Following up on my earlier post, my car kit has an issue; the speaker in the Garmin sounds like crap and is too low (I think the car kit has the amplification, but the speaker is distorting the sounds). So, tomorrow it is back to Fry’s to look for an external CB (marine) speaker that I can mount under my center console. I also wired the car kit using only the front left speaker, so maybe if I wire all speakers together, I can get decent amplification with a decent speaker (there is probably a flaw in this theory, something to do with impedance I’d guess).
