  1. Just buy it. Really decent Lil amp powers a Kicker CVR-15 just right. Pairs nicely with the 300/4.05/29/16 Update. Still going strong after a year of powering the CVR-15, Slightly disappointed with having to say it’s a 500 watter. Any other old timers like me this is equal to the punch 75, autotek 90mxi or hifonics thor which all were only rated for less than 100 watts but could out power this new school stuff.04/17/17 Update Year 2 of still going strong with no hint of ever…

  2. GROUND POUNDER This’s a monster!!Mine birthed at 643 watts. So 143 watts over. Be careful with this little beast, make sure your subs can handle this as its a CEA-2006 compliant amplifier, meaning its true power..I have it running two kicker compr 12 inch subs, and it push’s them without breaking a sweatThis amp reminds me of the 80s and my first punch150 small foot print ALOT of power, But in the 80s the cost was about a dollar a watt, so this’s a true value.. Glad to see Fosgate is back to what it…

  3. Strong amp and great sound I had a cheap Pyle amp for probably 4 years and it didn’t give my subwoofer the sound it needed but I never knew it until I got this one. That amp blew up (so cheap I’m surprised it lastest this long) so I decided to get a brand that I could trust.This amp is a little beast to say the least. I like the variable bass control that comes with it as I listen to different kinds of music. It pairs with my Fosgate P3 perfectly.If you’re in the market for a nice amp don’t even hesitate to…
