I have a dub audio

Despite the fact that they claim that the amplifier is 500 watt RMS if you look at the fuse it has on it, which should be one 30Amp fuse it means that the max that you might get out of this amplifier is 300 watt RMS. So an 8 Gauge cable will be more than enough for it. However, saying that, using a 4 gauge cable will not harm it in any way. what you should check before buying a 4 gauge cable is if it will actually fit in the allocated 12V terminal.

I have a dub2502 amp with the red protection light

The unit will need to be repaired by a technician. Most likely you have a bad transistor that is causing the protect mode to turn on. The only way to get the protect mode to turn off is to remove the bad part.

One sub is not playing and when is wired to the

from how i understand you statement, and your subs are connected in a bridged fashion, then i advise a word of caution, as i believe that you may be imposing a serious load on your amplifier. the sub that is not playing may in fact be shorted and that is why it cuts the signal to the other sub. the amplifier sees both subs and the shorted one will impose a serious load and can cause the amplifier to fail if driven hard. separate the subs and meter them with an ohm-meter and see if they are close to the same. if they are 4 ohm for example, they might read around 3.2 ohms, etc. using a dc ohm-meter is not an accurate to measure the impedance of the sub, but it is accurate for comparing two subs. you will probably find that the one that is out is shorted and will read below one ohm. everything that i have stated so for, takes into account that your subs are bridged to the amplifier. if in fact they are not bridged and on separate channels, then swap the subs around and if the bad one starts playing, then you have a bad channel on the amplifier or a bad input to the amp lifer. at this point you would swap the rca inputs around and if the bad sub that started playing when you swapped it around, goes out again, then it is an input problem which then you should check the rca cable or radio itself. i know my statement may be a little confusing, but if you follow them exactly, you should be able to determine exactly what is at fault. let me know if you need further assistance....v

you have your speakers hooked up inproperly the amp is going into protection because you are presenting it an ohm load lower than it is able to operate at... go to www.the12volt.com and go to the subwoofer wiring diagram section and you can go over your options...

The indicator light on the amp is staying red in

Check your manual, sometimes you have to take it back in, depending on the protection. Sometimes you have to change up the fuse. Is there enough power going to the amp, or to much?

Kicker amp goes into protection mode as soon as i

Have you tried powering on without speakers connected? Have you tried powering on with no input? If either senerio causes the amp to NOT go into protection mode, then there is most likely a short in wiring. Use a multi meter to isolate.

DUB 2502 Protection Mode help

The most common reason for an amp to go into or remain in protect mode is shorted output transistors. To eliminate other possible causes, read through the following page. Let me know if you have any other questions.

Amp stuck in protection mode, help!!

for 1 the amp is no where close to strong enough for the subs and 2 if the amp is mounted on the box it is vibrating the electronics loose. you always want the amps rms power to be be about 25% more than the speakers rms rating, from the sound of it you are either undriving the amp (clipping) or running the amp at 1 ohm load which is making it burn up. if the amp gets hot (which class d amps should never ever do) then try running just 1 sub. if the problem goes away then you know the amp is not enough for the subs. try a hifonics amp you will be amazed at the quality and power difference. I sell all major brands cheaper than almost anywhere. let me know the exact model of the subs and i can recommend a better amp for you.

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.
