Video Transcript for Review of Furrion RV Speakers - Subwoofer - FSW8P12CF

Today, we're going to take a quick look at the Furrion Indoor Enclosed Amplified Subwoofer.Now, a lot of people are living more and more of their life in their RV, so they want to make them more comfortable and homey. This is going to be a great way to boost your DV player, your sound system by having a better bass sound in that sound system. This is going to project your bass sound from your TV or stereo inside your RV or camper and gives you that better overall sound quality.It's going to have a nice enclosed design to amplify that low-frequency output and the sound quality itself. We'll have some adjustment here for the crossover and the distortion, so be able to adjust those with those two knobs at the bottom. It's also going to have high and low level inputs. The high level input accepts a speaker level audio signal, and the low level input accepts a line level audio signal.

Have our attachments here on the side. It's going to have smart technologies to ensure that our stereo works whenever we want it to. Has a Climatesmart to keep our subwoofer running even whenever we're in the heat or the cold, and the Vibrationsmart helps to resist any interference from vibration when we're out on the road.It does come with some hardware to attach this in place. There's not a lot of instruction on how to get that hardware attached to the subwoofer itself. It comes with some instructions, but they're pretty basic as far as how to wire everything, and they don't mention the mounting hardware at all.

So, I would assume that you would take these little L brackets and attach them using the hardware included to the housing itself, but as far as I can see, there's no markings or holes predrilled in the housing to allow you to attach that. So you kind of are guessing as far as where you would attach this. Not an ideal system, in my mind.You could just mount this as is and then use the brackets to kind of bolster against it. So, you'd have two on one side, two on the other, or maybe kind of stagger them around on all four corners and just attach them with the two holes into a sturdy surface like a wood panel or a wall so that it's more or less installed in this direction. Again, it's up to you.

If you had this maybe under a seat on the floor somewhere, that could work. So it's just keeping it from shifting backward and forward or side to side, but it's not going to keep it in place top to bottom. That's probably what I would do with the hardware included.It does also come with a replacement fuse. It's going to be a 15-amp fuse. There's another bracket.

It'll come with plenty of hardware to get any of your L brackets attached. That fuse is going to go on the side with our other ports here, and again, we do get some instructions with our kit. This is everything that's going to come with our subwoofer. As far as the overall dimensions, this is going to be 15-3/4" long by 9-7/8" tall, and it'll be 3-11/16" deep. The subwoofer diameter is going to be 8".It's going to have a max wattage of 120 watts. The frequency response is going to go between 40 hertz and 160 hertz. The maximum current consumption will be 15 amps. It's going to have a signal-to-noise ratio of greater than 90 decibels and a input sensitivity of 80 megavolts. Out voltage is between 11 volts and 15 volts on DC power. This is going to be a nice system from Furrion to amplify that sound, give you a nice bassier feel with any of your movies or music and overall improve that sound quality in your camper or RV. That's going to do it for our look at the Furrion Indoor Enclosed Amplified Subwoofer.
