Default Bridging ?

I'm bridging a SoundStream PN4.520D to one pair of BT 7.1's with a Sony HU NO other speakers in the bike. I think I have it bridged correctly and this being the first time I've ever bridged anything. My question is when you bridge one pair of speakers off a 4 channel amp like in my case do you lose "balance" right and left? because for some reason when I turn the balance all the way to right or to the left I'm still getting sound out of the other speaker? Did I not do something correctly? Any suggestions would be greatly appreciated.

Thanks

Fader is your new balance between the two. You can't balance left or right like normal because your using front channel inputs on one speaker and rear channel inputs on the other.

Right on Bates! Thanks brother for the clarification!.................Another ? when tuning with the DMM according to Slyes chart with this set up were speaking of should my target number be 250W/31.6V as the SS is technically putting 260 watts to each channel now or should I step down and tune it to 200W/28.3V?

Thanks

I'll defer on that one because I do not Tune via DMM. I'm strictly a tune by ear guy. Even tuning by ear I don't tune it right to the edge. I always leave myself a little wiggle room to keep from seeing that magic smoke.

I'd say that 520.D is doing a little less than rated bridged. Realistically you're looking at about 220 watts max. And that would be at 14.4 volts. You're not gonna maintain 14.4 volts unless you're at highway speed all the time. In town you're gonna be at 12-13V. Error to the side of caution. I'd stay around 25-26 and listen with your ears. Those 7.1's should sound pretty good with 200 watts going to em!! If you don't like the way it sounds. Unbridge em and run em at 90 watts. That's what the 520.D benched at. 90 x 4 @ 4 ohms.

Honestly Gan, I've tuned it to the 150W/24.5 the 200W/28.3 and the 250W/31.6 and they all sound really good I think Im just gonna leave it in the middle at the 200W/28.3 and let my buddy roll with it! The only other concern I have is if the volume is at 0 you hear nothing which should be the case! as soon as I turn the volume to 1 I hear like a slight buzz sound more so on the 3&4 channel the left speaker then the 1&2 channel right speaker is this normal? And last not to sound stupid but when bridging like in this case does it matter which set of bridged +/- speaker wires go to which speaker?

Not to get off subject to far with bridging.

Does the amp go to a 2 ohm load when bridging the two channels with a 4 ohm speaker since you are basically joining 2 channels?

Or is it still a 4 ohm load?

So the question is do you set it for a 2 ohm load or a 4 ohm total load when bridging?

I don't want to confuse others just trying to keep them from letting the magic smoke out of their equipment.

Great point!!!! Can u even run a 2 ohm speak in bridged mode since all specs seem to only reference the 4 ohm figures? Will the amp become the magic smoker?

The speakers are bridged @ 4 ohms fella's. Amp becomes two channels.
