keep it hooked to subs it will fry them because that happened to my friends jackhammer amp and 2 12" mtx jackhammers

this is a signal crash either your speaker wires are crossed (wrong wiring phase) or your RCA jacks need replacing also it could be inside your amp the solder lines may have fused. If after checking and replacing wiring problem persists return to MTX for repair.

Is the box sealed air tight, leaking around speaker? plumbers putty works great. Amp may be good enough for the mtx but underpowered for the kicker. When kicker says 1000 watts that what it is (at a 14.4 volt input). Mtx is ok but may not tell the true watts. Check to see if the speakers are the same ohms also!

i have seen the jackhammer at autobarn moss street slacks creek brisbane qld not sure if it is 12000 watts but looks massive you could also try gold coast car sound brisbane qld

That's not a 1000w amp. It's a 400 watt amp when loaded to it's lowest rated load. If you have one speaker per channel (the only safe load if you have single 4 ohm coil speakers), you're only getting 165 watts/speaker. It's probably distorted because you're driving it to clipping.

Hi jimmyjames,

 

How do you have the wires hooked from the sony reciever to the inputs on the mtx? 

 Sounds like your Remote wire is way too big. it should be 14 guage.  It only sends a low voltage low amp signal.

 

Another thing that could be messing up the sounds is the routing of the wires.  you should have the power supply wires separate from the Audiop signal wiring.  Power should run down the Driver side and Audio down the passenger side.

 

When you answer I may be able to tell you more.
