Will this amp work with my 8 ohm subs?

I have 2 10in subs at 150 watt rms each. These subs are 8 Ohm. Because the subs are 8 ohm I believe I need twice the rms wattage. I believe that I need to get an amp that has 600 watt rms at 4 ohms. These are the specifications of he amp I plan to get:





Sony GTR Series 1-Channel Class D Car Amplifier


RMS Power Rating:


4 ohms: 600 watts x 1 chan.


2 ohms: 900 watts x 1 chan.


Max power output: 1300 watts x 1 chan.


MOSFET power supply


Active thermal control


Single channel operation


Speaker-level inputs


Preamp RCA outputs


Dynamic distortion suppressor indicator


Heavy duty aluminum alloy heatsink for extreme heat dissipation


Gold-plated RCA level inputs


Gold-plated screw terminals


Variable low-pass filter (50-300 Hz)


CEA-2006 compliant amplifier


Frequency response: 5-300 Hz


Dimensions: 10-7/8"L x 15-7/8"W x 2-1/4"H


4-gauge power and ground wiring is required for installation.


1-year Sonic Electronix warranty





Will it be a good match?|||If they are single voice coil... then that amp will over power them.





Heres what u need if they are single voice coil





300x1 @ 4 ohms





If they are dual voice coil:


300x1 @ 2 ohms, or 150x2 @ 4 ohms.





Sony makes crappy amps btw...





EDIT: He meant twice the RMS wattage at 4 ohms. Example, if its a 2 channel amplifier, and they are single voice coil, its safe to assume an amp that does 300x2 @ 4 ohms will provide 150x2 @ 8 ohms.|||no, those subs are rated at 150 rms watts, if you wire them in series/parrallel you will get a 4 ohm load which will receive 600rms watts


when you wire those 2 8 ohm subs you will get a 4 ohm load... you will be overpowering them by double their rms ratings which will eventually cause them to blow, you want an amp that puts out 300 rms watts @ 4ohms.

edit:





by the way, your wrong about "Because the subs are 8 ohm I believe I need twice the rms wattage." thats not true, 8 ohms is less resistant than 4 ohms would be, therefor you would need half the rms wattage and not TWICE the rms wattage
