Pros: when i was looking for a sub for my car i just wanted something that was cheap and would look good, but i got more than that. i'm running a Sony XR-M550 head unit with a Dual XPA2500 amp and its mounted in a Q-logic bandpass box. for as cheap as it was i am VERY proud to own TWO of these subs. i've now owned theme for almost five years and haven't had ANY problems. :)

Cons: it only sounds great in a ported or bandpass box otherwise it doesnt pay to buy it unless you want it for looks.

Other Thoughts: over all the BEST pair of subs i have ever owned that lasted as long as they are did now with the beating that they get.

Pros: Price
Watts and RMS
Size

Cons: None to speak of really. Read other thoughts for an idea of a con.

Other Thoughts: I'm running this woofer with my head unit ( pioneer avic z110bt) and a TIS 5 channel amp (500 Watts ) when I put the bass all the way up the low frequency hits well but followed by a higher frequency the woofer cracks when pushing ~600 Watts. Over all I'm very happy with the sub and would not hesitate to buy it again. I have upgraded to a pioneer champion pro 3000 Watt peak 800RMS and I'm happy with the performance Of both but the pioneer was 7 times as much.

Pros: it loots sweet. looks really amazing.

Cons: everything else. i had it hooked up to a 400w amp and it blew it in 20 min. no insane bass stuff just some basic bass tests. it honestly sounds like a cruddy speaker. the amp is a quality amp because it works amazingly now with a good poineer sub. DO NOT BUY! it will die if you do anything to it.

Other Thoughts: just noticed, its been sitting in my room as a nice place for me to throw my keys when i walk in. just noticed that the speaker cone has started to separate from the actual frame. if it were hooked up it would just rattle now. and thats just from tossing keys into it! imagine any long term use of this product, then smack urself in the face because its a BAD IDEA!

Pros: ok, i bought this not thinking much of it. it has a very good sound with out the insane vibration

Cons: 600 watt peak paired with a 600 watt amp, need to be finely tuned to sound good

Other Thoughts: bought this to replace a stock sub in a scion, the stock one had to much hollow bass to it so i got this one to get a better sound with out running high gauge wire or the need for a new headunit. it hits good sounds like a 800 watt or high sub but with out the physical "feel".
