re audio rfx8d4
I have two of these ported in a mazda miata and damn do they sound good. They hit low and get very loud. They are only getting 350 watts for both and they just sound super clean. I would recommend to anyone looking for cheap good quality subs. The terminals are the only bad thing.

RE has Awesome Quality
I had bought this sub for my home entertainment center and built a box that integrated it into my entertainment center and is about 1.5cuft and tuned to 32hz and is very clean and hits really hard for an 8 when i had some friends over they thought i was hiding a 12 somewhere which goes to show if u have the right box anything can sound great, the sub itself is constructed really well all except the terminals, they are old school spaded terminals that are easy to bend, over all best 8 for the price

Exceptional 8's!
These are fantastic little monsters. Pictures don't do justice to the motor on these puppys. Great X max and lots of motor force. @ in a 1.5 Cube box with a side slot port tuned to 30Hz in the back of a jeep off of a crunch 800 rms amp puts a smile on my friends face.

Awesome!!!
I have a 2010 nissan frontier crew cab and was very limited on space under the back seat. I wanted a clean hard hitting system but not spend a fortune and really liked the price of the RE Audio subs. I talked with a tech at RE Audio and told him the space I had to work with and he suggested these ported. I've never had 8's and the hit hard and deep! It's very clean as well! I'm running 2 at 4 ohms and giving them 220 watts per sub and its awesome! I would highly recommend these to anyone! They are very well built other than the cheap speaker terminals but that's the only complaint.
