Default Almost no sound

Hello there

I have recently built a stereo for use at a festival. It's 12V driven by the Pioneer GM-D8604(GM-D8604 - Class FD 4-Channel Bridgeable Amplifier | Pioneer Electronics USA). The problem is however, that my hornloaded woofer(Fane International Ltd Loud Speakers) is almost silent. I would assume that as the amp can deliver 300W RMS(4 ohms) the woofer(8 ohms) would recieve about 150W RMS. Shouldn't that be enough to at least make quite a bit of sound? I am considering buying a mono-block amp beside the Pioneer just to power the sub. What do you think?

Maybe you should find out what you connected wrong or what settings you did wrong before buying more stuff

I'm assuming from reading the specs ,you are using the amp in Bridge mode .
You must have miss wired the speaker output or something .
Give it a try in normal ( non bridged mode on one channel) and see if it gives any output and if it does , have a look at the user manual how to connect your speaker and input in bridge mode .
Make sure your power supply can handle 33 Amps !

Cheers ,

Rens
