That advice is right on. Until you add an external auxilliary amplifier, the key to good sound is selecting speakers that don't need a lot of power which is indicated by a high Sensitivity rating. 90 dB (decibel) or higher Sensitivity is what you need for a stock head unit. And as said above, about the most RMS (real) wattage that a stock head unit can put out is 12-18 watts RMS. Forget all the other wattage ratings... Peak, Music Power, etc. which are more misleading to the uninitiated than anything.For speakers in a Jeep, you should consider sensitivity more than worrying about RMS.
As far as power matching, you ideally want the speakers and amp to maintain the same RMS rating; ex: 30w speaker should see 30w amp.
Your head unit is not putting out anywhere close to 50w. The actual output is likely in the 18w RMS range.
Find an amp that matches your speaker's RMS rating and you will be surprised how much the sound improves.
Rms and power has nothing to do with clarity. You're looking at this completely wrong.kdtomczak said:What RMS would yall recommend for clear, crisp sound and a pretty high volume, and the RMS for the amp.
Right now, all my speakers are rated at 30 RMS...but my HU is only putting out 50 by 4 speakers...so basically anything would be a nice upgrade
A well built amp with the gain sky high will still never fail, it just won't sound good.Ibuildembig said:I usually sell people a bigger amp than what they need simply because it will last longer not gained up all the way and will sound better. The money difference is minimal too. I would look for 100x4 to run what you have.
Sorry, you're right. I definitely did go too far into that. I apologize.Ibuildembig said:Your reaching way far into the words I said Derp. When selling a customer a larger amp over a smaller one of the same series, the money is minimal (usually less than 80 bucks). Most people are far from credible audiophiles and hardly require the THD of .0001, and wouldn't even consider a 2K set of components. That being said, 90 percent of jeepers are fine with the status quo that a cheap speaker such as a Polk or Infinity has to offer....although there are much better choices available if someone has to the time to listen to different ones themselves instead of taking peoples words for it.
Are you serious? If you are, that would be wrong. Matching the speaker impedance to the amplifier impedance is indeed important no matter what type of speaker you're talking about. Too low of a speaker impedance can damage the output stage of an amplifier, too high of a speaker impedance means the amplifier won't develop the power it is rated to, not to mention other problems that will impact sound quality.The only time ohms make a huge impact is on subwoofer wiring applications
