Looking For the right AMP
 

I just got an Infinity Sub (KAPPA PERFECT10VQ)
Power Handling, Peak: 1600 Watts
Power Handling, RMS: 400 Watts
Sensitivity: 87dB
Frequency Response (±3dB): 25Hz - 400Hz
Mounting Depth: 6-1/2"
Impedance: 4 Ohms

And i was planning on getting an Alpine AMP (MRP-M650 Class-D Mono Power Amplifier)
# CEA-2006 Power Rating (40hm@14.4V = 1%THD+N), S/N 65dBA (Ref. 1W into 4Ohm): 400W x 1
# RMS Power (at 14.4V THD+N, 20Hz-20kHz):

* Per channel into 4 ohms: 400W x 1 (0.08% THD)
* Per channel into 2 ohms: 600W x 1
* Bridged 4 ohms: 1000W x 1 (0.3% THD)

# Bass Engine Sound Tuning:

* Crossover Frequency : 50Hz - 400Hz LP (-12dB/oct)
* Subsonic Filter (Fixed): 15Hz
* Bass EQ Frequency (Fixed): 50Hz +12dB

# Frequency Response: 20Hz - 200Hz (+3,-3dB)
# Signal to Noise (S/N): 90dBA (Reference to Rated Power)
# Input Sensitivity (For Rated Power): 0.2V to 4.0V (1.0 at Center Detent)
# Input Impedance: 10k Ohm
# Speaker Impedance: 4 or 2 ohm Bridged

I was wondering for any other suggestions

I highly recommend MTX amps. Their manufacturing process for car amps is much better than most. (although you can't go wrong with a Nakamichi, for the extra dough).

Although I appreciate the specs you gave in your post immensely, you left out a crucial bit of info - How much are you willing to spend, and what do you wanna get out of it? Are you willing to spend arc or zapco money? JL Audio 500/1?? You wanna stay more reasonable in price, like

??

JL, kicker, phoenix gold, RE audio, Earthquake. Nothing else :)

Nothing? Not even Tru, Arc, Zapco or Mac?:D

Zapco is like a forum favorite on elitecaraudio and canadiancaraudio.

I really wanna spend around 300

the best amp company is US AMPS i got my directly from a dealer so i paid less i thi nk they run about 600 but are welll worth it.

Generally you will get what you pay for with amps. If you get a high proced amp to put with your Infinity sub (like JL, alpine, infinity, etc.) you will really love the clarity you have. And having such a nice sub helps too
