Stereo and Home Theater Systems questions, answered by experts

DIY is possible for basic setups. Professional installation ensures optimal sound, visuals, and wiring.

The length of coax cable can affect the signal. Coax cables and their connectors all have a small amount of electrical resistance, which means that the longer the cable and more connectors in the system, the weaker the signal strength. In most homes, the signal loss is tiny, but systems with coax cable lengths over 100 feet will likely experience signal troubles.

Installation typically takes 1-2 days, depending on wiring and equipment setup.

Identifying the source of noises is your first step to soundproofing a room without overspending. Generally, sound comes from inside or outside of the house. Inside noises include creaking floors, living noises like TVs in the living room, cooking sounds, or kids being kids. External noises generally include incremental weather, disturbing neighbors, and street traffic. Inside noises require you to soundproof floors, ceilings, and doors, whereas outside noises may require you to soundproof your attic, windows, and walls facing the streets.

Costs depend on speaker type, labor, home layout, and whether custom wiring or mounts are required.
