CD Player Deck wattage. - Toyota Nation Forum : Toyota Car and Truck Forums

2006 Corolla CE.

it has CD Player, and was wondering what is the wattage on it. Cause i have JVC MP3 deck and was wondering if I should change it. Because with original deck I have now, the bass doesn't sound tight even though I crank up the bass.

PS: Is it easy to swap the deck? just pull out the interior and unscrew and that's it? just click in w/ right cable?

thx.

I didnt have the MP3 stereo but when I replaced my stock radio (just looked again to be sure) It was rated for 4Ohm Speakers....or 48W at 12 volts. Now there is no more info than that on the radio unit itself...so we can only guess if thats per channel, front and rear or per speaker.

I did replace my head unit, with a 200W one, it wasnt too hard to get in besides running a power wire I believe. I got it though crutchfield.com, they sent a package with the wireing harness for my specific car, an 08. They have a little system to select your car and it will tell you what fits etc. Its kinda a pain to get the stock one out since everythings so tight, definatly get some of those ply bars (there plastic)

oh~. so it's just swap the deck and click on thing? I did change on my 88 camry, so it shouldn't be much of a problem?

and my JVC deck is 25watt normal(?), and 50watt max.(per channel) so i guess wattage wise it should be quiet compatible...

but is toodling w/ equalizer of JVC deck will make the bass sound tighter? or only way to achieve that is to have new speakers? because lack of tight bass is the part of the reasons i wanna swap..

oh and thank you very much for exact info on that original deck!! : )

Yea if you want more bass you need new speakers. My stock ones were rated at 17.5W....New ones are 600 :-). There not amped since I got subs too, but the sound is still better. If your JVC is 50W max, and since your runnin stock (I presume 17.5 W speakers) then you can start distorting the sound since your head unit puts out more than the speakers can handle.

I just installed the JVC headunit from my old Corolla into the new one. It is also 50 watts peak per channel. You can definetly get some distortion at higher volumes but you would probably have to try to actually blow the speakers. I have the 6 speaker stock setup and it does sound good, depending on the song.

The non-JBL stock headunits significantly underpower the speakers, hence the extreme clipping (and distortion) you can easily get. The same door and rear deck speakers were used with the cheapest headunit and with the 180 watt JBL setup (plus extra tweeters). Therefore, that JVC unit is actually a better match for the speakers (17.5W continuous) than the stock one you have now.

I also have the 6 speaker setup in my '07 LE. Are the speakers the weak link or the head unit? I have the 6-disc in-dash changer. It sounds fair. Not great, not poor, but just fair. There doesn't seem to be a lot of range to the sound...the bass isn't real low, and the highs aren't very clear. What would be the first step...new speakers or a new head unit? I would prefer to keep the head unit, but would consider changing speakers (just the 4 large ones probably) if it'd be worth the trouble if I keep the stock head unit.

They are both the weak link, but replacing the headunit is the only thing that would really cause improvement. Any aftermarket speakers are only going to be more underpowered, and if the headunit is putting out poor quality sound, it doesn't matter how good the speakers are.

I'm living with my JVC unit and the stock speakers till I have time to part with the car and have a good set of components, amp, and a sub installed...I have it all, just don't want to part with her for a day, as I don't trust myself to do the install without either breaking something or it being butt-ugly.

A good aftermarket headunit will sound pretty decent with the stock speakers...they're pretty damn good as far as stock speakers are concerned...although that's not saying too much...

What model JVC HU is being discussed here?

There is also a lot of misinformation regarding RMS and PMPO ratings of the equipment.

gideon1331 · 03-06-2009, 09:25 PM

I have a KDR-HD30. I'm assuming most of the JCV mid-range units have about the same sound output...probably even the same amplifier.

It is easy to confuse RMS, Peak, and PMPO ratings...although I can't say I have ever seen a car audio component with a PMPO rating...usually only the cheapest computer speakers and things like that.

From what I know.

RMS: what the amplifier can put out, or the speaker can handle, on a continuous basis.

Peak: what the amplifier can put out, or the speaker can handle, for an extremely short period of time. A drum hit for example.

PMPO: what the amplifier can put out for maybe 1/1000 of a second with no regard for the level of harmonic distortion or damage incurred by the amplifier.

Stock speakers:
RMS: 17.5 watts per channel
Peak: Unknown, but likely to coincide roughly with the 180 watt Peak output of the JBL premium headunit (45 watts Peak per channel)

JBL aftermarket unit. Most others are very close to these numbers as well.
RMS: 22 watts per channel
Peak: 50 watts per channel

Yep, you pretty much covered all the bases.

lol I don't even bother with reading PMPO ratings anymore since most are a gross misrepresentation from the manufacturer anyways.

From my experience, most of speaker blowouts occur because it is not sufficiently powered by the internal amp of the headunit and this causes clipping and distortion that can prematurely destroy the voice coils.

It seems to me that Rdkill has the wrong idea of mixing up the ratings when comparing specifications.
