i used an oscilloscope on my Kenwood KDC-MP238 yesterday, all flat settings, and it is clip-free at volume 34 out of 35 using 400hz, 1000hz, and 50hz.

i think we should have a thread where we have a bunch of headunits and info on when each one clips with what settings for future reference to other members.

Lol overpriced amp huh. Shows how much you know. I know folks. Dont be mad you run a piece of shit amp. You and all the other dont know bbetters can say man itd awesome its awesome and I got it for 125 bucks. Ive spent more on glue.

Clip city bitch, clip clip city bitch. 10's, 12's, 15's, goin up in flames bitch.

Pioneer DEH-4100UB Clip free up to 45
Alpine CDA-9886 Clip free up to 24

Both O-Scoped at flat settings, as always.

Some headunits are different, despite the fact that they are the same exact model number and everything. The numbers are good guidelines, but you never know until you put your equipment on an Oscilloscope.

I have had 9886 and 9887 both are pretty good and work fine.

I would say at 22-23 for the Alpine


Yup the Kenwood are 34 but exceleron don't seem to clip at full bore in my past experiences.

accordingly to what? the point of this thread is to help people that dont have oscilloscopes, to know what general volume (not always 3/4) they can safely turn it up to w/o clipping off the signal.

My 9887 is clip free on all the pre outs up to 34 out of 35. Even at 35 its barely noticeable. Thats all flat with the internal amp set to off.

damn you can turn your internal amp off? thats cool as hell. i wonder how bad the internal amp is clipping (using external mids and highs and woofer amp)

I think it also depends on the type of music played as well, i can play some dub and rap and may get clipping at 21/23 and then if i play some supertramp or some other classic rock i can go to 27/29 or more. This is on an alpine cde-102.

Had it on my TPI 440 yesterday. Thats what I saw, dont know about yours. Im going out to do some more tuning tomorrow. I will do it a second time to confirm.

1khz tone on the front and rear and a 50hz tone on the sub out

how did you figure that out? what frequencies did you use?

edit: i used an old school oscope and did 3 different frequencies and each one was a clean wave. only 35 BARELY clipped the wave off

edit 2: sine waves were played via ipod video 5th gen into the aux port

edit 3: reading > me. are you talking about the 9887 or the kdc-mp238?

I used sine waves I downloaded from ROE. Played from my Ipod 2gig Nano, dont know what gen. Ran thru the Ipod cable to the deck.

I saw the same thing, at 35 it barely clipped the wave at all. I set all my gains at 33 just to be sure.

So far im loving this deck. It blows away my old 9856. The difference in sound quality is night and day. The EQ adjustments will take a while to get used to but I will figure it all out.
