Stupid question for the day- in common person's terms, how to I bridge 4 speakers from a 4 channel amp? Maybe I need to take a step back but I'm definitely scratching my head on this one. lol
You should glance over the sticky Audio System FAQs when you get a chance.
but here is the def from that sticky.
"Bridging An Amplifier – When you bridge an amp you are wiring it in such a way that you combine two channels into one. Essentially doubling the amount of power (watts) it produces. This is most often done when powering a single speaker like a subwoofer. There are a couple of things to pay attention to when bridging an amp. The first is whether the amp is designed to safely produce and handle the additional power from being bridged. If it is or not can be found in the spec sheet and those that are will often be marketed as bridgeable. Unlike the above wiring options, when bridging an amp you’re not looking to make sure your amp has enough power to drive your speakers but that it won’t produce so much power that you blow the speaker. Remember, in this configuration you’re DOUBLING the power being sent to the speaker. Again, this is done by combining two channels. Picture outputs of a 2 channel amp, almost always they will be next to each other. You have a left and a right channel and each one has its own positive and negative. It’ll be configured as some combination of + - - + or maybe + - + -. As can be seen below the positive side of one channel is connected to the positive terminal of the speaker and the negative terminal of that speaker is connected to the negative post of the other channel. Also shown in the picture is how this causes the impedance of the speaker to be cut in half as far as the amplifier is concerned."
I’ve been looking at that on their site. Page 10 references the amp I’m using but doesn’t show me bridged. I’m obviously an idiot and am laughing about this lol
ok take the ceramic resistor and solder it in line with the positive side! See pic!!
Then take both positive (Horn and woofer) and connect them to the "Bridged positive" of the amp.
Take both negative (Horn and woofer) and attach to the "Bridged negative" of the amp.
Repeat the above steps for the other side and connect them to the other "bridged" channel
Just following along... Out of curiosity does it matter where in the signal the 4 ohm resister is soldered in? Meaning if it's wired in after (from the amps perspective) the two wires join won't the amp see less than 4 ohm load? Hope this question makes sense?
