I am new to the forum but not to audio world. I have a 94 Toyota Pickup with an Ext Cab. I want good quality sound not something over powering. I should be looking at a 8in or a 10in sub? Thanks in advance.
A single 10 with a few hundred watts will blend in well with your front speakers and still have the ability to overpower them if in the right box. I have a single 10 in a 28hz box and barely even get that thing moving when listening to music.
Not to mention with the same model subs, just different sizes, 99% of the time you'll be able to extend lower with the 10" version in the proper box(I dare to say 100%). There's really no reason to choose the 8" over the 10" unless it's purely for space reasons or you feel like being different.
