Description

Much like the engine of a new automobile, a new subwoofer must go through a short but important process of “break-in” before it is run under harsh conditions. The “break-in” process will ensure the subwoofer is able to perform as it has been designed to. This process involves subjecting the subwoofer to no more than low-to-medium volume levels for a number of hours in the enclosure. 3-4 hours is generally sufficient for the subwoofer’s suspension to loosen enough to prevent the voice coil(s) from overheating and causing failure. The break-in period is also effective in extending subwoofer life. Over-driving the woofer before it has been properly broken-in will usually result in premature failure and poor performance. Systems with a built-in amplifier do not require the addition of an external amp. They already have the power to play louder. Our Class-A/B amplifiers feature specific linear circuitry that increases sound quality and power output while reducing distortion and improving efficiency. Metal Oxide Semiconductor Field-Effect Transistors quickly switch from full to non-conduction for high efficiency output. High-level inputs accept speaker output signals and low-level inputs accept pre-amp output signals to allow for the addition of amps and processors to standard factory or aftermarket source units. This comes in handy if you are installing your subwoofer with the magnet facing out. Reverses the polarity (Positive/Negative) on your subwoofer terminals to reverse the direction of the low frequency BOOM that you are used to hearing. Variable Bass Boost allows you to adjust the low bass within the boost range to just the way you like it. Variable low-pass filter gives you control over the frequencies that pass through to the subwoofer. The Variable Input Control allows the amplifier input to match the output signal from the head unit to achieve optimum performance when adjusted properly.

  • Good bang for the buck
This sun sounds pretty awesome. Especially at the price point of $160ish bucks. Now, I have found that since the enclosed box is only 7 inches thick at its widest point, this bass is a littler tighter sounding than my previous 12 inch Rockford discard enclosed sub in my old car - that one rattled the mirrors a little more. This one vibrates the rear view mirror a little, and I can still feel some bass. For an SUV cab, it’s plenty without hurting my ears and can still slap. I also went with the low-profile enclosure so it doesn’t take up much storage space. Overall a very good subwoofer purchase. I do wish it came with a detachable wire hook-up plug like my old Rockford fosgate did when I needed to remove it for storage space. But I found Scoche sells one for about $20. If you’re looking for a powered sub for under $200, this is a fantastic options ... show more

  • Its worth the price
The sound quality is excellent for the price point. It was relatively easy to install. It is a bit bulky and doesnt fit well in my RAM 1500 but once I mount it to the floor board between my front and back seat it should be fine. The kit doesnt come with all of the wiring, you have to buy it separate. I bought a wiring kit from Walmart for $25 which worked out well. The subwoofer comes with a durable box that should last quite a while if taken care of. It hits pretty hard in that small space. ... show more

  • Not as good as the description
Doesn’t fit the space because the dimensions do NOT include the sub sticking out of the box…the dimensions are just for the box. Not very powerful at all. does not adjust properly. Sounds fine but low end.

  • Works great!
Haven’t had any issues, I work in parts sales and I already know 99% of electrical issues are user error and not because of the product. This seemed pretty simple to wire especially since the amplifier was built into it. Instructions could’ve been a little more easily explained but I got the point of them and have had it for a few months now with no issues. ... show more
