Help with Sub Connection??????

[Mcintoshman 10+ year member]

What about running a set of subs 2 ohm stereo versus mono? Soundstream Tech said there is no difference but that does to make since.

I figured out all the wiring of the subs just not sure about the stereo versus mono on subs.

The wiring of the voice coil would have nothing to do with the amp seeing a mono or stereo. Right?

Bridging a pair of channels is what tells the amp that it is a mono load versus running a sub weather it be 2 ohm or 4 ohm wired to say channel one and the other to channel two making it see stereo.

My issue is with these Soundstream Van Gogh VGA-600.2 amps that I got to go in the wifes car. They only allow for 2-4 ohm stereo to two channels or 4 ohm mono bridged to one channel. I had already purchased a pair of dual 2ohm Alpine type-s's and they do not seem like they can be wired to work and get full power from the amp. Would I be better to run them 2Ohm Stereo or 4Ohm Mono and what is the difference?

4Ohm Stereo/2Ohm Stereo/4Ohm Mono

VGA600.2 / 150w X 2ch / 300w X 2ch / 600w X 1ch

I Hope I broke this down better I just want to fully understand because I thought I knew how it worked untill I talked to a Soundstream tech and he said by wiring the two subs(Dual 2ohmVC) up it would make them show 2ohm MONO and I had thought MONO had to do with how they are connected to the amp not the wiring of the Voice Coil.

you cant run a pair of dual 2 subs at 2 ohm stereo OR 4 ohm bridged

IT would be 2 ohm bridged or 1 ohm stereo/4 ohm stereo

If you could make it see the 2ohm as you stated and connected to ch1 and the other sub to ch2 would this not be showing the sub stereo? to show a mono would you not have to bridge the two channels on the amp?

I see how you can make a single dual 2ohm show 4ohm and 1ohm but how do you make it show 2ohm without running a second one at 4ohm then even if it was connected like this to ch1 or ch 2 would it not see stereo with out it being connected to the pair of ch bridged?

How could you make a pair of dual 2ohm show a 4ohm stereo? I would think it would be showing 2ohm/1ohm and connecting to amp would say weather or not it was stereo or bridging making mono.

Thanks for the help because I think I am figuring it out then I get lost again.
