I need it to power one of these:

MBQuart DWE254 10in Sub

* Impedance: 2x4 Ohms
* Frequency Response: 25 – 300
* Sensitivity: 2,4 dB
* Power Range: 250 watts
* Crossover Freq: - Hz
* Crossover Slope: - dB/octave


overkill? too much power?

the only reason I ask is because I can get that amp for $240 to my door. It's the best bang for the buck. I found last year's Alpine at around 200W for $200. :eh:

 

That thing is going to be putting out 600 watts to a sub that is rated for 250 watts. More power is always good, but then there is just too much. h: But I think if you keep the gains down, you will be fine.

 

y dont you just get a more powerfull sub

 

I found the this one really really cheap, so I picked it up. A single 12 is in the future plans, but not for a while.

 

check out alpine type s subs, they not too expensive and i think have a power rating of 900 watts

 

It's better to get low rms subs with high output, aka mtx thunder 4500.

 

i would just put the sub in a sealed box for sure and you otta be ok. More power more better!
