you dont state enough info here for use to help you... first off what model amp is this rockford makes quite a few amps... and what 2 subs are these? model number please... audiobahn makes at least 10 differnt subs that handle around 500watts.... once you supply this info we well give you a game plan for wiring these guys up.

i'm assuming you mean AWC12T anyway

well first off you are grossly under powering these subs they are 500watts RMSn each and you are only giving them 300watts RMS this kind of gross under powerig very likly well cause damage in the long run. i do not suggest running these subs with only 150watts to each one.

these subs are also dual 4 ohm voice coils which means you are going to only be able to wire them as a pair to a 4 ohm load or a 1 ohm load. the amp you have needs a 2 ohm load to get the most power from it. there is not a way to get this sub and amp combo to work properly. at 4 ohms these subs well only get 75watts each this is going to cuase them damage as they well most likly clip badly. these subs really need a minimum of a 800watt rms amp to perform properly and if that amp is mono it well need to be 1 ohm stable....

if you have any questions please ask if you like we can help you fnd a more apropriate amp for these high power handling subs... also you could use just one of the subs and that would work alright with this amp...

Agreed... this amp is much too small for both subs. It will do OK running only 1 sub at ~300 RMS @ 2 ohms. Also, this is a Class A/B sub amp. It really sucks power for the amount of watts it will produce in music power. A Class D or T Mono amp... (1 ohm stable) with about 1000 watts RMS will do the job well here. Yes, this amp will pull 2x the current from your vehicle electricals. But the amp will definitely deliver more that what you have now.

As Chronos mentioned, there is no way to wire both subs for this amp, to get the optimal power output from same. Best you can do is wire the subs for a net 4 ohm load and suffer with ~75 watts RMS/sub. You'll get more output from a single sub, wired for 2 ohms (parallel) with this amp. About 300 RMS this way... to a single sub.

Try just one sub for a while if your enclosure is sealed/ported but each sub has its' own airspace chamber. If that is not enough bass, new amp time.
