Review: 10 years still strong - I have now owned this sub amp combo for 10 years. When I first hooked it up, I had a seperate amp not realizing it came with one. How could it be this cheap and have its own amp? I hooked it up to a 2f capacitor (I recommend at least 4, 8 is better) to ensure clean power delivery.. and it knocked my socks off. This is not a competition sub. But for music lovers that want clean bass and decent thump that won’t rattle your windows out, THIS thing delivers!! Highly recommended, still going strong after 10 years… I only have had to replace my capacitor due to it being underpowered and hard on my alternator.
Review: Ive been pushing it for about 3 months now and its reached its break inpoint and sounds awesome. Its not super "rumbly" - When dialed in, this thing is absolutely unbeatable for the money. Ive been pushing it for about 3 months now and its reached its break inpoint and sounds awesome. Its not super "rumbly", but the kick drums hit hard, and the bass is very defined and distinguished. When properly wired, and when the gains and crossover are set well on your system, this thing will deliver!! I have pushed it very hard, to the point where my aftermarket main speakers where distorting, and have yet to have any clipping or distortion!! Id definately vouch for the 300w continuos and 500w peak claims!!! Build quality was great out of the box and very professional, Im amazed at the quality of the build, even if the materials aren't supposed to be "top notch" they still look and feel like it!! I can tell definate differences when playing highest bitrate music (320kbps), and would suggest using highest quality music. Overall, a ridiculous good deal so far!

### ⭐⭐⭐⭐ great sub, worth the money
*by P***L on October 21, 2014*

This sub performs the way it says it does. I noticed that when I drove for a while the sun would randomly turn off or stop playing music and I thought I was having the over heating problem....but I just had to ground the sub a little better because I had it grounded to painted surface. Try that before sending it back of trying to cut vents into it. It works fine now and I put it in my 91 4Runner and it hits so hard. Definitely recomend, 4 out of 5 stars just because it's not for competition.
