Speaker sizes

[Mofoka]

So I have a 2001 SE w/ PP.
I checked out cardomain.com and they said that the 2001 Sentra has 6.5" in the rear and 7" in the front. However, I don't think they factored in the PPif it makes a difference in speaker sizes.
Main question is, what sizes are the speakers in the front and the rear for a 2001 SE w/ PP?

Read the two stickies at the top of the Audio section. It has all the information about the audio system that you'll ever need. Basically, though, CarDomain is wrong, the speakers are 6.75".

6.5-6.75 all around

Front are 2" deep but you can fit up to a .75" one piece spacer or 1" two piece spacer, giving yourself 2.75 or 3" depth respectively. The rear has around 2.25-2.5" depth before you hit the torsion bars.

I want to buy Infinity KAPPA speakers and they're 7" fronts and 6.5" rears. Here are the specs:

Fronts (Infinity KAPPA-652.7I)

Power Handling, RMS: 75 Watts
Power Handling, Peak: 225 Watts
Sensitivity: 94dB
Frequency Response: 45Hz - 25kz
Mounting Depth: 2-3/16"
Impedance: 2 Ohms

Rears (Infinity KAPPA 63.7I)

Power Handling, RMS: 75 Watts
Power Handling, Peak: 225 Watts
Sensitivity: 95dB
Frequency Response: 45Hz - 25kHz
Mounting Depth: 2-3/16"
Impedance: 2 Ohms

LMK if these will fit or if I'll need adapters/spacers, or anything else.

They will fit, but the kappas don't sound very good and you'll also need an external amp to run them since the headunit can't handle 2ohm.
