4 channel amp question
i want to bridge my 4 ch amp to run my fronts and im wondering if i need 2 sets of rca's or just 1 set since its being bridged
|
you only need one. the amp should have designated inputs for RCA's when running bridged. it is generally marked on the amp.
|
more info needed on your amp.... brand ...model.. ????
|
its an eclipse ea4000.

Interesting; even their web site doesn't include online manuals for their amps, only cd/nav units.
Do you have a 2 channel RCA you could quickly run across your seats from the front RCA premp outputs of your HU to the amp, and see if that is sufficent? What about throwing a pair of splitters on the inputs at the amp, using a 2ch RCA from the front? |

From what I have seen in the manual, when the bridge the amp they use all four input.
Now you can test it by using the pre amp out and back into the input for the other channel, set both swtich to stereo because you need to stereo bridge the amplifier, alternatively you can also use a rca splitter. There is also another way to stereo bridge, but you will have to use 2 sets of rca from the hu. The manual dosent say much on bridging. |
I maintain the only way to find out is try using only one set of preamp inputs.
My guess is you will require both F&R but its worth a shot. |
It never hurts to run all 4 inputs. Amps that only need two usually have an input switch but you have to be careful as one that only has a 2ch/4ch switch will share left with 1 and 3 and right with 2 and 4.
Get two Y-cords and plug both lefts into channels 1/2 and both rights into channel 3/4 to make sure you get mono left and mono right. |
so dukk, is your way for using two rca cords or one
