I have multiple questions about car audio amps and subs?

[JR]

I have two kicker CRV 12s DVC and they are 400rms each, with 4 ohms per voice coil. I want to buy a Hifonics HFi1000D and it says at 1 ohm i would get 1000 rms per channel...there is two positive and two negative terminals on this amp so how would i get 1 ohm with my two 4 ohm speakers.. if possible, is it bad to run two four ohm speakers at a final impedance of 1? Finally if i have 4 ohms per voice coil that means that i have 8 ohms for each speaker, so how would this all pan out? If you have any other tips to help me out please feel free to tell me because i'm new to car audio.

That amp is a monoblock which means it's only one channel and it is rated at 1000 watts RMS into a 1 ohm load. It has two sets of output terminals for convenience. All you have to do is parallel(+ to + and - to -) the voicecoils on one sub and then hook up to one set of terminals on the amp. Then just do the same with the other sub. This parallels all 4 voicecoils together which incidentally results in a 1 ohm load that the amp will "see". Since you have 4 seperate voicecoils each will "see" 250 watts RMS. Or you can look at it as each subwoofer getting a total of 500 watts RMS. Keep in mind that it's always better to have more that enough power than not enough. You can always turn the amp's gain/s down if you have more power than your subs can handle but if you don't have enough power you will distort the signal and possibly damage the subs. Good luck.
