Great.

Very Sleek, Pretty Powerful. For the price. DEF. worth it! The end caps are a little annoying when tinkering with it at first. I almost left them off. This is paired with two Boss Outcast 12's and it's super Loud. and the amp only stays halfway up. I would recommend this to anyone looking for a powerful budget amp. But if you just wanna Blow money and get super power, Go with Kicker, Orion, JL, or Rockford.

Not too bad

I have had this amp for just under a year , i am pushing a 1200 rms sub @ 4ohms, recently reconfigured to 2ohms , it played for about a month the suddenly one morning no sound from the sub . The power light was on , protect light off , but no sound. Thank god for sonicelectronic great customer service , they had a rma ready for me by the next day .

Overall the amp is great, it sounds good, i pushed it alot @4ohms, but i think the combination of the 100deg+ summer heat and the extra load @2ohms broke it.

great

This amp is great I have it powering two Pioneer subs , seen the same one in store for almost 3 times as much. I would recommend it to anyone

Joke

This amp is a joke. Good if you only have one sub but for price you pay I expected it to push both my subs since it has more power then one. On a side note it does make my one sub I can hook up to it hit hard so if you only plan on using one sub then this amp will work fine.

i got one lol

I bought this last week. It arrived today and I must say im a little pissed i have an spl1000 watt amp and its almost twice as strong as this plus my 2000 watt boss amp was stronger too. it dosent get hot my spl does but it bangs way harder. So if u have 1000 maxxx sub go for it, anything over that and you'll prolly be dissapointed like me. lol
