Why did you choose this?
Sonic Electronix Store
Needed a good amplifier and did have a lot of money to spend on one. I did some research and found crunch. And I cant complain about the product its a good amp if you don't have a lot of money to spend. You cant really expect much from a cheap amp but I got more than I expected.

I have a 15" sub its 450 RMS and dual 4 ohm...I can use this amp for it?
A shopper on Oct 16, 2014
Best Answer: Yes, you absolutely can.
I used a 500w rms elemental design 15" sub and it pounds like a bomb! Just make sure you don't increase the gain to much. Plus I love the lights on the amp, it looks great at night. But yeah, this amp is perfect for your sub. But to get the most out of your sub, wire it to 2 ohm and it will work smoothly. Also, the amp never heated up for me, even tho I use it an hour a day, it won't heat when you use a 12 gauge speaker wire. Sorry about the long info but yeah it's perfect for me and it probably will to you too.

I have 2 Hifonics HWX12D4's and I'm needing to know how to wire them properly with this amp?
A shopper on Apr 2, 2015
Best Answer: Hello,

Please be advised, before reading the answer below, this is not a suitable match. The amplifier is Not stable down to 1ohm, so you are obligated to wire the setup to 4ohms (below will show how). However, the amplifier's output is no where near the power that the drivers are asking for. You seek an amplifier doing ~700w RMS @1ohm or @4ohm.
