Someone told me that for mono amps, you run it at 4ohms if you are powering 1 sub and 2 ohms if you are powering 2 subs, is this correct ? Would I have to see that the sub is 2ohm compatable ? -Right now I am powering two Alpine 12' type E's that are supposed to be 250w rms (600w max) with an Alpine v12 605 amp and the specs I found on Bestbuy.com say: 400W RMS x 1 @ 2 ohms, 12V, and 250W RMS x 1 @ 4 ohms, 12V. While in my manual, it just says 400 x 1 @ 4 ohms, 600w X 1 @ 2ohms (this is probably at 14v). How would I know which specs are accurate and what I'm running it at? Also, would I be putting the wrong amount of power to my subs? - Sorry if i worded everything a bit confusing, I'm new with this and would appreciate helpful feedback. Alright thanks allot. |

xdrummer03 Unregistered guest | The tags wrong then on the MRD-605. It does 600rms@2ohm.2ohms which 2 Type E Alpines will be at(if there 4omh subs). Yeh you have wrong amount to subs.The biggest you need is the V-Power MRP-M350. |

Anonymous | what excatly does OHM mean? how does it work when saying, for example, a 8 OHM sub working off a 4 OHM amp? |
