Bridging.

[Plex]

Hi I'm fairly new to this car audio upgrading as you might be able to tell from my next question.

When bridging an amp dose it always become mono output. I was looking at the pioneer GM A404. And that has 2 different configurations for bridging 1 for mono and 1 for stereo. Most seem to have just 1 bridging option so dose that mean it's just mono. I always assumed that 2 speakers made a stero sound. So if I bridge a 4 channel amp, ie channel 1 and 3 with 1 speaker and channel 2and 4 with another speaker dose that equate to stereo sound.

Sorry for long drawn out question.

I should say aswell that it's for 2 door speakers not subs.

When I try googling that model of amp nothing comes up... But most amps you bridge channels 1-2 and then 3-4..... Not 1-3 2-4

GM A4604. Sorry. Yeah I understand bridging it's just getting stereo sound rather than mono. The amp I mentioned has to different configurations for bridging 1 for mono and1 for stereo

I realise that last post makes me sound like a ****. I clearly don't understand bridging otherwise I would not be asking the question.

Yes you can bridge a 4 channel and retain stereo

Just make sure you have the left rca inputs going to the left bridged channels and the right going to the right. It's pretty easy

You just need to maintain an individual left and right channel.

Each pair of channels would technically be bridged/mono, but if you have a bridged/mono left and a bridged/mono right, that's still stereo.
