Hello,

I've got a question concerning wiring a mono-channel amplifier and a subwoofer (DVC). I read through the wiring tutorial at 12Volt and it seemes clear, but there still occurs one 'problem':

Is it better to wire it:

a) parallel: amplifier @ 2 Ohms, subwoofer @ 4 Ohms

b) series: amplifier @ 4 Ohms, subwoofer @ 2 Ohms

any changes on power, safety between these two solutions?

Thanks

Kiddo

The wiring of the speaker changes the output of the amp, not the other way around. A amp cannot be 2 ohm while the sub is 4 ohm for example. The amp is what the speaker tells it to be. Meaning a dvc 4 ohm sub wired in series will be a 8 ohm load to the amp. The same sub wired in parallel will be a 2 ohm load on the amp. Always post the brand and model# of the equipment you have or will be buying.

Oh sorry, forgot about that.

The amplifier is an Alpine MRD-M301 150W RMS @ 4 ohm, 250W RMS @ 2 Ohm

Subwoofer is a Pioneer TS-W306, if I'm not mistaken, 400W RMS (2 - 6/8 Ohm)

Well, the tutorial just shows some different numbers, if i compare amp and sub Ohm. But okay, since you guys say so, I'll be fine. So which of this solutions would be better for this little system?
