Question about MTX RT2200 Car Audio Amplifier

1 Answer

Constant sound from subs

I have an old MTX RT2200 amp powering 2 10" kicker comps.  When I plug the RCA cables are in and the you move either the gain or the bass knobs up, the subs just start pounding, Not with the music or anything, just pounding. When you turn the gain down, the pounding stops and the subs just barely output music.  When you pull the RCA Cables out the pounding stops and the amp doesn't do anything when you mess with the gain and bass knobs.  I don't know if its the amp or the head unit. Any suggestions on figuring out what it is, or solutions?
PS that RCA Cable is brand new.

Amp and sub have been working great together then all of a sudden the amp is not putting out enough power to push the sub. MTX Thunder 311D


check to see if one of the RCA cables is unplugged or bad. check the gain check the sub level control on the deck if yours has one.

Subs dont beat like they should


you've spent alot of money on **** by the sounds of it!!. you should only ever run multiple subs the same brand, power and resistance you can just connect any old subs to a system you need to wire them depending on the load that the amp needs to see. first thing is to try the amp/s on a individual sub to check your amps still work once done check the subs 1 by 1.

THUNDER 5601 WHEN VEHICLE TURNED ON, SUBS BOOM, THEN WORKS OK. ALSO WHEN RADIO TURNED OFF


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.

Mtx 895 trouble


check your fuse up front first. some amps will turn the light on with only the remote wire (the 12 volt signal from the head unit). That may be your issue. If not you need to check your signal input. try hooking the rca's to a diffrent source, i.e. other radio your tv anything with Rca out put. If still you get nothing then pull your subs out and take a regular 9 volt battery and touch the leads to the positive and negative of the sub. Just for a moment though if the subs move when they come in contact with the charge from the battery then my last suggestion would be to take it to a store where you can have an authorized tech check out the equiptment. Good luck

hi, your amp seems to be getting power but the cables might be wrong so it's not getting enough power. the light on the amp should be green if everything is going well. are you sure the cables are suitable for your amp?

Subs will go off the wall with bass, but not in tune with music.


hi, first disconnect the rca input, then switch on headunit and if the amp produces a constant bass thump it then means it has an internal fault. if the amp idles quietly then replace the rca cable, or try connecting the headunit lineout feed directly to the bass amp, in this way you cud find out if your fault is coming from the headunit or the equaliser. cheers
