As expected

Could have a better way to decide which wire to use as positive or negative. Only has spaced print on one wire.

Great wire

This is some great speaker wire looks good works good and you get so much for so cheap

Awesome

Great wire, for a great price! Love the color and looks very professional.

Good value

It’s listed as (cca) which is copper clad aluminum wire and is cheap and doesn’t hold up good to high wattage. Aluminum isn’t the best audio wire, but it is copper clad and electric signals travel on the outside of the wire and that’s where a multi strand wire would come in handy. I think it’s a judgment call, but I wouldn’t buy it.

ESSENCIAL NEEDS

WOW HOW VERY FLEXABLE AND THE RED
REALLY GAVE SOME KILLER LOOKS. WIRE
VERY GOOD.

Decent speaker wire.

Speaker wire is good. It works as speaker wire should.
My only grief with the wire is the thickness of the insulation. It's really thick, and in my opinion, too thick.
I have a very high quality wire stripping tool, but the thickness of the insulation made it next to impossible to center the speaker wire and my stripping tool always cut a bunch of strands of the wire. Not a real big deal in the grand scheme of things, though.

Great Product

I bought this for my son and they sound great!

Great buy!

Good sound for the money. I didn't want a stereo to rattle windows and that's what I got. It hits hard on lows for a shallow mount ten running a 500 watt alpine amp it pushes them to hard but they're not made to handle as much power as it produces once tuned right I believe anyone would be happy with this product. I'd buy again!

rockford fosgate r2sd4-10

this is a good sub for not a lot of money and fits great in a truck cab

Love It

I was looking for a small amount of bass without taking up much room. I installed one of these in a custom sealed box with polyfil in the back of my Toyota Supra. The bass is very clean which I expected, but I did not expect it to get as loud or as low as it does! Really gets down for a shallow 10. Nice product.

Excellent product

This is a top quality product and has made a world of difference in my e46. I needed something that provided noticeable bass but wanted to limit the boot space lost. This also fits nicely into the ski pass when the box was mounted. I would highly recommend.

No space? Get this sub

Bought the DVC 10" sub, built a box that fit under the rear seat of my avalanche. Due to having limited space, the box just barely met Rockford's minimum cu.ft. recommendation. I was pleasantly surprised. Hits much harder, smoother, and cleaner than a factory Bose system. Just what I wanted. It won't go as low as a bigger sub, but I am not disappointed at all.

Great value

The sub box is compact and clean looking. Fit great in my boat. Highly recommend.

Great experience

Effortless ordering and install process!! A great overall experience and would recommend to anybody! Sounds great!

Great, perfect fit.

Read online about putting these in the rear deck of my M5 replacing the stock sub box. Using the stock amplifier . Amazed at the result and the price cannot be beat. If you are considering a bass upgrade to your E39 keeping the DSP I highly recommend these subs for that.

Excellent Sound, Incredible Bass!!

Installed two in the rear of my E39 BMW powered by factory DSP Amp. Kicked my sound into High gear!
I LOVE them!

Worth the price for sure

Good quality item and definitely worth the price. Definitely recommend

Great buy!!

This box is built right and is high quality. I have a kicker 10 compRT in the box and it thumps hard. For anyone looking for a good single 10 enclosed box then I would highly recommend buying this one.

Good deal

I bought this as a gift for my brother. He loves it. Works perfectly for what he needed.

Great price

I would recommend this product because it gives great protection from the elements and makes a nice enclosure for the speaker.

belva 8ga BBSW127

I liked the quality very much and the cable was very flexible which made it easy to run.

Good quality cable

This cable which I got for free with the purchase of a Belva Sub-woofer box is pretty good. Nice 12 ga. cable with a very nice outer insulator. Nice and flexible.

Plug and play

Just what the product description says and it does it. No complaints here!

Exactly what I needed

This is great speaker wire, and at a great price. Very happy

By Gerald on February 20, 2016 Verified purchase

Great deal

Have always bought from your web site. Very easy to use, with great pricing.

Shallow Mount Subs, WOW Impressed

I was told by so many who think they know it all that these would sound like crap or don't get them or since you have a 4 door truck they will sound horrible, well guess what they are MISINFORMED, these sound awesome to me! I am a 46 year old who likes good country music and these speakers give just the sound I wanted!

Sonic gave me the right price!

Great product & Great price

I highly recommend this product and suggest you check out their other items.

10" Rockford Fosgate

I would recommend this subwoofer great price and great sound.

Limited space ?, these are the right choice

for those have only a limited space, this are the brilliant choice without scarify the quality/power of the bass generated !

awsome quality for the budget!!!!!

I have it on the back seat of my f-250 diesel crew cab. It sounds and feels real good.. I'm very happy with these purchase. Big difference, and just right!!

wire

Pretty colors. NO issues with this wire but how bout a kit with the nice bullet ends so they can go into the AMPS real perty like and I don't have to hunt and peck for them and/or some colored heat shrink wrap so you know which one is + or - easier.

By Danny on September 30, 2022 Verified purchase

Better than I expected

If you're looking for a shallow mount sub, look no further, this thing truely slams, took at least 600 watts with no issues at all, ran it that way for a while, I'd say this is an underrated subs, I've honestly been shocked by how happy I am with it.

