When the amp is hooked up it plays for a while then the voice lowwers down


Its probabley getting too hot and/or a fuse is being tripped reducing the power use untill it cools enough to come back on. ??
Does it come back on by itself? Where is the amp mounted? is there enough cool air flow reaching it? Is the proper sterio interface matched up with the max outputs and inputes? deck could be running too much juice to the amp. a bigger amp could help but try re mounting it in a location that allows for cool air flow to keep it cool. if you were running a sub woofer i bet the bass would cut out...what kind of speakers are you running with that amp and what kind of deck...it all has to be compatable with eachothers power outputs etc.

My subwoofer doesn't receive power, all amp fuses are fine, amp powers on, remote wire and rca wires are connected and intact. Before it stopped working all together the woofer would cut out and after...


If you are getting power to the amp, try this....Find a small speaker, unhook your sub and wire speaker to amp. Turn on your system at a low volume....If the other speaker is playing through amp, then your sub is shot.....If the small speaker doesnt work, then its either your channel is gone on the amp or the rcas have quit off off your head unit.

If your voice cuts off when you use too much power i.e. operating power windows you are taking power away from your amp. An amp operates in stages; therefore you must increase the available (battery) power in your vehicle; possibly you can run two batteries (do not connect them in series)

alot of times its not just the amp that gives you better sounding bass.. A lot has a to do with a few other factors as well.. first off your subwoofer.. the bigger the subwoofer the deeper the bass. Some woofers exturde, or flex differently depending on the quality and structure of the woofer.. 2nd is gonna be the sub box. different size boxes will give your sub diff. depths of bass. ... general idea is the bigger the box deeper the bass. But if your woofer is not supplied enough power a big box is useless.   With that size amp your best bet is too run a single woofer. Probably a 10inch woofer would sound the best.. but it in.75cub inch. sealed box.. should sound great.

Amp cuts out and back on 30 or so seconds!! Volume has no impact


You need to check the B+ and remote voltage on the amp when it cuts off (assuming that you can recreate the fault).

With your multimeter set to DC volts and the black meter lead on the ground terminal of the amp, touch the red lead alternately to the B+ and remote terminals as the amp shuts down. If the voltage drops below ~11 volts, you need to check the wiring feeding whichever line is dropping too low.

Amp cuts off


You may have a problem with the power source feeding the amp. You need to check the voltage across the amplifier's B+ and ground terminals when the amp is playing/cutting off. If it's dropping below ~11 volts, you need to determine why it's dropping so low.
