[QUOTE="audioholic, post: 7523425, member: 549629"] Output signal voltage over 2-3 volts is a waste. If you have an induced noise problem that is still audible over 2-3 volts of signal strength, then you have a large enough noise problem that it needs to be addressed directly (and should be easy to locate/correct), not just try to mask more of it by getting a hotter signal. So dont lose any sleep over an 8v output versus a 9v output. Your ears will never detect THD differences between .05% and .005%, dont even give that spec difference a second thought. Yes, you will need RCA cables. Also, you will need external amplifiers, since the built-in amplifier in the h/u will not be affected by an outboard EQ. The advantages of a 12" sub over a 10" sub is more cone area, for greater air displacement potential. This may seem like a vague answer, but any other more specific answer, like lower fs, is a generalized statement that will not be true in all situations. Class a/b amplifiers usually have maximum output at 4ohms (mono), while most class d amplifiers generally have peak output at 1ohm (mono). So yes, a dual 2ohm sub has the advantage of being able to wire to either 4ohms or 1ohm (mono). If you are only getting 12.1-12.6 volts to your amplifier(s) while the engine is running, you have a severe resistance problem in the power supply circuit to that amplifier, and it should be addressed immediately.
