If the amp produces no boom with no signal input cables connected, I'd suggest using an LOC.

Let me know if you have any other questions.

My mtx thunder 421d I just got has the red light staying on all the time, I have hooked up a rca converter and the amp wont play my sub, is that light supposed to be red all the time.


The LED should be red. If you are not getting power to the sub, make sure the speakers are connected properly to the amp. Also make sure that the gain control is turned up. If it is all the way down, you will not hear anything from the sub(s). If none of that works, it is possible that you have a blown sub. If you smell a burnt smell near the speaker magnet, there is damage to the voice coil in the sub.

Need to know how to wire my system ...I have the infinity reference series 611a I was told it was a mono block but it has two channels on the exterrior...also I have two 12 inch MTX thunder dual voice coil...


it all depends on what kind of box the mtx subs are in as far as wiring the subs. The best way would be take the speaker wire from both sub boxes and run the positive into the right positive then the negative into the left negative. and run 8 gauge wiring kit to the amp because 10 might be to small and 4 is to big 8 gauge is perfect for this amp.

How do i wire a mtx 251d at a 2 ohm load


To wire up a 2 ohm load depends on the subs. You will either need 1 sub rated at 2 ohms or 2 subs at 4 ohms wired in parallel. This website will help.
http://www.the12volt.com/caraudio/woofer_configurations.asp?Q=2&I=41#results
You can also use 1 dual voice coil sub rated at 4 ohms wiring the same way you would the 2subs at 4 ohms. Good Luck

Can you help with my wiring?


The more amp you are pushing the better. Better too much amp then not enough. How many watts per speaker? less then the amp I hope. When you need decibles the more air you push the louder it will be. Enclose in a MDFB enclosure or plexiglass and feed towards each other and port the box to the sides. This will cause some annoyance. We ran 2 rockforts @1000 watts and abtained 137dc before the back windshield blow out,,lol

WIRING A DUAL VOICE COIL SUB.


Just wire one voice coil each into left and right rear respectively, in series with the original rears or if this is too quiet, wire both voice coils in parallel together and connect as per original single coil unit.

As they are 4ohms each they can simply be connected as simple speakers on each rear channel output, since thats exactly what they are, capacitors are used inside to make them react to bass frequencies only. Wiring them up is no different to wiring up a pair of 6x9's.

My red light on my amp is on and wont go out


Unfortunately I think you need to get it repaired or replaced .When a protection light will not turn off it is generally caused by an internal short and needs one or more replacement parts for it to come alive again.

Infinity 1600a cuts out wit real low bass when turned up load



With your multimeter set to DC volts, the black meter lead on the ground terminal of the amp (not on the point where the ground wire connected to the vehicle), touch the red lead alternately to the B+ and remote terminals of the amp. If the voltage drops below ~11 volts on either terminal when you drive the amp hard, you need to check the wiring feeding whichever line is dropping too low.

Mtx 1501D


if your power light is on then check your preamps (sub out from head-unit).Maybe you need to turn on that output thru head unit's audio menu.Also when using dual voice coils if you wire them out of phase there will be no output

Help! Amp not turning on


Im sorry to have to inform you my friend, if you saw smoke, you burned one or more of the resistors or output devices inside the amp. Without a service manual, it will be a hard call on what exactly cooked. In alot of cases please forgive me for saying so, but the ampis not worth taking into a repair shop to be repaired, because of the high cost these days of labor. Its too bad there are no user replacable parts inside of these amps. Good Luck. Ps Please do not forget to rate this thread?
