Ok so i found the subs i want, i plan on getting 2.
heres a link if you wanna see too
but i picked these cause they just fit (top mount depth wise) in the the sub box i plan on getting for my truck. I know you not really to look at the watts its uses but rather the rms which is 700 for these. And its a dual coil 4 ohm sub. I tried to do some research but its confusing. I understand that dual coil 4 ohm can be wired together to make it 2 ohm, but the confusing parts comes when trying to pick an amp.
I saw this one and thought maybe it was good
This one sars it has 1750 rms (which i read is sometimes better just to be slightly higher in rms than your subs so you dont over work you amp)
but im confused, do i need an amp that pushes 700 rms or 1400 rms? Im confused when reading the specs of an amp and it says something like
this is for the amp there
Max power 2 ohm 2500W x 1
RMS power 4 ohm1000W x 1
but then i would see this on another one

Max Power @ 1 Ohm: 2600W x 1
Max Power @ 2 Ohm: 1800W x 1
RMS Power @ 2 Ohm: 1200W x 1
Max Power @ 4 Ohm: 1400W x 1
RMS Power @ 4 Ohm: 750W x 1

It just confuses me, can anyone help me out here?
