this i wanted to clarify and some monoblock (Rockford) says bridgeable
how come ??

yes 300/2 = 150.
you cant bridge a mono amp. must be a typo.

two sub irrespective of brands and feed them with same amount of power then what difference can we expect in terms of SPL.
i know SQ would differ but what about SPL.

usually DVC subs are speced with both coils i parallel so yes each coil would take half the power.

you take 2 different subs and feed them the same power, the output will depends on their specs. their sensitivity. their Fs, Vas, Qts, Bl, Mms, Cms, etc...

the 60.4 is a marginal amp when it is used for driving a sub. it is much happier driving 6" speakers. for about the same money as a 60.4 you can get the Pio D510 monoblock which will do a better job with as sub.

D510 available for 9k or so. Check at Bansal for more.

Since the minimum speaker impedance for bridged operation is 4 ohms in GTO75.4, if you have already zeroed on this amplifier, Use a single voice coil of your DVC and leave the other voice coil unconnected. So you got exactly 4 ohms now.

You will end up blowing the sub this way.
