Projector, Sound System, or RCA Cable: Which TV Video Home Theater Upgrade Comes First?

From a used DLP projector to a Bluetooth surround sound system and two 1m RCA cables, this quick guide matches the TV video home theater upgrade to your display, audio, and connection needs.

Last updated Aug 17, 2026

Quick take

Upgrading a TV video home theater setup means deciding which missing piece to fill first: the display, the sound, or the cables between them. The 2500 ANSI DLP Projector for Home Theater Movie Lovers Cinema TV Video Full HD 3D covers the display side with 2,500 lumens, native 1024x768, DLP technology, 3D capability, and HDMI/network/RCA connections in used condition. The 200W Surround Sound Stereo System for TV 5.1/2.1 Ch Home Theater Subwoofer handles the audio side with Bluetooth, HDMI audio input, a 4-inch subwoofer, and a multi-channel speaker layout. The remaining two products are 1m composite RCA cables for connecting devices with legacy AV jacks.

Product notes

2500 ANSI DLP Projector for Home Theater Movie Lovers Cinema TV Video Full HD 3D

2500 ANSI DLP Projector for Home Theater Movie Lovers Cinema TV Video Full HD 3D

This is the only display device in the roundup. It is listed as used and comes with DLP projection, 2,500 lumens, native 1024x768 resolution, 3D capability, and a connectivity set that includes HDMI, VGA, S-Video, composite RCA, network, and RS232. The feature list also includes built-in speakers. The reason to choose it is the projected picture and the wide input selection. The limitation is the used condition and the fact that the projector price sits above the two cables in the table.

200W Surround Sound Stereo System for TV 5.1/2.1 Ch Home Theater Subwoofer

200W Surround Sound Stereo System for TV 5.1/2.1 Ch Home Theater Subwoofer

This is the only audio-only product in the set. The title says 5.1/2.1 channel support, and the description includes a 4-inch subwoofer, a built-in receiver, and a central, front, rear, and main speaker/subwoofer layout. Bluetooth connectivity and HDMI audio input are both listed, so it can work with wireless sources and a TV that has HDMI. Choose it when you want a multi-channel surround field instead of relying only on the TV's built-in speakers. The trade-off is that it is the highest-priced item here and includes more speakers to arrange than any other product.

3 RCA Male to Male Composite AV Cable 1m for TV DVD Home Theater Audio Video

3 RCA Male to Male Composite AV Cable 1m for TV DVD Home Theater Audio Video

This is the more basic of the two cables in the table. It is a new, black, 1m cable with three male RCA connectors for composite video and stereo audio. The listing describes it as a suitable link for TVs, DVD players, home theater systems, and other compatible AV devices. The reason to choose it is its position as the lowest-priced item in the roundup. The limitation is that the listing does not mention shielding, gold contacts, or the flexible PVC details that the other RCA cable calls out.

3 RCA to 3 RCA Male to Male Composite AV Cable for TV DVD Home Theater- 1m

3 RCA to 3 RCA Male to Male Composite AV Cable for TV DVD Home Theater- 1m

This second cable shares the same general job as the other RCA option. It is new, black, and 1m long, with three male RCA connectors on each end. The listing highlights gold contacts, EMI/RFI shielding, an ultra flexible PVC jacket, and color-coded connectors. The reason to choose it is those listed build details. The limitation is that its listed price sits slightly above the other cable's price, so the decision comes down to whether the extra description is worth the small difference.

Final recommendation by use case

  • Projected picture: Choose the 2500 ANSI DLP Projector for Home Theater Movie Lovers Cinema TV Video Full HD 3D if you want a used DLP projector with 2,500 lumens, 3D support, and multiple input options.
  • Surround sound: Choose the 200W Surround Sound Stereo System for TV 5.1/2.1 Ch Home Theater Subwoofer if Bluetooth multi-channel audio and a subwoofer matter more than keeping the spend near the cable prices.
  • Simple RCA hookup: Choose the 3 RCA Male to Male Composite AV Cable 1m for the lower listed price, or the 3 RCA to 3 RCA Male to Male Composite AV Cable for the listed shielding, gold contacts, and flexible PVC details.