Rockford Fosgate R2SD4-10

Installed two of these 10" speakers in my F150 supercrew, in a box under the rear seat. Way more bass than I need, but way excited to listen to it thump!

Awesome low profile sub

Bought this because it was one of the few subs that would fit under the rear seat of my 2012 Ford F150. Having used it for 6 months now I can say I would gladly buy it again. It doesn't shake the paint off the doors but that was not what I was looking for. I replaced all the speakers and used an Alpine amp for the mains and a Kicker for the sub. It took the sound from horrendous to really very good for very little cost.

The Car Guy

Execellent sub I am currently running two of these subs with the 1000 watt Kenwood 2 channel amp and they pound. I am very pleased with these purchase. Like I said before I love kenwood, they make kenwood and rockford fosgate what a great combination. If you want good deep base buy these combo, the price is right and your friends will envy you.

wow

I have been around car audio for about 20 years. A huge Rockford fan but Iwas out of it for the past 5years. I purchased a 2013 mazda speed 3 and wanted good tight bass. Didnt want to go with the shallow woofer but didnt have a choice. Built a nice box with reommended cu ft. Along with a new soundstream mono 450 amp. I have installed many high end systems and by far this one really puts a smile everytime. Rockford always produces never a doubt.

Good service

Good service and priceing shipping was great and fast sub didn't end up working in my car don't think my car has the power to use it

Great buy

This is a great bye for a shallow powerful subwoofer

Best shallow mounts for the money

Bought two subs to mount in the back of a standard cab Chevrolet. These were the biggest subs I could mount in the limited space. They sound FANTASTIC! They hit much harder than I had anticipated. I would definitely recommend these to anyone with limited space.

Awesome!

I bought two of these for my 2006 Extended Cab Silverado and hooked them up to a 1200 watt 400 RMS amp. I have to say that these things are amazing for the price you pay! I was limited on space so I had to go with shallow mounts and I am very impressed with the performance of them. I would recommend these to anyone who has a limited budget and still wants nice, clean bass. Make sure you get the right amp for them though!

Good product

I got this speaker so I can have a little base in my late model hatch. so far I am very happy with it. I hooked it up with a cheap amp and I'm very impressed with the bass quality.

Awesome

Highly recommended. Great sound great value great buy! Love this seller!

RF-R2SD4-10 review

Great sub for the money $$$$. Have two in a 2500 ram and the sound is excellent. Fast shipping from vendor as well.

Nice Subs for Compact Box

These subs will deliver some nice bass notes, I have had them in a smaller box .5 cubic feet and a larger .75 (per sub) sub boxes and they sound great in both. I love Rockford Fosgate subs this is my third pair and they can be driven hard with no problems!

By Anonymous on December 16, 2018 Verified purchase

great product

I have 4 of these subs in my truck and they work great very satisfied with them

Love this speak I have 1 single 15 powered by a 2500 watt earthquake class d and it absolutely bangs can't go wrong with this subwoofer it has clean sound and can take power well

Rockford Fosgate Prime R2SD4-10

This is a very robust woofer. I really beat this subwoofer up and it took it like a champ. The only reason I bought it was price. It lasted for two years of abuse. I had it over powered 300 watts on a 200 rms and never skipped a beat. It played better the more I abused it. It might have been the enclosures perfection but I do recommend the subwoofer if you are on a budget. Also my enclosure cost 3 times the woofer so please keep that in mind when making your decision.

Great product at a great price, Rockford Fosgate never disappoints.

great for small places

I just put one in a downward-firing sealed box that is under the backseat of my truck. total is less than 6 inches high so the seat can be let down without removing it. Sounds good especially for an entry-level sub. and for a sealed box about 0.5 cubic feet. so far it handles more than expected and is loud for the size. I am running it off an NVX MVPA1 200 watt RMS at 4 ohms. Handles it well without distortion. This is exactly what I wanted as far as adding bass. It isn't a competition sub but great for an everyday vehicle.

For the money its great!

This shallow subwoofer has surprisingly good deep bass. Would recommend. Pretty cheap too.

By Carlos on January 2, 2016 Verified purchase

amazing and cheap

i replaced the original speaker wire in my car with this and the difference is just crazy and this wire is really cheap so it’s definitely worth it. it’s a nice color and is very easy to work with.

By tart on June 1, 2024 Verified purchase

Solid Value!

12 Ga speaker wire, with great insulation, for this price? I was skeptical at first but after hooking everything up I can say that this wire is fantastic, and much better value than Walmart/Amazon. 23ft for $7 of high quality wire? No brainer.

Basic Speaker Wire

I like the pliable insulation on these wires. It also strips very clean.

By Eric on May 15, 2024 Verified purchase

Great wire for speakers

I should’ve ordered more wire it’s the perfect gauge for what I’m using it for subs and my coaxials

Good for the price

Nice carpet, can't see any seams. Nice clean look. Sturdy enough for what you're paying for. My only complaint is it did not arrive when it was supposed to. Not even close. That's NOT the fault of Sonic Electronix though, it's FedEx. FedEx is the worst. Nothing but issues, delays, they left the package next to a tree in my front yard. I have a 700 foot long driveway. Attention all online retailers, please don't use FedEx.

Solid speaker wire for the price

This is great speaker wire for the price. Has a nice protective jacket and very flexible. I usually stick to OFC wires but for lower wattage speakers and line output converters this is perfect!
