While it may /work/, you're going to be operating outside the specified parameters of that amp (warranty void). You're also going to be sending way more power than the sub was built to handle. Before anyone chimes in with "set the gain all the way down" -- that's not the correct way to solve this problem. It's still a 2 ohm load, and the amp is likely to overheat and, depending on how you install it and how hard you drive the system, you may cause permanent damage to the amp and/or sub.
For basically the same money, I really think this is a better/safer choice:

...or another amp of similar RMS power, rated stable for 2 ohm mono operation. It will be a much more appropriate match for the sub's specifications. If you're worried that it won't be enough power -- it will. Trust me. If you set your gain correctly, you can get 400W RMS+ out of it without clipping or distortion, which is EXACTLY perfect for that sub.
A class D amp will also run a lot cooler and typically be quite a bit smaller (physically) for equivalent power output, making installation a WHOLE lot easier too. |
Yeah I already figured out I got the wrong amp. Luckily Crutchfield has a good return policy, so I'm just going to buy an amp from the place that's doing the install. Also getting door speakers from them.
I got in a hurry because I decided I wanted to get this done by Saturday for the twisted sisters group drive here in SA, so I just picked one so I could get the order in. I'll stick with my head unit and sub, have them provide the amp and door speakers, do the install, and remove the rear speakers as I hear they are useless anyway.
They said they'd do the install for 100 bucks, and they got really good yelp reviews. My roomate also bought his system from them and had them install it, he was happy with them.
I'll report back on Friday and let you know what happens and how it turns out.
