ok I think I have the whole ohms thing down BUT if you have 2 Dual 4ohm subs and a 2 channel amp does each channel see 4ohms or do you still wire them together to get 1ohm a piece, also what does bridged mean, all these questions come up from me thinking about getting a ZED duece amp and it says Continuous Output Power into 2 ohm per channel 400rms, and I plan on getting 2 D4 sound splinter rl-i's and was wondering it this amp wold be good for those subs
