About this item
- BUILT-IN AMPLIFIER: With a MOSFET power supply you get improved switching speeds, better performance with less power from the driver, lower gate-to-drain feedback capacitance, lower thermal impedance for higher switching frequencies
- VARIABLE LOW-PASS FILTER: A low-pass filter is an electronic circuit that removes all the notes below the filter's frequency setting. You will use the Low-pass filter to primarily keep high notes out of your subwoofer(s)
- HIGH LEVEL INPUTS: Speaker level inputs are commonly referred to as high-level inputs. It will be used to connect the LOPRO8 to your factory radio or an aftermarket radio that does not have low-level (RCA) inputs
- LOW LEVEL INPUTS: Line level inputs, also known as RCA inputs or low-level inputs, use RCA interconnect cables to link the LOPRO8 with the source unit. Most aftermarket radios have multiple pairs of RCA outputs that can connect to multiple amplifiers
- VARIABLE BASS BOOST: Variable Bass Boost allows you to adjust the low bass within the boost range to just the way you like it
- DIMENSIONS: 15” x 9.75” x 3”. If you are short on space, this is a great solution for you. The combination of amplifier and subwoofer all into one, makes this ideal for spatially challenged vehicles

Built-In Amp and High and Low Level InputsSystems with a built-in amplifier do not require the addition of an external amp. They already have the power to play louder. 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. |
MOSFET and Class A/BMetal Oxide Semiconductor Field-Effect Transistors quickly switch from full to non-conduction for high efficiency output. Our Class-A/B amplifiers feature specific linear circuitry that increases sound quality and power output while reducing distortion and improving efficiency. |
Variable Low Pass Filter and Subsonic FilterVariable low-pass filter gives you control over the frequencies that pass through to the subwoofer. Subsonic filter restricts low-frequencies below the specified setting for better subwoofer protection and performance. |
Subwoofer Level Control and Bass BoostA wired remote lets you easily control the subwoofer level for customized output and superior sound. Variable Bass Boost allows you to adjust the low bass within the boost range to just the way you like it. |

Short ProtectionAutomatic shut-off protects the amplifier if it gets too hot or if speakers fail causing a short. |
Phase ControlPhase control lets you switch the speaker phase with the amp if your speakers or subwoofer are hooked up 'out of phase'. |
Low ProfileLow-profile subwoofers are a great choice for space-constrained areas without compromising on power and performance. |
Variable Input ControlThe Variable Input Control allows the amplifier input to match the output signal from the head unit to achieve optimum performance when adjusted properly. |

