There are several things you can check. Do you have a multi-meter?

My mtx thunder 6500d amp hums when connected light turns on but no output


Make sure you have a proper ground wire connection. The ground wire should be connected solidly to the vehicle chassis in a paint-free location. If it is loose or there is paint t the connection site, you will have problems with the amp output. Also check the speaker wires to see if they are touching the vehicle chassis. This will cause a short circuit and you will not have output from the amp. Finally, check the leads from the head unit. They should be RCA cables, and should have a good connection to the amp.

Can you run two mtx 6500d amps in parallel for more power?


Not suggested to parallel the output of two amps. Instead take each amp, find out what the amps lowest impedance it can drive is and select your speakers based on that. According to MTX these are stable down to 2 ohms without a rated output power of 500Watts X 1. If you get two dual voice coil subwoofers with each coils characteristic impedance of 4 ohms, when you parallel the two coils you will get a 2 ohm load. Just maek sure the speaker can handle the 500 watts.

I have a brand new soundstream xxx 6500d amplifier and when i installed it for the first time protect mode light come on even without rca jacks and speaker wires hooked up. any1 can help?


You need to plug in the RCA and speakers you could blow the amp. The amp is sensing no Input and No output. I would unplug the amp wait around 30 seconds then install the rca and speakers THEN install amp to battery + cable. You should be ok.

Subwoofers won't work and they are brand new


Hello,

I've got a pair of these MTX's subs powered from a Fusion 450 watt 2-channel amp. For the price, they are great. By the way, they are 4-ohm.

My first suspicion would be that something in the first incorrect wiring damaged either the amp or the subs. Can you explain specifically what the "installing the subs incorrectly" means? Was the amp output shorted out at any time or was it operated without a load? Either of these conditions will fry an amp and sometimes, the protection circuitry doesn't work either.

First make sure that your amp is still working. Check both the primary power fuse, usually located near the vehicle battery, and the fuses on both sides of the amp. Make sure that when you turn the system on, the power light comes on steady (blinking is protection mode). Test your subs one at a time on a speaker output.

About 6 months ago i had installed the mtx thunder 6500d amp to run my 2 rockford fosgate power T1 12inch subs and every thing was great untill recently it stop puting out sound it still powers up and...


good morning and welcome to fixya. not a bad setup you have here at all, you ned to start by checking the speaker wires inside the box to the connector inside and then the wires from connector to amp on outside. if everything looks fine there, then you need to check the amp for power out of the rca plugs to make sure the channel is not dead. if you are looking for a new amp you can try several different ones from fosgates new line up to soundstream's. im running 4 polk momo 12's on the tarantula amp and love it. they are great amps. hifonics also has a new line up pretty cool stuff, heard really good things about there stuff to. good luck and let me know so i can help you out.
