    14 RMS vs 22 RMS

    Hi,

    I bought a Pioneer DEHP8400BH but it says it's 14 RMS on the box and it doesn't mention the 22 RMS like on the website.

    I'm thinking to return it for a Alpine (CDE-133BT) since I don't need HD radio and all that stuff since I'm in Canada :P.

    Although, why the other brands (like kenwood/alpine) says the output of their head units are 22/18 RMS? Is it CEA 2006 certified also?

    Thanks,

    None of those make their rated power. And you won't hear the difference between that power anyways. They'll all make around 10w or so. And for future reference, the CEA certifications are inapplicable and relatively worthless.

    Re: 14 RMS vs 22 RMS

    The 22rms for the Pioneers is the rated power @ 5% thd. The 14rms is cea certified though. Check out the manual online and it'll be in the specs.

    Those few watts are not really a worthwhile reason to switch your headunit.

    Get a headunit with the options that you want & get an amp as mentioned. Even a small amplifier will make a world of difference when compared to headunit power.

    Head unit power is very low and will distort fast. You're going to need a amp

    I'd say under the seat. But I think just upgrading the head-unit will be a nice enough upgrade. If you change out the speakers to something decent, then I'd say get an amp. Regardless, a good, affordable, small-footprint amp that I would recommend is the PPI Phantom 900.4. : Precision Power PPI P900.4 (p9004) 4-Channel Phantom Car Amplifier
    These things have been going out of stock non-stop since they've been released.

    Well they might make 14 watts when turned up to maximum volume. But then you'd have a TON of distortion and likely clipping as well. I'd say you probably have around 10w of clean power. Regardless, you're not going to hear the difference between 10 and 14 watts. And you're still getting more power and cleaner power than your factory head-unit. I wouldn't worry about "power" on an aftermarket head-unit. That's not what it's for. It's there for cleaner signal, more features, more sound control, and more upgrade options.

    Re: 14 RMS vs 22 RMS

    yea you would see 10w rms from a hu at most. likely less. if you dont plan to upgrade speakers etc then why not use stock hu? idk what year your car is but most newer cars have decent stock sound and likely steering wheel contols, voice controls, nav etc. could be costly for the install kits as well. if its old then i understand and wouldnt worry about what the output rating is. they are all about the same. like said just stick with the pioneer.
