## Questions & Answers

**Q: Mounting depth?**
A: I bought just one but there may be a combo package you can purchase.

**Q: will the 8" version fit a 2002 nissan frontier with the rockford fosgate system?**
A: I'm not sure. I would think so if your Nissan is set up for a 8 " woofer.

**Q: Does it come in a pair or just one?**
A: I bought just one but there may be a combo package you can buy.

**Q: can these handle more then rated rms like sundown underrates their subs?**
A: I really can’t say I returned them and got the svr 8. 
I have 4 of them behind the seat in a crew cab f250 so the box is small and space is limited but they BEAT HARD for the situation they been put in. I have them on a 3000 sundown sfb, but it’s not turned up all the way.

### ⭐⭐⭐⭐⭐ IT HEATS HARD.

Skar audio subwoofer is the best budget subwoofer available in the market. Amazing sound quality. It really heats hard.

### ⭐⭐⭐⭐⭐ More punchy than expected
*by V***N on 22 February 2024*

So initially i had 2 kickers comp r 8 inch under the seat of chevy crew cab, not happy with them from day one, not much low end bass and everytime i push them above 300w they start smelling like burning in just few min, well im soo happy now with these Skar, no joke, such a difference, i didnt expected. I can feel that bass and i can really push the amp now to the limits at around 700 watts. Im replacing also the amp with Skar. I cannot believe for the price and its not super branded like Kicker. I think in the future i will stick with Skar and probably upgrade later to the EVL series as i heard great stuff about them. Hope they will last.
