2, 2ohm Dual Voice coil subs to mono amp

**txallen** · 07-25-2010, 12:08 AM

ok, Here it goes,
I have 2, 2ohm dual voice coil Kicker CVR 12" subs in a box that will be placed under my truck seat (down fire). The subs are 800 watt max, 400 watt rms. My head unit has a SUB jack that is mono. To my best knowledge, i need a mono block sub amp. I have wired the subs in parallel (as the kicker book said) and wired to the jacks that are mounted in the sub box. Ultimately i now have only ONE set of wires (one positive and one neg.) to run to the amp. All the mono amps i have looked at have TWO places to put two sets of wires. What am i missing?. Any help would be greatly appreciated

Thanks in advance

Hey and welcome to the website! This website is dedicated to the process and technologies involved with putting a computer in a car for music/gps/etc, and this sub forum for the issues integrating with a car audio system. While someone here may have an answer for you I would hate for you to wait around on a forum that isn't really for you. You would be better off asking that question on a car audio dedicated forum.

i may have an answer

most monoblock amps with multiple output terminals are really just have multiple parallel outputs-- so connecting 2 subs to the outputs on the amp is the same as what you did inside the box..

now you just need to make sure that the amp can support the load you have setup. because, if you paralleled both vc's, and then paralleled the subs, you are at about a 0.5ohm end load on the amp-- and that will be relatively hard to find a amp for.

imo, you should wire them for either a 2, or 4 ohm end load, so that the proper amp will not cook..

Well, i have wired the voice coils parallel and the subs in series(as the diagram shows on the Kicker website). which gives the end load 2ohm. but... the diagram also shows voice coils in series and the subs in parallel which still gives a 2ohm load. Is either way any better or just personal preference?

not really. just different options-- that is the entire reasoning for dvc subs-- more wiring flexibility.

Thank you soundman. you have helped me more than you know. now i have a stupid question. i have one set of wires coming from the sub box now because i have wired the subs together. That one set of wires hooks to the amp, but the amp has 4 screws: left + right+ and left- right-. which set of screws do i hokk the one set of wires to? and the amp only has one channel mono. i am actually losing sleep over this..haha

are you sure it is a mono amp? what is the model #?

because the blocks are usually tied together, you should be able to just connect it to the same parts-- ie: either left +/-, or right +/-..

These diagrams should help you figure out how to wire your box to the amp correctly.....

This is a two channel amp. You need to wire your subs like this with that amp......

If you wanted to be pushing 2ohms, you should have gotten 4ohms DVC's instead and wired like this...

What you need for you current configuration is a mono amp wired like this....

Hope this solves your problem!!!
