for the normal person, with a standard cab old truck. why the ned of 2 subs.
wouldn't one sub either run in mono or a dual coil sub run in 2 channel.
be more than enough and alow more air room (cubic feet) to allow the sub to get lower in the range and be tighter with a sealed box..
I had a home made box in my 97 f150 with (2)jl 12" (very costly, but still their mid range sub)
and it was overkill.. yes it sounded killer but the sub amp gain was almost off, as it over powered the rest of the sound, and it wasn't a lack of power to the mids and highs (rockfordfosgate 4 channel 100w per with the speakers bi amped, / and a 50w rockford 2 channel for the doors)
sub was powered by a rockford monoblock 500w into 4ohm
