SoundQubed HDC3.118 18 inch Dual 1 ohm Subwoofer 1500W RMS

I have two in a 12.5 cf box. these are by far the most powerful subs I have even heard. on is 6 months being fed a steady 1800 watts rms and the other is 1 week old and getting broke in at 600 rms. I can open my hatch with these just by the vibration, my rearview is useless. you will not regret these! soundqubed for life.

Does more than rated RMS by ease. Triple stacked 9 inch motors..a lot of sub for the money. Only thing I do not like is the misaligned uneven motor slugs with nasty glue all over them along with huge gashes and chips out of the sides. I hate magnet covers and wanted to invert this...not happening. On the other hand I'm picky, it may not bother you

Smashing lows, excellent mid and high bass. Two subs will hurt your ears.

I gave 2 stars because they are nice looking subs and tthey do pound hard. But I bought 2 and I did a proper breakin time and within 2 hrs after breaking them in 1 of them started make a loud chattering sound like the coil was bottoming out or scrapping. I am gunna recone with a spi recone with huge surround xtra spiders and better coils to both. I was told they were underrated subs but they aren't. Dont over power them.

If you like your truck dont power these too much.. they tend to find the auto makers weak weld points..

Good quality for the price. System needed an upgrade. Decided on this product for the price and qualifications it needed with the amp.

no sticker in my package . Im not very happy with this company , most of the time when your spending good money on a product , they give you a sticker so you can rep. the product, well no sticker for me .

Great subwoofer for the money its louder than any single sub I have heard
