Recommended RMS

[brendan_121212]

Hello,

I am looking for a simple audio system, and I have come across a Sony CD/MP3 receiver with 208 Watts max (23.3 RMS X 4; 52 X 4 Max) I found some 5.25 in. Sony Speakers with a Recommended RMS of 45 Watts. I am wondering if this will cause any problems with sound quality or if it will damage any of the equipment if I use this comfiguration. P.S. I am planning on using 3.5 in. speakers in the dash that will use up the other 2 channels.

Thank you very much.

Head units are usually insanely overrated in RMS wattage. It's doubtful you'll see any more than 10-15w coming out of each channel. I mean, look at the fuse on the HU. Probably a single 10-15A fuse. Look at an amp that puts out around 25-30W RMS, chances are it's got a 30A or higher fuse.

Everything Sony makes is also insanely overrated, I had 4 Xplod speakers in my car with 30 watts to each (rated at 50W RMS) and they all blew. I don't think they're safe with 1/2 the recommended wattage.

What's your budget? There's got to be better deals out there...

"sony" and "sound quality" should not be used in the same sentence together unless the words "sucks for" are inbetween them.

You could find some better speakers for the money that will sound ALOT better for the same price range.

if speaker_rms >= amp/HU_rms, you're the safest. If amp/HU_rms > speaker_rms, if you're not easy on the gains you could blow the speakers

Ok, I have another question, can you bridge channels on a h/u's built in amp?

 

[tobz 10+ year member]

No, don't bridge channels on the H/U. Also, H/U's will have high distortion and can be driven into clipping really easy. You will be fine with that equipment, but after purchasing it, if you can save up for a 4 channel amp, that would be ideal, and result in a huge increase in sound quality.

i would try to get something a bit better than those speakers. they can't take squat all for power. run them off the head unit but thats it, do not amp them.