April 2014 – I installed this subwoofer in a 2014 Honda Accord Plug In using the stock radio and navigation system that came with the car. The subwoofer was placed under the passenger seat with a little room to spare as I wanted to keep everything as stealth as possible. This subwoofer has a built in amplifier and various controls for great bass and gives the music the extra punch it needs. I’m amazed this subwoofer doesn’t have a port but can still produce deep and strong bass levels for its size. I bought mine new from Amazon at $113. It’s near impossible to get to the back of the car radio without dismantling the entire dash so I chose not to do that and created an alternative to share.
Before you get started, safety first. Be sure you put electrical tap on all exposed speaker and power wires. Be sure you put electrical tape in any area where they might touch another wire or connector. Wrap electrical tape around wires where they might rub anything and expose bare wire later on. Don’t add power to the subwoofer until you’ve double checked your connections and ready to test.
For subwoofer power, I bought a 20 amp buss fuse holder at Home Depot and attached one end to the positive battery post. Use the battery in the engine, not in the trunk. Then open the passenger front door and there’s a plastic vertical panel next to the door hinge covering access to the quarter panel wheel well. I pushed a red 8 gauge wire through there to above the front right light assembly, then well above the radiator around the left light assembly to the battery. I attached the other side of the fuse holder to this wire. NO FUSE INSTALLED AT THIS TIME.
Passenger front seat – foot area. There is one horizontal panel just above where the feet would be. That pulls down. The kick panel is that horizontal panel you step over when you enter into the car. That pulls up. There’s a vertical panel just right of the feet and that pulls off.
The passenger door has a black rubber boot that feeds wires from the cabin. I made a small cut in the boot on the cabin side and fed the red power wire through the boot. I followed the existing wire harness along the kick panel and the wire comes up under the passenger seat. I patched the cut in the boot with some caulking. For the ground wire, I used black 8 gauge wire and attached it to the passenger seat mounting screws.
This subwoofer has a third connection that tells the subwoofer to turn on when the car is turned on. Otherwise the subwoofer would have power all the time and drain the battery. I took a 12 Volt cigarette lighter charge adapter and cut the end off the cord. I ran the 12 volt power side to the subwoofer Remote connection. Do not connect this to the Remote Level Control on the other side.
For speaker input, the subwoofer can use low end RCA cable input or high end speaker input. I chose the high end. At the passenger kick panel noted above, is a wire assembly. You’ll find a solid blue wire and solid orange wire, the rear right speaker. Splice in a 10 gauge speaker wire to these and route the rest under the passenger seat. I could not locate the left speaker wires so here’s my fix. I ran 10 gauge speaker wire from under the seat, to the back seat of the car, through one of the top child car seat anchor points to the left speaker. There, I put female spade connectors on the ends. About 2 inches back, I stripped the insulation off, and attached 3 inch leads with male connectors. I pulled the speaker connector off the speaker. I put the female connectors on the speaker and male connectors on the speaker connector.
At this time, from under the passenger seat, you should have a red power, black ground, 2 speaker wires, and a cigarette adapter line.
At the subwoofer… connect the speaker lines to the supplied connector. Be sure your polarity is correct. There is an extra ground wire on the connector, be sure to connect it to ground. Attach the red wire to power. Attach the black wire to ground. Be sure your polarity is correct here too. Go to the battery and install the fuse. Install the Remote Level power adjust cable and control. DO NOT CONNECT THE 12 VOLT CIGARETTE ADAPTER yet.
HINT: Be sure your speaker polarity is correct. Using a spare speaker, you can attach one line to the speaker and ground the other side. Turn on your car radio with low volume. If you hear speaker sound, then that is the positive line. No sound, and the speaker hook up is the negative side. Turn off the car power.
On the LoPro8, set the controls like gain, boost, etc to very low. Be gentle when turning. Turn full clockwise. Then turn full counter clockwise. Then turn clockwise about a quarter turn, about a 3 o’clock position. Do this to all 4. Do the same for the Remote Level Control. Power on the car. Power on the radio. Turn the radio volume to low. Now connect the cigarette adapter and look for a green light to show on the subwoofer. Look and smell for smoke and sparks and shut down immediately if you see these. Put on your favorite song on the radio and turn the volume up to just above where you can hear it. Adjust the Remote Level Control, volume of the radio, and the Gain first in small steps. Then fine tune using the other adjustments. For a few days, I placed my subwoofer on a box and kept in on the floor in the back seat until I could adjust the subwoofer settings just right for me.
Before putting the unit under the seat, double check that your connections are tight but don’t overtighten where you’ll break something. Be sure to use electrical tape where you see exposed wires. There is a vent under the seat. I used a curved strip of aluminum foil to deflect the air around the subwoofer. When you push the subwoofer under the seat, don’t bind or pinch the wires. If the music still sounds good, and you don’t see or smell sparks or smoke in the car or engine, you can put back the panels you removed.
The LoPro8 packs some good bass and extra punch to the Honda radio. I can see the rear view mirror vibrate when I have the volume up about 25; it goes to 40. Sometimes I like to play the music loudly and the LoPro8 is a great unit for the size and I am very pleased.
Problems… The Honda radio has 2 microphones that listen to the noise in the car as it goes faster. At around 40 mph, rough roads, or windows down and cars rushing by, it causes the subwoofer to sound off on its own. I haven’t tried disconnecting the microphones yet. Secondly, the cigarette lighter adapter used to power on the subwoofer may need to be adjusted to something under 12 volts as it causes a slight pop on the subwoofer when the power is turned off. An easy fix with an in line resistor.
When I first ordered this subwoofer, I was a little concerned about quality from other people's reviews, specifically it overheating easily. But I have been using it for about 3 months now, during the peak of Florida summer heat, and I have not had a single issue. I do have the gain set around 30% of its max level and the bass boost turned way down as well, so I'm not pushing the amplifier as hard as others may. But at this point, I would be surprised if it failed on me for any reason.
I have installed aftermarket sound systems in every car I have owned over the past 15 years so I have a lot of experience with car audio equipment. I don't think there is a better compact subwoofer/amp on the market at this price point. I'm sure there are better options, but I would expect to pay 3x-4x as much for one of them. If you want to fill your car with the type of bass that drowns out all other frequencies, this is not the subwoofer for you. But if you are looking for something that will provide balanced bass at louder volume levels and hit lower frequencies than your door speakers can support, you will be hard pressed to find a better value.
For anyone considering installing this in a 2015+ WRX, it is a perfect fit under either seat. There are pre-existing cutouts in the carpet to run the wires through, as this is where the premium factory system places their amplifier. You will have less than 1/4" clearance between the seat rails, so the 10" subwoofer will not fit. The seat heaters are a few inches away and would likely have no effect on the subwoofer's performance. I recommend pointing the speaker towards the floor to insulate the seat from excessive vibration. I used an 8 ga amp kit, but only because I already had one. A 10 ga kit will supply enough power. You will need a line-out converter if you have the stock head unit. I used the PAC SNI-35 and it has been great. The sound quality is better than most and it fit behind the radio so I could leave the RCA cables there for when I do upgrade my head unit.

If your system has a sub out with controls its top notch.If its undistorted bass for those ears in the car (hatch back) its more than enough.More over its got all the controls on the sub that one needs and you also get a bass control to fit close to you to adjust for every song should you need to.
The seller is prompt n responsive and i had no issues. In fact i got it nearly a week earlier than the expected date and neatly packed too.
