What's the resistance of my HAES 4X40?

[gandrade1]

Hello all,

I am in the process of choosing the right components to update the audio system in my 2001 Porsche Boxster. So far, I have replaced the dash and the door speakers. When I replaced the dash speakers with Infiniti Kappa 42.7 i (specs below) I noticed a great improvement, however the replacement of the door speakers (with 5 1/4 focals 130 CA) did not benefit much the bass of my car. I further noticed that the dash speakers are 2 ohm while the doors are 4 ohm. Can that have any impact on the results I am getting now? Should I have replaced the door speakers with 2ohm’s coaxials based on the current amp I have HAES (4X40w non DSP). I don’t have the specs for it…

The other question I have is what amp should I chose (or what specs should I look) as I chose the replacement for my current HAES, based on the speakers I replaced (specs) below?

Thank you very much for your great support (I love this space)

Gustavo
