Hello, Could you recommend an IC amp for small multimedia speakers with following spects:

External Power Supply
Must fit inside the speaker cabinet of 4.5 x 6.5 x 11.5 in Internal Dim.
Mono for each Speaker
Low Dist <0.5 @ full power
Min 12W clean RMS power
and of course good sound.

Thank you for your input

Depend on how adventurous you are.

TPA3118D2DAP class D... http://www.ti.com/lit/ds/symlink/tpa3118d2.pdf

Or any of the chip amps mentioned on this forum.

Amplifier kits or modules from Madisound or Parts Express.

You are in the GTA...try Sayal if there is one close to you...they have amplifier kits in some of their stores.

The LM1875 has tons of support and will provide >12W with a supply of 18V or more, into 8Ω.

There are hundreds that can be used.
Download the data sheets of the National chipamps for starters.
Read the Threads discussing build recommendations.

TDA2050 with dual rail DC supply based on the Radio Shack CT 25.2V 2A transformer will output 14 watts pre clipping into 4 Ohms or 10w into 8, both channels driven continuous sine wave. LM1875, TDA2040 or TDA2030A will also work, but with slightly less output.
Buy your ICs from a place like DigiKey. Forget eBay. All I tried were fakes.
