  • Retro TV

    Hey everyone. We are going to make a modern smart TV and build it into a retro style cabinet and was wondering how to do the audio side. Was planning on a 2.1 amp and built the speaker into the cabinet but he would I get the audio to function with the tv sound and remote?

    Just be sure the TV has an audio output that will work with the amp input. The TV remote will control the volume of the audio out. Most TVs will allow you to turn off the internal speakers as well. But IMO not going at least 5.1 is a mistake.

      The sound bar amp my be a solution due to it having ARC built in

          I think you could but it's one more thing to have to power inside your cabinet. Why not use an amp that's already 2.1?

          Lepai LP210PA 2x30W + 60W 2.1 Channel Mini Plate Amplifier TPA3118 with Power SupplyLepai's LP210PA compact 2.1 plate amplifier makes it easy to create your own powered subwoofer/satellite speaker systems. At only 4.5" wide and 5" tall, you can install this amplifier in even the smallest subwoofer designs; however with 60 watts to the subwoofer and 30 watts to each satellite you can expect powerful output capability. This is the perfect plate amplifier for use in office, bedroom, or even portable subwoofer/satellite speaker systems. The straightforward features make the LP210PA extremely easy to connect and setup. Input is handled through stereo RCA connectors. For the power outputs, there is a Phoenix connector on the back of the amplifier to connect directly to your subwoofer driver, along with binding posts on the front of the plate for simple connection to a pair of separate satellite speakers. The adjustable subwoofer volume, crossover frequency, and main speaker volume makes it easy to create a smooth transition between the subwoofer and satellite speakers. In addition, this amplifier includes a unique channel selection switch, which allow you to turn off the satellite speakers and run just the subwoofer by itself allowing you to run separate powered satellites from the stereo RCA pass through outputs.This package includes a 15 VDC 4 amp switching AC adapter to deliver noise free power to the LP210PA. Use this adapter with confidence, because it meets all UL safety requirements and has built-in overload protection. When in standby mode, this adapter meets level VI energy saving efficiency requirements.Amplifier Specifications: • Output power: 2 x 30 watts + 1 x 60 watts RMS • Minimum impedance: 4 ohms • Amplifier chip: 2 x TPA3118 • Frequency response: 20 to 20,000 Hz; Subwoofer output: 20 to 150 Hz • Subwoofer crossover: adjustable 30-150 Hz 12 dB/octave • Satellite crossover: fixed 100 Hz 6 dB/octave • Input sensitivity: 245 mV • Input: RCA (with pass through outputs) • Outputs: Phoenix connector (subwoofer), binding posts (left and right outputs) • Power requirement: 15-22 VDC • Plate amplifier dimensions: 4.5" W x 5" H x 1" D (hole size: 3.75" W x 4.125" H).Power supply specifications: • Output voltage: 15 VDC @ 4A • Input voltage: 100-240 VAC @ 50/60 Hz • DC output cord length: 4 ft. with 2.1 mm x 5.5 mm x 10 mm with center positive plug • AC input cord length: 4 ft. • Dimensions: 4.6" L x 2.14" W x 1.33" H.
