  • Punches above it class but you must break the sub in
Size: 12" - Dual 4 Ohm
For being a budget sub it punches above its weight for sure it needs to break in to reach that 500w rms so play it at half volume for a few days or the voice coil might get hot at first I thought it wasn't good but after letting it break in man I’m sending 500w rms and sometimes more to it no problem and it bumps deep bass that you can feel in your chest shaking my whole trunk there’s not a lot of subs in this price range that can do this very impressed by this 12 inch sundown for the money ... show more

  • 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!
