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.

Great Factory sub-replacement that was Sun rotted. This is a win-win situation all the way around and has a great price fits perfectly in the factory OEM bracket and sounds phenomenal. What a great recommendation again from my guy Champs

Amazed

2007 Toyota Tundra
Crutchfield Customer Review (What's this?)

I was skeptical when ordering this sub due to the size. I have. Stalled one in a BMW Z3 and another under the rear seat of a tundra. Amazed at the amount of bass produced. You are not going to get SPL out of their sub but I t will definitely fill in the lower end of your stereo and they are small enough to fit almost anywhere. Will definitely buy a couple more for other vehicles.

Pros: Great bass response and sound quality, fits in small spaces

Cons: None yet

Sounds good for the price. Fit in my 97 expedition. Had to take heat gun to back of factory enclosure to make it fit, but is fine. Works good with the factory amp too. Good replacement for stock sub.

I totally love this new subwoofer.

Nice addition to stock system

Crutchfield Customer Review (What's this?)

I bought this speaker to round out the sound in my daughters Kia Soul. The car came with the Infinity system which sounds great, but was lacking in the low end. The goal was to add a little deeper bass without being heard two blocks away, not take up too much space, and not break the bank. This speaker has fit the bill perfectly so far. I built a small sealed box that would fit into the storage tray in the cargo area to keep the speaker out of the way. Even in a smaller homemade box this speaker sounds great. If you are trying to irritate the neighbors, its definitely not the right speaker, but if you want to add a little extra bass, this speaker does a great job.

Cons:

Good build quality for price

Crutchfield Customer Review (What's this?)

I compared them to a RF Punch S1 and they are nice and tight sounding. A little bit tighter than the RF but have a great sound

Pros: Great value and great sound especially for a lower powered system. Lots of sound for the power.

Cons: Nothing really negative but the hole cutout does need to be slightly larger over other subs

Crutchfield Customer Review (What's this?)

Don't let the name fool you into believing that if it's not a big named product line that it must be cheap. Sound Ordnance is the only speakers and power amps I buy now. You can't beat the price and quality of their products. I've had them in my car for over 2 years with no problems whatsoever. I had everything professionally installed.

Pros: Overall build and Quality

Cons: Zero Cons

Sam from Virginia on 6/7/2015

Very good sounding speaker for the price , not only that you get a 3 year warranty with it as well, I don't have an amp hooked up to this speaker yet just breaking them in ,but it still sounds good.. I can imagine what it will sound like once i hook the amp. I like the wire hook-up to the speakers, just like the home style speakers.

Pros: Excellent Speaker

Cons: None

Great little sub!!

ELPQ35 from Kansas City, MO on 5/18/2015

Crutchfield Customer Review (What's this?)

This is a great little subwoofer. I purchased to replace a busted OEM subwoofer in my 2002 Ford Expedition. I read some of the forums only before purchasing and I have successfully install this subwoofer and the Sound Ordnance M2100 amplifier in the stock enclosure/location with very little modification. I was able to keep the original power and signal wiring as is but I changed the fuse in the amplifier to a 25A fuse to protect the original power cables. I did have to modify the original subwoofer enclosure. This 8" was too deep for the box b/c of the reverse hump in the back. Online someone said they heated it until it flatten out. I just cut the plastic hump out and filled it with a piece of MDF wood. I did not add any additional poly-fill other than the stock stuff that's in there. I measured the enclosure and it is roughly 0.6 cubic ft which makes it suitable for this subwoofer. Now this is an 8" so don't expect it to do any damage but it is a great upgrade for stock 8" subwoofers. I highly recommend. For the amplifier, I had to remove the shiny silver plastic by removing the screws and tearing off the decorative silver plastic. Fit well in original amplifier location with cup holder removed.

Pros: Great sound from small package

Cons: None

Crutchfield Customer Review (What's this?)

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

G-man from Denver co. on 9/13/2013

Crutchfield Customer Review (What's this?)

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.

3 questions already asked

no grill needs to be purchased seperate [ MARTIN  Dec 17, 2016 ]
No it does not [ John  Dec 16, 2016 ]
no grill [ james  Dec 16, 2016 ]
No it does not,its just the speaker and a rubber seal [ Edward  Dec 16, 2016 ]
No [ james  Aug 04, 2015 ]
THis was not an issue for me. I actually stripped the connections off to expose the wires, because it has a positive and negative. It sounds good in my 02 Tahoe [ DEMARLON  Aug 04, 2015 ]
I had no issue when I replace the Sub in our 2002 Avalon XL, just make sure you get the wires connected properly to match the impedance or the other speakers. It will work either way but will sound better if all are in sync. You will be able to tell by listening, if it does not sound correct just reverse the wires. [ Roger  Aug 03, 2015 ]
If you are saying your vehicle has two wires connected to the current subwoofer, then this unit will work fine. If your vehicle has 4 wires connected to the existing subwoofer then you have a Dual Voice Coil setup. Most aftermarket amplifiers will allow you to bridge the two outputs into one (two wires) for a SVC speaker. Some OEM radios will allow you to just connect one pair of speaker leads. If you have a DVC setup (4 wires) currently, you can find nice DVC subwoofers on the Crutchfield site. [ William  Aug 03, 2015 ]
NO this will not be a issue [ Anthony  Aug 03, 2015 ]
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 ]
