Best way to wire my dvc sub to amp??
|
| I have a few questions about wiring my Cerwin Vega HED sub. It's dvc (4 ohms per coil) 150W RMS and i have a pair of rear speakers (4 ohms 120W). i need advice on connecting all speakers and an appropiate amp 1) i think a dvc sub can be run maybe 3 different ways? connect both coils in series (8 ohm impedance) or both coils in parallel (2 ohm) or connect coils separately in stereo (4 ohm). is that correct? 2) is it ok to connect the sub (at either 2 or 8 oms) with different impedance speakers (rears at 4 ohm) to a multichannel amp? if i do, does that mean that lower impedance speaker will draw all of the signal? or most of it? or so much signal/current draw that the higher impedance speaker will produce almost no sound? 2) i was thinking that a 2 channel, tri-mode amp with built in crossovers (like a kicker zr210, jvc xa2125, lanzar vibe210,...) could give me the versatility i was hoping for? i could bridge the 2 channels for the sub and still use the individual channels to power the rear speakers. any thoughts to that? & would i still need as much filtration if the amp has built in crossovers?? 3) or maybe use a bridgeable, 4 channel amp for 3 channels: run rears on channels 1 & 2; bridge 3&4 and run sub on that. any thoughts? please help & thanks, kgj |

| i thought for my subs, the loads would be either 2 ohms in parallel or 8 ohms (series)? anyway, if understand correctly it is ok to present different impedances on different channels on an amp? i don't have money or space to afford getting 2 amps that's why i need one to do it all. thanks your your help. |

rebel_in_la | your sub is 2 ohm in parallel and 8 ohm series... no mater what Derek says... you can wire the speakers with different impedences to the same amp as long as your overall impedence does not drop below the capability of your amp. tri-mode will help the sound if you get the rite crossover...but it wont be the best you ever heard.... |
