Base radio/cd output watts?

370z_Roadster · 09-25-2014, 09:23 PM

Considering that the Base head unit uses a BTL amp, your likely to see no more than 20w RMS. My factory base 6.5" speaker say's "2ohm Max 40w".

Thanks for the reply. I just received 4 ohm Polk speakers. Will the 4 ohm make a large difference?
Thanks

The db651's have a sensitivity of 92db, so they should be easy to power. Should be OK. The reason Nissan/Clarion went 2ohm was to squeeze every bit of volume out of the unit without concern for sound quality. If you don't like the results, you could add a small 2channel class D amp to liven things up. I would consider a Head Unit upgrade first, as the base radio attenuates certain frequencies based upon volume level from my experience(plus lack of input's).

And when you say 20w RMS, I hope you mean 5w RMS x4 speakers. There's no way that thing puts out 20 to each speaker.

Yes, it's unlikely that the base unit puts out a clean 20w RMS @ 4ohms, but when you factor in 2ohm load and max distortion @ 1Khz, it might come close. Doubt it would be CEA 2006 compliant though

. Remember that only 2 channels are driven on the Base model.
