Tuned for maximum bass

Here's the bass — Boston Acoustics' G112PS enclosed subwoofer puts the rumble in your sound system, matching a G1 Series 12" subwoofer with a ported box that's optimized to deliver the most bass possible. The GTuned enclosure uses Boston's unique venting to increase bass output without adding the noise that inferior ports can cause. Boston Acoustics assembles and tunes the box in the U.S.A., and its 3/4" medium-density fiberboard construction offers extra strength and stability.

Connect an amp and you're ready to rock

The enclosure handles up to 200 watts RMS, and its 4-ohm total impedance makes it compatible with most amps. You'll get clean signal flow through the nickel-plated terminals, and heavy-duty carpeting protects the box and your car's interior. Place the G112PS in your trunk or cargo area, connect a compatible amp and wiring, and take your music to a deeper level.

Enclosed Subwoofers 101

An enclosed subwoofer is a box with a subwoofer already installed. The advantage to buying an enclosed sub is that the manufacturer made the sub, then designed and built the box as a perfect match, so you'll get the best possible performance. Every enclosed sub has a maximum RMS power handling rating, so pair it with an amp with a similar RMS power rating to get the best performance.

Features

Overview: The Boston Acoustics GTuned G112PS subwoofer enclosure features one 12" G112-4 subwoofer (4-ohms). The cabinet is made of MDF (Medium-Density Fiberboard) with glued dado ends.

Woofer Design: The G1 subwoofer has a copolymer cone with a raised polypropylene dust cap and a large foam surround. It features a wrap-around gasket which gives you a superior seal. The basket features the patented RadialVent cooling technology which directs the airflow around the 2" voice coil to increase power handling.

Terminals: The terminal cup is inset into the enclosure for a tight seal and a finished look. The nickel-plated, heavy-duty spring post terminals accept pin connectors, single or dual banana plugs, and bare wire up to 10 gauge.

Long Excursion: The woofers have a 1-3/4" peak-to-peak excursion for accurate deep bass output.

SureSet Protection: The input terminal is equipped with a 4-amp ATC fuse for voice coil protection under transient conditions such as accidental momentary overdrive. Use of the standard automotive style fuses allows you to quickly service the woofer in case a fuse is blown during use.

Note: The fuses do not protect against voice-coil failure resulting from long term high power abuse.

GTuned Port: Relying on a longstanding Boston technique, this GTuned enclosure features PowerVent tuning to deliver a perfect blend of extension, impact, and efficiency. The large port reduces turbulence and keeps your bass crisp, clear and deep, even under heavy use. The G112PS enclosure is tuned to 34 Hz.

This sub is not only good looking, it sounds amazing. I have the sub in the trunk of my 2005 mitsubishi galant. it is paired with a Boss mono amplifier. I have it secured with heavy duty velcro straps underneath the sub. The bass comes out very smooth, deep and acurate. it blends seamlessly with the new speakers inside the car. Im very happy about this sub. My next door neighbor is amazed at the sound, and the price. He has put in his order!!!.

Pros: Great Look, High Quality, power handling says 400watts peak, but this thing can jump beyond that. but there is no need to feed it alot of power because the massive side port opening can move alot of air and you can get very deep bass with around 150 watts or less.

Cons: NONE!!!!!

Lots of thump

This sub is a great value. The bass is powerful enough to get through the sealed truck of my Honda Civic Hybrid. It is however, a ported enclosure and therefore suffers the typical limitations of an open box sub. While there is plenty of thump to let you know it's back there, it lacks some of the crispness of sealed box unit. It can get a little wattery with poor quality input. Feed it from a clean head end with quality content, and the unit shines. You can't beat the bang for the buck with this sub.

Pros: - good punch - doesn't require huge amps to get good sound

Cons: - ate up my trunk - not as crisp as a sealed box sub

Fantastic Product!

I recently purchased this for my 2003 Camry because i could not pass up the insane deal. I an running it on a Kicker Amp at 200 RMS through the JBL stock head unit (with the aid of a LC2 converter) and it sounds absolutely perfect. All together cost me around 250, you just can't beat that.

It's critical to have good wire, and none is included with the sub.

Keep your sub from rolling around in your trunk by using mounting hardware.
