Parallel or Series?

[CSVT1214]

I have an Alpine V12 MRV-F357 amp, and I just picked up a new 07 Kicker Comp VR (4 ohm DVC).

I know very little about car audio, so I need some help with the sub wiring. Should my sub be wired in parallel or series?

Here is the specs on my amp:

Wire the voice coils in parallel. Two 4 Ohm coils in series will give you 8 ohms, so in parallel they will give you 2 ohms, which the amp looks like it can handle.

I have a question to add to this

Say you have a DVC sub, and a 4 channel amp. You want to bridge the 4 channel amp to 2 channels. The problem is the sub has one connection and uses jumpers to achieve series and parallel.

I don't think you would want to run the 2 bridged channels in to the same connection or doesn't it matter

Did the sub not come with a wiring diagram?

yes it does but there is only one input on the sub, Then you use a jumper to achieve parallel or series.

Similar to this

I take it I just wire to the prongs that you connect the jumper to

From Alpine's website:

Are the MRV Series amplifiers 2 ohm stable?
08/21/02-Most of the MRV Series amplifiers are not 2 ohm stable unless it is specifically designed to be used as a mono amplfier.​

I also downloaded the owners manual from Alpine for your amp and while it says channels 1-4 are 2 ohm stable (they'd have to be since you can bridge 1-2 and 3-4), Channel 5 only references 4 ohm capability.

This means you should not wire the dual 4 ohm voice coils in parallel to the MRV multichannel amp you have.

So in this case your options are:

1 Wire it in series, presenting an 8 ohm load on the mono channel
2 Return the sub and exchange for a sub with a single 4 ohm voice coil
3 Return the sub and exchange for a sub with dual 2 ohm voice coils wired in series (for a 4 ohm load)
4 Return the sub and exchange for a sub with dual 8 ohm voice coils wired in parallel (for a 4 ohm load)

Let me know if you have any additional questions.

Damn, I had a feeling that's what you were going to say.

Well in that case, my C-VR is now for sale. Anyone interested, send me a PM.
