Curious. Anyone got experience installing a center channel?

[QUOTE="trumpet, post: 8391173, member: 628688"] MS-8 creates a single channel center signal. You can use the built-in amplifier to power it or use a free channel on a full range amplifier. How do you decide on an amplifier if you want more power? This may not be the best way to do it, but if you have 2 channels free, you don't have to bridge them to create a mono channel. A reason to not do this is if it's far more power than your center speaker can handle, such as 250W RMS bridged for a 30W RMS coaxial speaker. For example, I was using 5 channels of a Clarion XC6610, which is rated at 85W x 6 at 4 ohms. 2 channels bridge to 250W RMS, and I didn't want that much power going to my 2-way 4" components that composed my center channel. For those of you who know what you're doing in regards to headroom, disregard this paragraph. You guys probably know I have a lot of experience with CDT speakers.
