It's Friday the 13th for the month of May. It's been exactly 5 months since I have owned and used this subwoofer. I never would have thought I would trust a brand I never used to satisfy the quality and strength of my intentions. I'm using this in my room with a car amplifier powered by an AC to DC converter (given only powers about 600rms) with my shelf Sony system. The lows fulfill a love to audiophiles who love the lowest bass that almost goes out of your hearing range. For the price Sonic Electronix gives, why would you go into any other audio shop? These hit amazing clean and knocks picture frames off the inside of the house if the volume is just right. If you have to make a decision, go sealed. Excursion looks like a paint mixer for those who are curious for that kind of ability. I would recommend this to everyone looking for a subwoofer that can cause sickness to your stomach.

I bought this sub and had it running in literally a (badly) sealed old bass amp box for a while and it still knocked pretty good. I now have it in a custom box for my Civic, feeding it all of 1500w RMS and it outlasted the amp! I plan on getting at least another 1500w amp to power this thing. I would get another if I had the space. Had a JL 13W7-D1.5 before this, and I think this one is louder. Sure it's a 15" and being given an extra 500w, but for $100 sub this thing is crazy.

I had an SPL sub in the past and it made my head hurt every time it hit. Till I got jacked! It works very well with my Rockford class D 1500 just like the last one I had. It rocks believe me (hooked up right) I got hearing loss to prove it!

Wuz up guys all I have to say is this sub hits really hard. I have one 15 SPL SP3 and it is power by a 2000 watt spl class D amp and note that I have it running of my factory car stereo so I can't wait until I get my flip out or a in dash to see what it really can do. and also I did not even tweak my amp ether so for my first system this is a really good system and for the price I would recommend this sub for a person that like they car flexing.
