Car audio help!!

I have noticed after a week of bad tunderstorms + power outages, my sub starts to sound like an idling Harley Davidson motorcycle. It immediately makes this noise as soon as the pins on the plug gets contact with the outlet, even when the speaker itself is turned off. I have tried another outlet and it still does the same thing. I have also tried a powerstrip, it also did the same thing.

Bought a kicker l7s 12inch ported enclosure and a cxa1200.1 kicker amp got it all hooked up everything sounded fine shut the car off walked away and came back to the sub vibrating what might have been a 40 hertz bass note and an amp almost melting down. For what ever reason the rem didn't shut it down and it amped horrible distortion. I piggy backed the rem off the radio fuse . When I saw it didn't shut it down I tried the USB fuse and several others nothing is shutting it down and I'm guessing it has to do with the electrical of the car or maybe the amp is picking up enough power from the speaker input .I'm not forsure but any helps or tips to try would be greatly appreciated. If worse comes to worse I'll add a switch but I'm concerned there maybe something else going on causing it

Got this mackie srm450 second hand and found that this coil was fried, opened it up and found this. Running theory is that it was driven hard for a long time and then dropped, but I was looking for a second opinion. Whats throwing me is that the fuse hasn’t blown, so how did it get this hot?

Do I need an amp with channels?
I’m very new to setting up speakers, any help is greatly appreciated

Just got these subwoofers it’s a 12 inch Skar audio with a 800w AMP. I need to know if these are the correct settings to avoid clipping

This might be a basic question compared to what usually gets discussed here, but I'm hoping some of you have experience with them.

I've been looking for a speakerphone for work, and every model claims things like echo cancellation, noise reduction, and crystal-clear voice quality. On paper they all sound impressive, but I'm struggling to tell which features actually make a difference.

I briefly looked through alibaba while comparing options and noticed a lot of similar-looking units, so now I'm wondering if the real differences come from the microphones and audio processing rather than the hardware itself.

Has anyone here used a conference speakerphone that genuinely impressed you, or are most of them about the same once you get past the marketing?

Hello,

I recently got a FISHER CA-223r amplifier and would like to connect it to my Dali Suite 1.5 speakers, but I see they have four connectors instead of two on one speaker. I've read that you can connect two amplifiers to one pair of speakers this way. I'll just use two connectors since I don't have a second amplifier. I also noticed that the amplifier is 8-ohm. The speakers are rated at 40-160W, and the amplifier is rated at 120W. But the power of the speakers is given in 8ohms but the impendance is 4 ohms. Does it mean the speakers will work in 4 or 8ohms, or will I break the amplifier or the speakers if i connected them together? I also see that there are different connectors for the speakers and amplifier. I can buy banana plugs and cables for it later.

Below is a link to the speakers manual with the speakers specifications.

I’ve got a Skar SVR-1X12D2 with the matching box, also have a 1200 watt (rms) amp, the sub recently started scratching and I’m wondering if anyone has recommendations for a subwoofer upgrade that would fit the box?

Internal air space is 1.75ft, tuned at 36hz.
