Bridging 4 channel amp into 2 channels for 8 ohm mids

Recommended Posts

I have a 4 channel amp that puts out 300w rms x 2 bridge mode into 4 ohms but I have 4 x 8 ohm mids rated at 150w rms each. So I would like to know a few things that I am unsure about :

1. If I run the amp bridged (2 channel mode, 300w rms x2), can I use ch 1 & 2 as a left input and ch 3 & 4 as a right input so I still have stereo sound? Will I loose stereo seperation this way?

2. Since the mids are 8 ohms, if I run them in parallel for each side (4 ohms total load) does this mean that each mid will get about 75w rms?

You won't lose any stereo separation because you are using the left and right rca's. If you run the two mids in parallel on each side at 4 Ohms the amplifier will produce 300 watts as you mentioned so each pair will see 300 watts/ 150 watts a piece. :) I would go easy on the gains, and have your x-over set properly.
