Bridging front and rear sides (vertical staging)?

[abqrb2000 10+ year member]

have a 4 channel amp for my front stage. I do not care about rear fill so much. I understand the active concept. I also know I can bridge the 4 ch into 2 to get more power to my front comps.

My question is, when bridging, do I split the front signal or do I run the front and rear left together and the front and rear right together. The bridged signal would still have stereo? I thought this may be called vertical staging?

When bridging you would just want to split the front signal. Avoids the potential for having differing signals input into the amp.

If you biamping, however, you can utilize both the front and rear outputs from the headunit and use the fader as a form of level adjustment between the mids and tweeters. If you don't need this capability then it's easier/cheaper to just split the front output from the headunit as it saves needing to have four RCA runs from the headunit and instead allows you to only use two.

If you run active it depends on if you are using an external xover. If you aren't and are doing the active processing inside the headunit then you would need to use both the "high" (front) and "mid" (rear) outputs on the headunit.

In no situation would you need or want to combine both the front and rear outputs from the headunit to a single input on the amplifier.

The bridged signal would still have stereo?

Yes, as long as you only input the "left" signal to channels 1&2 and the right signal to channels 3&4.

Never heard that term in regards to amplifier wiring that I can recall.

There's "vertical" and "horizontal" biamping....but I don't think that's what you're referring to.

Great advice !!!!
