Rig an iPhone to old speakers?

I have no idea if this is possible or not, but I've tried and failed enough times that I figured it's time to ask. A pair of JVC speakers from about 1990 with positive and negative terminals on each + old Sony headphones stripped to reveal the wires + phone = music somehow?

Is there any way possible to get anything back? Should i go look for my phone?

Okay, so 2 days ago i left my cousins house and my iPhone dropped in the sewer! I didn't know what to do so i left it there cause it was pretty late at night. So as I'm gone, somewhere else… My cousins and I tried calling it… When we did it was still ringing. So when we got back at the sewer we thought we seen it but couldn't get it out. When we tried calling it again, my phone sadly went to straight to the voicemail. I know i should've went upon the situation totally different and tried to get my phone out As soon as possible. Now i have no phone, and i had SO many important things in that phone, sadly I NEVER backed it up… What should i do, I'm hurt as hell its literally like a death to me especially hearing it drop in there. I Know i should've backed it up and atlas use the 5 GB of space to do that even tho it was way more than 5 GB. What should i do guys? Btw can that phone be fixed if found or have any value?

My phone crashes when its locked?

I don't know if this matter but i droppymy iphone 5c at a low height yesterday, no cracks except there's a rattling sound inside like a loose screw. And recently after that incident everytime i would like my phone and wait 10seconds, it crashes. I press unlock and nothing happens. Home button, nothing happens. I reboot the phone and the same thing happens. So far what's working is putting on the never autolock setting.

IPhone charging when storm knocked out power?

So I was charging my iPhone when the lights flickered and the power went out, I didn't have it in a surge strip, I know I should have be will in the future. I unplugged my phone and checked it and all seemed to be fine and still is. My question is… Can a power outage hurt or fry my phone or would it have to be a surge to damage it? And if so would there be immediate signs of damage if phone was hurt during outage or power surge? Can the phone handle a power outage or surge when plugged in if only happened few times or is there always damage done even if minimal and unnoticeable at first?

My iPhone 6S can never find Wi-Fi?

For example, when I'm in my bedroom, my macbook will have full Wi-Fi bars, my girlfriend's iPhone 6S plus will have full Wi-Fi bars, but mine will have only one, and eventually disconnects altogether after a couple minutes. I've tried taking the case off and re-booting the phone - doesn't help. I've also tried making my phone "forget" all Wi-Fi networks, then reconnecting. And yes, my phone is connected to the same network as the other devices. Thank you!

Added (1). Also - my GPS locater has a very hard time finding where I'm if I'm not connected to Wi-Fi. I have AT&T, and so does my mom. When we're standing next to each other, her iPhone 5 knows exactly where we're, while mine hardly knows what town we're in (giant blue range circle).
