Amp for Type R Subs
I currently have some 2 low end 12" kickers powered by a DhD PowerCruiser NXT-3104 which according to the web site is:
Max. Power 800w
2 Channels
Total Power @ 2 ohms 100w
Total Power @ 4 ohms 75w
Total Power Bridged 400w
The amp actually says its 1200watts on it so maybe they changed the model into weaker powered amp, but anyways I plan on selling my kickers for one Alpine Type R Sub. My question is my amp ok for this sub, and if so should i purchase the DVC or single 4ohm version of this sub.

Also need to know if the amp is stable at 2 ohms when bridged, most 2CH amps are not.
If the amp is a 2x75watts into 4 ohms then it should be 1x150watts into 4 ohms and that is not enough for a type R that is 500 watts rms and 1500 watts peak

Re: Amp for Type R Subs (fcm)
i bought the amp cheap and used so i dont have any spec sheets for it. The amp says on it that its a 3104 series with 1200 watts, the dhd websites lists the 3104 as a 800 watt model. I did however find some specs for a 1000 watt 3104 series amp:
Number of Channels 2
RMS Power (4 ohms) 150 watts x 2 chan.
RMS Power (2 ohms) 200 watts x 2 chan.
RMS Power (1 ohm) Not Stable
Bridged RMS Power 400 watts
Peak Power Output 1000 watts
Min. Impedance Unbridged 2 ohms
Min. Impedance Bridged 4 ohms
THD @ Rated RMS Power 0.03% (4 ohms), 0.08% (2 ohms)
Speaker Level Inputs No
Amp Preamp Outputs Yes
Built-in Crossover HP (50Hz-1kHz), LP (35-500Hz), Subsonic (27Hz Fixed)
Bass Boost 0-18 dB
Signal-to-Noise Ratio >95dB
Hopefully this helps, if the amp is still no good do you have any recommendations on an amp that can push this sub?

</TD></TR></TABLE> Just from the specs alone its a better amp , it's also a monoblock, and stable down to 1 ohm, all good, as for how good the amp itself is, I don't know 94
