i have 2 12" Sony P5's in the back of my hatch and i wanted to know what size 2 channel amp should i run?

Here's the specs

Impedance 4 ohms
Cone Material Polypropylene
Surround Material Foamed Rubber
Sealed Box Volume (cubic feet) 1.15
Ported Box Volume (cubic feet) 0.82
Port diameter (inches) 3
Port length (inches) 12
Free-Air No
Dual Voice Coil No
Sensitivity 89dB
Frequency Response 18 - 2k Hz
RMS Power Range (Watts) 90-380
Peak Power Handling (Watts) 1300
Top Mount Depth (inches) 5 5/16
Bottom Mount Depth (inches) N/A
Cutout Diameter or Length (inches) 11
Vas (liters) 86.7
Fs (Hz) 24.8
Qts 0.37
Xmax (millimeters) 5.7

 

I would use a stereo 200wpc, but read the fine print on the specs! Make sure it's "continuous rms" output, rated at 12 volts into 4 Ohms. Many higher ratings are claimed, but may involve "peak" power, lower impedance, and requiring higher voltage (the last time I checked, an auto and its battery are 12 volts, no higher). An amp that meets these specs should do you just fine. IMO

 

Go to Crutchfield.com.....connect to a live technician on line....they're good with specs...

 

Yeah, they are great for finding out information. There prices are much higher than they should be but I find them very useful when looking stuff up.

 

use a mono amp not a 2 channel youll get better bass and sound out of it since its made for subs
