  • It’s a hit or miss
The media could not be loaded. Sometimes you get good ones sometimes you get bad ones if you look at the video it’s supposed to be 4 ohms and it says 3ohms

  • Handles more than 600w rms
So I originally bought the sub and box combo. Comes with a DVC 2ohm 18 and box. I purchased a this DVC 4ohm to wire down to 2ohm to use on my 5 channel amp that's stable at 2 ohm 600w rms. Decided to put the 2ohm in the the box on my Pioneer GM-D9701 which is 1ohm stable @ 1,200w rms. The SDR 18 handles 1,200 with no problem considering its rated at 600w rms. ... show more

  • They're worth the money
I used 2 sdr-18's for my infant baffle build in my saturn ion redline. Love how they look and perform. Arrived on time with no damage. Only problem I have is that I dident get a sticker with one of thelm. You would figure paying 130+ for a sub they would make sure the sticker was in there. Overall a great experience. I would buy again. ... show more

  • Definitely worth the money
The media could not be loaded. Definitely worth the money and perfect for a daily ride they exceeded my expectation for the price, I put two in a 99 explorer with a ssl 3000 watt amp (@2ohm) I have my bass knob halfway and my shirt dances standing outside of the vehicle I didn't have to do the big 3 upgrade higher output alt extra power cell..... nothing so I highly recommend for daily rides or bass heads on a budget ... show more

  • Value for a 18!!
Just got it and I'm playing only on 150 watts for now in a 8 cu ft ported box with a 6 round port and WOWOW for 150 watts and not broken in yet man it hits thundering lows. Will keep updated after I get a 600 rms to see how it handles it.

  • Definately worth it
Built with great quality components for a amazing look. The huge rubber surround looks amazing with a basic shield only displaying their single color logo it fits well into any vehicle. Produces amazing bass response even at lower volumes . It will not disappoint if you are looking for something to make your teeth rattle. Paired perfect with a 500rms amp for exactly the sound I was hoping for. Word of advice. But the package with the Skar branded ported box I regret starting out with a sealed I built to specs. The kit version got sounds and looks amazing in the back of my SUV that said fe this will NOT fit in a car. ... show more
