I have an 03 2 door!!! |

Moved to I.C.E. & Electrical |
Let me ask my neighbor...his mom works for alpine...and they got some sick stuff in their cars...hopefully they can get me a new tv screen... |
im talkin abou the setting on the Deck! not the wiring |
if youre using a completely stock system with that deck, all those settings wont change single thing in your sound. dont bother... |
It should say in the manual, i just sent my iva-d900 in 2 weeks ago for repair but the time correction is based off of the distance from the speakers to the drivers ear. There was a formula, i'll try to find it................ |
Owners manual About Time Correction The distance between the listener and the speakers in a car vary widely due to the complex speaker placement. This difference in the distances from the speakers to the listener creates a shift in the sounds image and frequency characteristics. This is caused by the time delay between the sound reaching the listener’s right versus the left ear. To correct this, the CDA-9815/CDA-9813/CDA-9811 is able to delay the audio signal to the speakers closest to the listener. This effectively creates a perception of increased distance for those speakers. The listener can be placed at an equal distance between the left and right speakers for optimum staging. The adjustment will be made for each speaker in 0.1 ms steps. Example 1. Listening Position: Front Left Seat Adjust the time correction level of the front left speaker to a high value and the rear right to zero or a low value. *1 Subwoofer speaker. CDA-9811 only You cannot change the Time Correction value for the subwoofer, but you can set the subwoofer's apparent position to the front by adjusting the Time Correction value of the front and rear speakers. For details, refer to the “ *1 ” on page 18. The sound is not balanced because the distance between the listening position and the various speakers is different. The difference in distance between the front left speaker and the rear right speaker is 1.75 m (68-7/8"). Here we calculate the time correction value for the front left speaker in the diagram on the above. Conditions: Farthest Speaker – listening position : 2.25 m (88-9/16") Front left speaker – listening position : 0.5 m (19-11/16") Calculation: L = 2.25 m – 0.5 m = 1.75 m (68-7/8") Time correction = 1.75 ÷ 343*2 × 1000 = 5.1 (ms) *2 Speed of sound: 343 m/s (765 mph) at 20°C In other words, giving the front left speaker a time correction value of 5.1 ms makes it seem as if its distance from the listener is the same as the distance to the farthest speaker. Time correction eliminates the differences in the time required for the sound to reach the listening position. The time of the front left speaker is corrected by 5.1 ms so that its sound reaches the listening position at the same time as the sound of other speakers. Example 2. Listening Position: All Seats Adjust the time correction level of each speaker to almost the same level. 1 Sit in the listening position (driver’s seat, etc.) and measure the distance (in meters) between your head and the various speakers. 2 Calculate the difference between the distance to the farthest speaker and the other speakers. L = (distance to farthest speaker) – (distance to other speakers) 3 Divide the distances calculated for the speakers by the speed of sound (343 m/s (765 mph) at 20°C). These values are the time correction values for the different speakers. 2.25m 0.5m 5.1ms *1 *1 Hope this helps :) |
I have that headunit and just go to their website and go to the i-personalize and it will measure it for you |
heh dont worry about time correction ish.....and as for the Xover, change that to flat to get more bass......i have my xover on flat |
can u post ur setting for ur Xover just to campare with mine! thanks |
I have the 9811 - I had the tweeter salesperson tune it for me. He used a special tape measure that gave you the seconds of time (marked right on the tape measure) which made it easy. The idea is that you're centering the sound dependent on where you most sit (drivers seat) and I have to say that after having this done I prefer it time corrected. I think you will need higher end speakers to realize the effects though - as Ludlam points out the stocks are crap and you won't see much from this....I'm running Boston 6.5 comps in the front and 6 x 9's in the rears. |
I agree with Ludlam too... I put a 9815 in my 01 coupe about 4 months ago. I had already purchased JBL 605C comps for the front and GTO936 3-ways for the back, but left the factory cones in there for a week just so I could compare. When turning up to a reasonable listening volume, the distortion became very evident... those paper things just don't like to be pushed. Even though they were made by Pioneer, they were guided by OEM specs, rendering them crap. After hearing the extreme difference in clarity between the two, I can gladly say that the painful install was worth it. Removing the entire rear seat, trim paneling and trunk spring to get to the rear speakers!? :-bs: But again, it was well worth it... etdigitalis "The best headunit in the world can't overcome inadequate speakers." - Alpine's Website |
I think the stocks are 15 watt max - very disappointing. I have never had very good experience with Pioneer audio. Ran a pair of 61/2's in the front of my Neon and they never sounded very good. Had to use an active crossover to filter out low end... |
