Bronze Member Username: Subzer0Richmond, KY USA Post Number: 99 Registered: May-05 | will someone go over the whole spill of what exactly 1000x1 100 x 2 150x 4 yada yada is on an amp and what 1/2/3/4 whatever stable the amp is also means? also for the subs: what is the ohm meaning on them? i have rockfords that are 4 ohm.. I dunno wtf this has to do with anything.. I hope someone can understand what i'm trying to ask.. like what is a mono 1 channel.. and 2 channel and what does it have to do with a sub, also, does the voice coils have anything of relevance with any of this? |

"then you could run each sub to its own channel and run it at 4 ohms.... " and if u have a 2 channel amp and u run a 4 ohm sub(svc) to each channell isnt that going to be 2 ohms? |

Silver Member Username: Tdeaton1021Near Tampa, Florida USA Post Number: 436 Registered: Sep-04 | well u say u have rockfords...plural... so im assuming 2... so if both are 4ohm... then wire them to 2 ohms... so you want a 2 ohm amp that will push the right amount of power (RMS) at 2 ohms |
