In a quite place part 2 after the deaf girl cuts the wire off the speaker how does it get power

1. What the film actually shows: the cut cord and the audible payoff

The sequence in question is captured in plot summaries: Regan uses a clipper to cut a cord off the amplifier after using amplified feedback to wound the creatures — the physical act of severing the cord is plainly shown in the sequel’s plot description ^[1]. The narrative emphasizes the dramatic and tactical use of electronic amplification as a weapon and a risk in a world where sound equals death, but it does not linger to annotate the power chain feeding that device on screen ^[1].

2. What the filmmakers have given viewers as visual context about power sources

Outside the explicit moment, the original film and franchise imagery include visual cues about off-grid electricity: viewers can spot rows of solar panels during exterior shots of the Abbott home, which has been widely noted in public FAQs and fan observations as indicating solar power is at least part of the family’s infrastructure ^[2]. Movie-discussion threads and technical fans have seized on these shots to argue that the Abbott family relies on localized, quiet electricity generation rather than loud fossil-fuel generators that would draw the monsters ^{[2] [3]}.

3. How sound designers' commentary intersects with the question

Interviews and coverage of the franchise’s sound team underscore how central amplified noise is to plot decisions but do not delve into power logistics; sound editors describe creative rules about when loud noises can be masked or used strategically, and how speaker placement and mixing produce the devastating feedback effect, but they do not claim the film provides a technical blueprint for powering devices after the cord is cut ^{[4] [5] [6]}. Those sources explain the why of amplification in story terms without addressing the electrical how.

4. Fan answers and plausible technical explanations — and their limits

Online Q&A and fan forums canvass plausible explanations: survivors in a post‑apocalyptic rural setting could use solar panels with battery storage and an inverter to run an amplifier, or a standalone battery‑powered portable amp could be in play; wind or hydro turbines are sometimes suggested as quieter community-scale options too, and technical threads on Movies Stack Exchange have proposed hydro/wind/solar as sensible low-noise generation sources ^[3]. These are rational engineering guesses grounded in shots of solar panels and inferences about survivors minimizing audible infrastructure, but they are not authoritatively confirmed by the film or its creators ^{[2] [3]}.

5. What the official material and interviews do not answer

Neither plot summaries nor the documented interviews with filmmakers and sound editors provide a definitive on-screen explanation of how the amplifier remains powered after Regan severs the cord; the production-focused pieces center on sound design, not electrical continuity, and FAQ/forum notes point to solar panels without stating that specific devices were tied into them during that scene ^{[1] [4] [2]}. Where the movie is silent on details, fans have filled the gap, but the absence of a canonical answer should be acknowledged: the film prioritizes tension, not technical exposition ^{[4] [6]}.

6. Bottom line — the most defensible conclusion given available reporting

The most grounded conclusion supported by cited material is that the film does not explicitly say how the amp stays powered after the cord is cut ^[1], while the strongest in‑world hint — visible solar panels around the Abbott home — makes a battery-backed solar system the most plausible diegetic explanation, supplemented by common-sense fan theories about portable battery amps or inverters; however, none of these technical specifics are confirmed in the sources reviewed ^{[2] [3]}. The filmmakers and sound team discuss the mechanics and consequences of amplified noise extensively, but they stop short of answering this precise electrical question ^{[4] [6]}.
