Should Amp RMS Match Sub RMS?
Okay I have a one 12 inch sub. It's kenwood, however i don't kno what the watts are or rms since there's no model info or number on it. But i think i might take apart the box and check. So from what I have learnt, the rms should be roughly about the subwoofer rms. Also Im planning on to buy a MTX Thunder TC4001 (Is this any good> The rms on it is 400 rms. I believe the subwoofer's is much lower than this. So there shouldn't be no problem connecting this amp to my sub if I set the db/gain properly correct? Also the max watts this amp has is 1200 watts, so it won't blow my sub unless i don't crank it to the max right?...just want some feedback/answers to this. Thanks in advance.

Re: Should Amp RMS Match Sub RMS? (Civic_07)
Take the sub out of the box and google the model number. Get the RMS rating, DVC or not, and what ohm. Then buy an amp that is at least the same RMS but more is advisable.
The MTX TC4001 is an ok amp. It's 400watts RMS @ 2ohms and 200watts RMS @ 4ohms. That's why you need to know the subs specs before buying an amp. Or you can spend a lot more for a very powerful amp and have enough but still not know how the sub is hooked up.

Thank you for the information, So im guessing subs only come in 2 ohms or 4 ohms?
So say a sub like the MTX Thunder t4500 12 inches. it has 4 ohms. The rms is 225watts. So lets pair that up with the tc4001 amp. So that's 200 rms @ 4 ohms. So It would be enough to pound but I can't crank it that much right? What's better, the sub ipedence being 2 ohms or 4 ohms?

Re: (Civic_07)
2, 4, 8 ohm subs are normal, but there are a lot of variations.
If you want to save some money get a single voice coil(svc) sub that is 2 ohms or a dual voice coil(dvc) sub that has 2 - 4 ohm voice coils(so it can be wired parallel to 2 ohm load for the amp). The MTX tc4001 is 200watts RMS @ 4 ohms and 400watts RMS at 2 ohms. You see that it gives you more power without you having to buy a larger amp. Caution: It does make the amp work harder(hotter) and will have slightly higher distortion.
It's easier to choose a sub/amp setup when you have a specific budget. Because once you have the amp or the sub you must buy the other to match(amp should always have more power than the sub needs).

To bridge a two channel amp.. you run a wire from the amps Positive (+) output on channel one to the Positive (+) input terminal on your sub. Then you run a wire from the amps Negative (-) output on channel two to the Negative (-) input terminal on your sub.
