I am looking for a 4 channel amp that puts out 75 watts per channel. I would also like to it to be bridgeable. Looking to spend $100.

looking in the amplifier classifieds section or put this into the WTB section, you can get more offers that way

Browse the classifieds... You need 75w at 4 ohm? I can get you close 75w x4 at 2ohm for under $100 shipped

I run a us acoustics 4050 on my front stage, I am considering putting it up for sale just to buy a matching for channel to my new sub amp.

I love the us acoustics it does 50x4 @4 and is bridgeable.

I would say bump your budget to $150, and then there will be many choices. For example, PPI's "Sedona" or "Black Ice" line of amplifiers (Black Ice is supposed to be better). I can't think of solid _new_ amp that costs $100, and you need something solid, preferably with biggish heat sink since you want to bridge channels.(For example). To tell the truth, in FL or TX summer heat, I probably would be fully comfortable bridging amp channels for subwoofer only on a good Class D amplifier, like PPI P900.4. Bridging channels puts more strain on amplifier as the bridged channels are seeing internal 2ohm when 4ohm speaker is connected. Class A/B amps are notoriously inefficient running at 2ohm.

For something close you $100, look at MB Quart ONX4.80. It should be ok amplifier for full range speakers, but I am not sure if I'd want to bridge it for subwoofer. I have a similar older MB Quart that gets stupid hot during summer months simply powering active front stage (a pair of woofers and pair of tweeters, all 4ohm).

Ok say I bump my budget to 150. Can I get a 4 channel amp that would allow me to bridge 2 channels safely? What about 60x4?
