Currently i have a Kenwood KDC-MP425 deck that is 22 RMS, pre amp 2 volt.
I am thinking about getting an Eclipse CD 3000 deck, it is only 14 RMS, but pre amp is 5 volt.
I have factory speakers with Infinity amp with Infinity Kappa sub.
Should i change to Eclipse deck but lowing my speaker RMS? Any advice is welcome.

 

The RMS of the stock speakers is 20 I believe, with peak being 50. I'd get the Eclipse deck. The higher voltage pre-outs are worth it IMO.

 

Don't woory much about the difference betwee 14 and 22 watts "RMS". The difference in max output volume between them is only about 2dB SPL, and when listening to music at reasonable volume levels, you're most often using much less than 14 watts anyway.

 

Thanks for your reply, I will get the eclipse cd3000 once i sell my Kenwood.

 

5V preouts is great! I've seen 8V and heard of 9V, but that is just crazy!

The 22watts is the output for stock speakers. The Voltage output is for the RCA wires to the amp. You will get a more efficient and more power response from the 5V unit as opposed to the 2V.

 

The incentive for higher voltage preamp outputs is to lower the noise floor. Using higher voltage inputs to the amp enables you to use less gain (which will result in lower noise) while still producing maximum output power.

 

Thanks for your inputs, I went to circuit city today to check out the Eclipse cd3000, It is nothing flashy. The main reason i want an Eclipse is that it works with tc steering wheel control. The left **** is for the volume, and the right **** is for selecting tracks.

 

eclipse makes some great headunits, they arnt flashy, no graphics or anything till you get up to the cd 7000. they have amazing sound tho, well worth it.

 

You will hear a huge difference in sound quality. Go for it!
