Hi guys. I have just a little knowledge on speakers impedance, so I am asking for help.
I have a Suzuki Grand Vitara. It comes with this active subwoofer, wired in parallel to the rear door speakers.
The SW label says this:
TORISAN FSP-SW101.
Max ouyput 80w
Rated output power: 40w
DC: 14.4V Negative Ground
It was not working, so I decided to open it. The speaker itself was damaged.
It's a 3.5", dual coil (2 ohms per coil).
(This friend of mine just told me 3.5" and subwoofer should not be used on the same sentence. I agree)
Well I took it to the "speaker repair shop" and I got it back today.
I tested the speaker and it produces sound on both coils. However, I measured resistance between the terminals and it shows 8.1 ohms on one side, and 9.2 ohms on the other.
I'd like to know what effect should I expect from the impedance change I described, both on possible damage to the equipment, and sound quality.
As a side note, I installed the subwoofer and the sound is quite poor.
Thanks in advance.
