CT Sounds Bio 2.0 12 Inch Car Subwoofer Dual 4 Ohm

Purchased two of these, they look great and seem well built, one of them sounds great and one of them has a terrible rub in the voice coil. Amazon has refunded the full amount and I will be buying another.

Good

It says 250rms / 500 max no400rsm / 800 maxI just get the sub today and I was happyBut then I seen the rms, it's more then what I want to use but It will work just fine as is. Overall I love sound amazingcan it's big.

I bought this for my husband for his birthday! He absolutist loves it! very sturdy and heavy duty! we built a box for it and if fit perfect beind the seat in our single cab pick up and it sounds amazing you can hear it outside the truck with doors closed over 3 blocks away when it is turned up. We plan on buying 2 more for my SUV!

Hard hitter with low wattage raitng, ordering 3 more to build a budget wall. Specs were made for an 8 inch aub, not the 15. Box I built is 2.41 cubes and should probably be closer to 2 cubes only. Ported of course.

A great sounding bang for the buck. Doesn’t have a whole lot on the low end, but it kicks really well. I recommend using a sealed box for this sub as it will produce better quality, but overall, not a bad sub for a beginning system

Nice bass speaker for a small system with low power requirements. 500 watts amp will push these very well.Follow up: I am pushing these with a JBL 600 watt amp and they are fenomenal. They have huge potential and almost feel like 15s. I cannot not believe i get so much out of these. Great value.

great low power subwoofer with plenty xmax to get those lower frequencies.. I used for my home theater in 2.0 cf box. 4in port tuned to 30hz off a 300 watt plate amplifier.plays lows with authority.. just as good if not better than my $500 home theater subwoofer.and 40$!! great buy great sub from CT sounds!
