Ok now...getting back to ur question, Alpine amps are ok. But if what you want is brand matching, stick with alpine and find a better amp model. Here's one that might interest you but it just costs more:
MRD-M500
RMS Power (at 12V,20Hz-200Hz)
Per channel into 2 ohms : 400W x 1
Per channel into 4 ohms : 200W x 1
RMS Power (at 14.4V,20Hz-200Hz)
Per channel into 2 ohms : 500W x 1
Per channel into 4 ohms : 250W x 1
Not a bad amp. Along with the amp, maybe get:
SWR-1241D
Power Handling Capacity (RMS) : 300W
Impedance (Nominal) : 4 ohm + 4 ohm
From the look of things, this setup will run you about $700-1000. Depending on where you go. But it'll bump!
