PSI 1] Pressure ] volts

GPM 2] Rate of Flow ] amperes

Size of pipe 3] Resistance ] ohms

If you throw a glass of water on something or if you throw a gallon of water on something or if you dump a30 gallon garbage can of wateron something [< this is what we want <]

for a big "H I T" of sub bass , we need to increase current in amperes by decreasing resistance in 0hms [ i.e. maximum current / minimum resistance ]

Dual Voice coils can either be run in series or parallel [ parallel lowers resistance ]

A high current amplifier is desirable [ maximum flow rate with minimum resistance to flow ]

i.e. A dual 1 ohm driver can be wired @ 0.5 ohms [ one half ohm final impedance/resistance ]

If the amplifier you have is " 1 ohm stable " versus say: makes it's power/watts into 4 0hms or 2 0hm stable it may handle more current.
