Add some boom to your ride

Win the battle for boom with subwoofers from Sound Ordnance. Throw one or two of these bad boys in your vehicle to give you bass you can feel. You'll love the difference these subs make, and adding them to your system won't destroy your budget.

Built like a tank

The M2-8SVC 8" subwoofer comes with a tough glass fiber cone that will keep its shape when the music's turned up, so your bass stays accurate. The butyl rubber surround helps keep the woofer's movement on track, and it'll stay pliable for years to come. The stamped steel basket provides a stable home for the whole assembly, so your bass plays the way it should. Also, Sound Ordnance backs up this sub with a 3-year warranty, giving you peace of mind while you're rocking hard. 

To drive this single subwoofer, we recommend a mono amplifier rated between 120 and 225 watts RMS at 4 ohms. For more information, please refer to our article on How to Match Subwoofers and Amplifiers.

What's a component sub and why would I want one?

A component sub is simply a speaker that's designed to reproduce bass once it's installed in a compatible enclosure. Think about the impact of a movie soundtrack in a big theater or even in your own home HDTV setup. A component sub can add the same kind of power to the music in your car. And a car sub is not all about the boom that you hear on a street corner (although that's cool too) - you can pair a component sub with your choice of enclosure to get bass just the way you like it, from tight and punchy to fat and loose. And once you experience music in your car with a well-tuned subwoofer, you'll never go back.

I am using this sub in my 2000 XJ in the Select Increments XJ-Pod 8" Subwoofer box (sealed) for 84-01 Jeep Cherokees. The sub is powered by the Sound Ordnance M-1350 amp and the head-unit is the Alpine CDE-153BT CD Receiver. Together, it sounds great and I wish I had done this years ago.

Pros: Great sound, better than I expected out of an 8" sub, especially for the price! I really like S.O.!

Cons: None

I needed some bass in my old vehicle and did not want to spend to much. Called up and spoke to the rep and he suggested the 8" for my application, due to using my old amp for power. Crutchfield is great because they helped me figure out how to bridge the amp that I bought from them in 1999. Lifetime support baby! Anyway, got my sub, built a box to fit under the passengers seat and hooked everything up. It sounds great! Fills in all the sound and thumps like my old 10" sub that I used to have in my truck. My kids love the sound system, and now we have a great time in the car listening to all types of music. Next I'm upgrading the stock door speakers. What will I buy? Sound Ordinance components.

Pros: Full sound with little space

Cons: So loud, could hurt your ears. But that's why I bought it.

It's critical to have good wire, and none is included with the sub.
Reduce ambient road noise and your vehicle's "rattles," for better sound inside your car.
Add a grille and keep your sub safe.
These can be useful if you are building a custom box.

Mitch, I replaced the factory sub in a 1998 Ford Expedition. The factor amp was existing and I would assume the crossover was built into the amp. I would say yes you would. Good luck. [ TIMOTHY J  Mar 19, 2014 ]
I didn't I just hooked it up to my stock stereo in my Chrysler 300 class c and it sounds great! [ DEAN  Mar 18, 2014 ]
