with a mosfet 50w rms x 4 car stereo, will it be better to get 50 watts max rms component speakers or 110wrms

Question

What i have is a Pioneer double din FH-P5000MP and it supposedly has 50 watts rms x 4 unless its just 50 watts peak, and the component speakers im trying to get are either alpine sps-171 50 watts rms or the spr-17a 110 watts rms.

Answer 1

OK, easy here . . ..
First, what's listed on your specs are MAXIMUM PEAK POWER OUTPUT. That's refer to maximum ability of your unit to drive a single burst in period of milliseconds, in the lowest impedance. In short, that won't likely to happen.
In real world, a deck will only have 10-15W per channel, 20 at tops (I've installed hundreds of pioneer decks, believe me!)
It's the same with speaker, it's also peak power.
My suggestion is to find a speaker that match the power, or vice versa, the numbers are there for a reason.
Your 50W peak deck will provide enough output to a 50W peak components, and won't overpower it.
Sure, you can have better quality components that has 100W or more, but usually the higher the wattage, the lower it's sensitivity, meaning you have to push them with larger amp to have the same volume / SPL. And you also spend more money on more expensive speakers but you can't fully use it's potential, because your deck don't have enough power to supply it. It will sound good, it can (and should sound better).
Unless, you're planning to buy an amp to power the components later.

Answer 2

That all depends on the quality of components used. If the 50RMS x4 amp is a true rms like Memphis Audio, JL Audio, MTX, or JBL you can trust the rating, the Total harmonic distortion is important. Some amps are rated 50RMS at 10%THD and some like the Memphis rated 50RMS at .05%THD. The lower the THD the better. If you are talking about a head unit your true rms will not be what you qouted, head units tend to have a very high THD.
On the speaker side go for a good brand, for instance a 110RMS componant in a Pioneer will not compare to a 60RMS componant from Memphis Audio. Quality is a bigger variable than the power handling. A high power handling speaker does not mean anything if the speaker is going to sound like crap. Go with which ever brand delivers higher quality.

Answer 3

Pick whichever sounds better. As long as the speakers are rated to handle all the power that your amplifier can produce cleanly, then the power rating doesn't matter much. Just because a speaker is rated at 110 watts RMS doesn't mean that it won't sound great with 50 watts; the rating is its maximum recommended power, so anything up to that is fine.

Also, if you're talking about an amplifier, the 50 watts RMS x 4 rating is probably correct, but you said "stereo" which makes me wonder if you're talking about an in-dash CD player. There's no such thing as an in-dash CD unit rated at 50 watts RMS per channel.

Answer 4

You will want to rate your speakers close to output of your system. If you plan to upgrade later then go with the higher power units and see less performance in the mean time. If you do not plan to upgrade any time soon the lower power units will provide better listening quality with the system you currently run.

Answer 5

Get 50w rms speakers to match your amplifier. Most distortions in sound reproduction are contributed by under-powered amplifiers in relation to the speakers they are driving and may even cause permanent damage to your speakers

Answer 6

Buy the higher power speakers, this will give you ''headroom'' as far as not overloading and burning the coils on the speakers and having an undistorted signal.Sound will be much better.
