Disappointed...

The following review is for R2SD2-12, which is a part of the bundle you are viewing.

I had 2 of these hooked up to a rockford fosgate p300 running at rms power and within a few hours, both subs were out of commision. the voice coil went out on one, and the other simply quit playing mid song. I was only listening to them at about half volume of my head unit. but for the time that it did work it sounded excellent. i just expected so much more from rockford fosgate.

The following review is for R2SD2-12, which is a part of the bundle you are viewing.

Works great for the application wired the coils in series for the bridged output on my amp and the whole truck shakes, sounds crisp too

good truck sub

The following review is for R2SD2-12, which is a part of the bundle you are viewing.

I installed 2 of these in a 99 chevy 2500 4 door they sound good for such a small sub. Depending on where and how you mout em ported/sealed depends on how they will sound in my case they added that extra low end fill i needed for great sound quailty.

Louder than expected

The following review is for R2SD2-12, which is a part of the bundle you are viewing.

My first shallow mount sub and I was worried it wouldn’t sound near as good as a standard depth subwoofer. That wasn't the case at all!

Nice Modest Sub!!!

The following review is for R2SD2-12, which is a part of the bundle you are viewing.

Purchased this Sub to put in my 09" Tundra. I've been running 300w @ 4 ohms to it four about a year in a sealed box. Sounds great for an entry level sub. Just remember, GOOD IS RELATIVE TO YOUR APPLICATION!!!!!. If you want bass below 40HZ this may no bet the sub for you. It has difficulty with most modern RAP music because of all of the 30Hz notes. However, this has been a good reliable sub and sounds great depending on the music your listening to and the environment you are putting it in!
