More than enough bass!

The following review is for R2S-1X12, which is a part of the bundle you are viewing.

Dropped this under the seat in my F150 pushed by an old school Punch 75 and boom, clean manageable bass. Doesn't hit as low as my dual 10's but is real clean. Great value and fits nicely.

Very good slim fit unit

The following review is for R2S-1X12, which is a part of the bundle you are viewing.

I put this unit behind my 2018 tundra it was a tight fit but I got it in there after having to unbolt the 2nd row seat. For a shallow box this thing does the job If you have tight space I highly recommend this sub. I wish I could of got 2 of these subs behind the seat but 1 would only fit.

Best bang for regular cab

The following review is for R2S-1X12, which is a part of the bundle you are viewing.

Very impressed with the pair of these behind the seat. They run in series off a Rockford Fosgate 500 watt mono amp and I have been quite happy with them. I don't know how you could possibly do better for the money.

IT fits behind the rear seat of a Chevy c30 crew cab

The following review is for R2S-1X12, which is a part of the bundle you are viewing.

Because of space limitations and availability of premade shallow subwoofer cabinets that would fit the limited space I had , this was a perfect fit! Additional bass is great from this speaker- Don't expect you'll crack house foundations with it but if you want improved bass response in a compact package - ESPECIALLY in a Chevy/GMC squarebody this is your kit- IM running a Memphis 300watt@ 4 ohm amp to power it .

It fit perect behind the seat of my ranger

The following review is for R2S-1X12, which is a part of the bundle you are viewing.

I needed something to fit behind the seat in my single cab ford ranger. This was perfect and i got to keep my leg room in an already small cab. Unfortunately i had to give up the low bass though. previously i had a kicker comp in a ported truck box, and a 500 watt jl audio amp(still using the same amp) and i was pushing much more bass with a good range from highs to lows but the box was 2-3 times the depth as this box and made it uncomfortable to sit in the truck with the seat that far forward. This sub and box being a slim mount in a tight sealed box muffles and suds bad on the lows. The meds are ok and the highs are about to same as the kicker comp. Nothing too impressive though. Some songs can get my mirrors shaking a little but mostly this box functions as a easy to place subwoofer to add a lttle bass to my music. Iv had two 15 kicker cvr's and later a single12 jl audio w7 before when i had my crown vic so i know the difference between haveing bass that is making your rear view mirror fall in your lap and having something to fit in a limited amount of space to make whats on the radio sound a little better. Im pleased with this sub and box because i knew what to expect when i ordered it and it fit the bill nicely for what i paid for it. ...and..the smell. Lol for the first month of having it id get in my truck to the smell of a new sub box. If youv ever smelled it before you know what im talking about.

The following review is for R2S-1X12, which is a part of the bundle you are viewing.

It was a good sub, especially for the space. But it has limitations, the voice coil and cone degraded with age.
