I recently bought a 12 inch reaudio sx series subwoofer with a us amps 12.1 amp..both stable at 1 ohm...I hooked it up running it with 2 1 fared caps...and it is cutting out when there's lot of bass...I haven upgraded the battery...all I have done is run 4gauge wire with a 100 amp fuse...also the amp is on low settings..any idea why it is doing this
sounds like the amp is drawing too much power and your electrical system cannot handle the load. what exactly do you mean by "the amp is on low settings"? that tells us nothing.
it is fine with the gain all the way down, as soon as I turn it up like half way, it will go into protection mode even at 14.0v. Now im thinking i might have wired it wrong
Well it could be a couple different things going on. First off the gain on the amp is only need to get an extra bit of boost out of the amp after you are done tuning.
Where is your amp ground at? Is the paint sanded off the metal? are you using minimum 4ga like your power wire?
You could also have a bad amp(s) or a bad sub. Subs can be blown and still work and so can amps.
When it comes to electronics you always have to remember that your power wire means nothing if you have a shitty ground. The flow of electrons go in through the ground wire and out through the power. Having a bad ground can cause your amp to cut out at higher volumes and letting this happen coninuously will end up putting your amp up in smoke in the long run.
i would ohm out the subs and also check the way they are wired... from the sub to the box to the amp etc... good luck

i had this problem before...my ended up being that the amp was over heating cause i had it on the back of the seat and then the speakers went up against it so there was no room in between. If thats how ur is try puttin on top of the box or something and let the amp breath a little!

/sigh. come on 04 you know better than that. the gain on the amp is to used to match the input it receives not to get an 'extra boost' of power.
to the op, do as suggested - check the ohm load your sub is showing to the amp. check all your grounds. actually check all your connections.

Damn you beat me to it
seriously what kinda response is that "the gain is used to get extra OOmph???
seriously man
I understand you want to help but steering people in the wrong direction and/or giving bad advice does more harm than good

i had the same prob in my car i ran a rockford t1500bd with 2 t1 12s in a 2 ohm, 1/0 gauge stinger wire with the big three and a optima yellow top. im not sure if it was the subs or not but i switched to 2 fi ssd 10s on 2 ohm. it hasn't cut out yet and my volt gauge doesnt drop as much as it did check the impedance and see if its the amp or subs like said before. by chance does ur deck cut out to or just subs/amp
Ok let me rephrase that then. Normally when i am setting up a system i will take the bass boost or Punch EQ on a RF when the remote knob or other bass knob is being used and make sure i have it pinned because obviously every 16 year old kid coming in is going to be pinning it 24/7. Yes i know the gain is for matching so you don't get nothing but bass when you crank that bass knob or the sub gain on the deck. Once the gain is set by the person that has tuned the system then it should never need to be touched again. Getting that extra oomph is done with the remote bass knob or the sub gain on the deck.
I apologize i was backwards on my previous statement.
the amp goes intp protection mode, when it does cut out it does not feel hot at all. the sub i have is a 2 ohm dvc....i know it is possible to wire it in 1ohm and 4ohm...but is there any way to leave it 2 ohm, by separating each voice coil. the amp i have have 2 channels. could i just take 1 wire from 1 voice coil to one channel in the amp and do the same for the other voice coil. or should i just tr running it in 4ohm

Using the remote bass knob is a big no no unless you like poor sound quality. Most are set at a bad frequency and can sometimes induce sub clipping.
