    • Feeling the audio instead of listening.
Quick and easy setup, tied high pass filter into the rear speakers for the signal. Don’t even need to pull stereo out of the dash. Power line to battery is only challenge. Dollar for dollar the performance is out of this world.

    • Surprisingly bassy subwoofer for being compact
The media could not be loaded. I originally bought this speaker from Amazon as the seller for $20 cheaper since it was “refurbished”. Well that was a mistake. I already had bad vibes as the original box was all beat up and the speaker box itself was covered in dog hair. I plugged it in and quickly noticed that the speaker was blown. I checked and tripped checked my wiring and messed around with some of the amp settings and nothing helped as it was obviously blown. Returned it and took a chance on a new one and boy was I not disappointed. I highly recommend getting a wiring kit to make your life easier. Just search - BOSS Audio Systems KIT2 on Amazon. The kit comes with all the wires you need and the quality and gauge is suitable for this speaker. The speaker box is solid and the embroidered logo is a nice touch even though I’ll hardly see it under my back seat. I like that the grill gives enough room for the speaker to move while still allowing it to be protected while cramped under the back seat as you can see in my video. The controls on the amp give you volume gain and frequency response adjustment. My only complaint is that I wish the gain on the box got cancelled out if you plugged in the volume remote knob. You have to adjust the gain on the box properly so that your remote has enough gain that it won’t overload your speaker and possibly blow it. The bass produced won’t win any competitions or annoy the neighboring car at the light but it does produce enough to feel punchy in rock music and rich and deep for hip hop. It definitely fills my truck cabin with all the bass I need making my rides more enjoyable. Now, the question is going to be how long will it last? I’ll update my review if I have any issues. ... show more

    • Great Amplified Sub.
I purchased this product January 22, 2017, and it has been a great unit. I installed it with a Scosche 1200 watt amplifier/subwoofer kit you would buy at Walmart and have had no problems with it. It is installed in a diesel pickup with dual batteries and has all the power it needs. I let the subwoofer break-in for over a week, I turned the gain up just until the woofer started to tremble and probably put over 24 hours collectively into the break-in period. I have the gain turned to about half (after break-in) and it produces some extremely impressive bass for its size in my opinion. I have had no overheating problems as some other reviews elude. My install sandwiched the amplified sub between the back seat and the back of the cab and there is very little ventilation, yet it does fine. If you have a head unit that has bass boost and frequency (Hz) options only CHOOSE ONE to be active at one time (bass boost on but Hz is off, etc). Overall, I think this is a great unit when space is premium and I believe this amplified sub is an extremely great price for what you receive. Just install it correctly, give it the power it needs and most importantly let it have time to break in. ... show more

    • Great for some added bass
I was skeptical about this sun at first but after I had it installed it blew me away for the price of this 2 in one package.If your looking to blow the doors off your car or rattle the neighbors house you’ll be very let down and might want to find something else.If your someone like me who was looking to add some crisp sound/bass to your music you’ll love this.I have it installed in my 2008 Nissan Altima 4 door sedan and it fill the cab amazingly.Big difference from no sub if you listen to rap,country,or party type songs.If your into rock/metal it won’t add to much bass.It’s still sounds a lot better than not having one since the stock door speakers can create the bass this sun can.I think If you have a smaller car or a single cab truck this would be more than enough for any type of music.If you have a bigger vehicle would would look for something else.I have had this sub in my trunk for 2 months now and I love the way it sound and would get another one tomorrow.Another thing is it takes up almost no space in the trunk leaving tons of room for what ever you need to lug around with you.For the price size and simplicity of this built in amp subwoofer it has great value for the money.It sound better than my Lincoln with the premium sound system in it.Hope this helps I tried to give the most honest review to help you make a decision.Cause when I was looking I scrolled through hundreds before I made a decision. ... show more

Forgot to write a review but had this in my sequoia for 2 years without issue. Added just the right amount of bass. And was easy to install. I loved it and plan on getting another for my new car

    • False Advertisement...Item is Not Even Close To Black....It is Grey...WTF?????
Review Image by Taylor Taylor
First off I would like to make it very clear. This item is not black! It's actually grey. I was very disappointed to find out that they sent me something other than what I expected/PAID for. I purchased this item. Zoomed in to see color and quality. I liked what I saw so I purchased it. Received the item and had it professionally in stalled. Keep in mind I never opened the box when I handed it to installer who doesn't sell this item. When I heard the sound it sounded like a new sub and it did give me a little extra bass which was desired. The first time I laid eyes on it I wasn't happy. If I wanted grey I would have went ahead and purchased the kicker setup. This does not hit hard so please don't get your hopes up. The item is well made but cosmetically the listed item is not accurate at all. Do not purchase this item expecting black carpet because it is Grey. The customer service contact has made me mad. Telling me to return the item as if it is a floor mat in the vehicle. I took pictures of my install and now you are telling me to remove the wires and return it. WTF?????????????? I will never purchase another item from this company. Trust me... I will do my best to ensure people know Amazon has this item listed but it's not accurate. GREY...GREY....GREY.....GREY.....GREY.....GREY....GREY....GREY!!!!!!!!!!!! ... show more
