LOPRO10 10 Inch Powered Under Seat Car Audio Subwoofer

Deep Bass Low Profile

Enjoy the rich sound of Bass in just about any vehicle with the SSL LoPro10 Class A/B 10 inch Low Profile Amplified Subwoofer. With 1200 Watts Max Power and MOSFET power supply and High and Low Level Inputs, this Amplified Subwoofer can be hooked up to just about any in-dash stereo. With a height of just 3 inch, it's a perfect solution when space is an issue as it can easily fit under the seat of most vehicles. Customize the sound with the Variable Low Pass Crossover, Subsonic Filter, Phase Control and Remote Subwoofer Control.

Break Your Subwoofer In

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.

    Excellent powered sub!
    I was skeptical about the quality of these powered subs before my purchase. I spent almost 4 x this price on another brand of powered sub for the back of my Alfa Romeo suv. I then bought 2 of these for under the front seats. I installed all 3 the same day. These are amazing, sound just as good as the way more expensive one I bought. These are so good that I only run the front ones at 1/4 of there volume because thats plenty for me. It’s hard to describe because the base with powered subs vs a big box that were all used too is not the same but in many ways I think these are better. When there isnt much bass in a song you don’t feel anything. Then your seat comes alive with every little rumble, but not in a way that effects the other highs and mids. Really great, I wish I’d bought these years ago!

    This is not necessarily a great subwoofer, but it is a great value. As others have said, this is not going to put out enough bass to hear outside the car. In fact, I would be hesitant to buy this if I were installing it in a trunk. However, I was looking for something small to fit under the passenger's seat in my 2015 WRX that would fill in the lower frequencies of my factory system and this worked perfectly. It took me about 2 weeks of tweaking the levels to get it setup correctly. Once I had it dialed in, it blended with the rest of my audio system very well and now sounds like I have a much more expensive audio system than I actually have. I did end up hiding the remote in my glove box so I would not have to look at the absurdly bright blue light, but that's not a big deal because I rarely need to adjust it.

    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.

    Sound Storm Laboratories LoPro8 Installation

    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.

    Tenia mis dudas por la opiniones negativas pero el resultado fue excelente. Lo instale en el asiento trasero de una ford lobo doble cabina y transmite un sonido fuerte, nítido y suficiente para escuchar música dentro del vehículo, de hecho te sorprende lo potente del bajo a pesar de las dimensiones del cajón. La calidad de los materiales es de primera y su precio es también de lo mejor; opciones de la competencia como db drive o cervin vega son el doble de costosas. Finalmente decir que si buscas un sonido fuerte y justo para sentir un bajo dentro del vehículo, esta marca es una excelente opción. Lo recomiendo ampliamente.

    It has exceeded my hopes. I'm blown away by the quality and how clean the bass is. There are brand names that cost over $100-300 more but why get them when this is under $200. I got it professionally installed and it sits underneath my drivers seat. I don't have to have the gain up or need to turn the volume on high to have a broad range of clean thumping Bass. It rattles my car but doesn't shake it apart. I'm highly satisfied and am giddy each time I'm driving and hear it. One is totally enough to compliment my 4 Rockford Fosgate speakers and Sony deck.

    Very good subwoofer for the size, I am very impressed with it. Only complaint i have is the remote gain is very sensitive, doesn't take much to turn it on full or full off
