  • Blew
Size: 12" - Dual 4 Ohm
Its a good sub but it didn't last long. Coils burned and now my entire car smells like something burnt. Refund was easy and I just used it to buy another one since I liked the sub. Hopefully next one will be better.

  • Quality Without The Price
Size: 12" - Dual 4 Ohm
Sundown makes a great sub. The LCS is their entry sub. I've got one for my 4runner and my Wife's 4runner. They sound phenomenal. Each of us is only running 300 watts, but that's enough for us. We have each one in a Skar Audio AR1X12V box.

Awesome entry level subwoofer!!! My first sundown subwoofer. Sounds Awesome! Recommended for small ported box, but I have it in a 1.5 cubic foot sealed box. Sounds amazing and still breaking it in! I will not hesitate to purchase another sundown audio subwoofer!
