where did go wrong wiring?

harobkr90 · Post by **harobkr90** » Sun Nov 30, 2008 12:15 pm

i'm at work so ms paint is all i could do to show how i wired my subs.

that's how i have my subs wired but i have to turn the sensitivity and bass boost all the way up to get any real output. my head unit puts out 2.5v.
the xenon manual says that the outputs are wired parallel. so is my final load 4ohms?

also, my hu can be turned up to 40 but anything turned past 15 is almost too loud. is it the hu? should i get a line driver?

any tips or questions on more info shoot em my way please.

Looks like you have your subs running a 8 ohm load and your running them in stereo mode. There for each sub is only getting around 75 watts per coil and is way underpowered. You need to wire them up bridged so the amp see a 4ohm load and get the most out of your amp. Check this link out and it will help you wire everthing up right.

i thought i had them wired as shown in option two of that page.
since the voice coils are wired in series and the speakers are then wired parallel inside of the amp. so i should move both negatives to the far right terminal and both positives to the far left terminal?

Yup. I had a problem with this too. You want both + leads and both neg leads together. That would be series/parrelell. Should rock after that

shweeeet. i'm ready to jam.
i'll let yall know how it goes.

Don't forget to turn your gains back down before start jamming again.

harobkr90 · Post by **harobkr90** » Sun Nov 30, 2008 3:04 pm

i'll double check and make sure they're turned down, same with the bass boost and the head unit zeroed.

thanks for your help.

this install is totally temporay, wires flying everywhere but no crossing signal and power. and a prefab box(yikes) until i make my amp rack and new box. i'm just too impatient.

harobkr90 · Post by **harobkr90** » Sun Nov 30, 2008 8:20 pm

well, not very impressed, it made a little difference.

to get the same output i was getting before i only had to turn the bass boost to about half and the gain/sensitivity to about the same spot.

the box theyre in has no divider in between the subs, could the subs palying against each other in the same airspace render the output?

i say double check ur sub coils for wiring(manuel); i did this once with a set of diamond audio subs; i wired the coils to where my amp was seeing a 8 ohm load-but, im not very familiar with the xenon series of amps, or idq subs--

harobkr90 · Post by **harobkr90** » Sun Nov 30, 2008 8:52 pm

man, this thread i have a ton of spelling mistakes.

the manual says:
impedance: 8/2

so you can wire both 4ohm voice coils series up to 8ohms and parallel to 2ohms.

hmmmm.

I'm with Christian double check your wiring first. Are you running these bridged L+ and R- ? Or are you useing both channel in stereo? What size enclosure are you useing?

Post by **Jacampb2** » Sun Nov 30, 2008 9:21 pm

Um, the amp is a x600.1, according to his pic, that means it is mono, and tying the two +'s and two -'s together at the amp did absolutely nothing. You can't bridge an amp that is already bridged, or a true monoblock. If it is really wired as in the picture, he IS presenting the amp with a 4ohm load. It is basically two 8 ohm drivers in parallel.

What does, "but anything turned past 15 is almost too loud." mean? The subs are to loud, the over all volume is to loud? Are you running a seperate amp for mids and highs? If you are, then their gains need turned down if you want to use more of your HU's volume range. If you are using the HU's internal amp, then you are screwed, there is not going to be a way to adjust it's internal amp seperate of the volume.

A line driver would probably be of great benefit to you. From what I understand, the xenons like input voltage. A HU with 2.5V output probably realistically puts out around 1V RMS.

Also, if you haven't done so, read the threads about setting your gains with a DMM, at least you can measure and find out what kind of power the amp is putting out. It may be making it's full rated power, and the subs simply are being under driven.

Later,
Jason

Not if you wired them correctly, but if you have one out of phase with the other(wiring reversed), then yes, you should hear almost no bass output, but they should be moving like gangbusters.

ok, so i have it wired correctly.

anything turned past 15 means that, my 6.5s and 6x9s are powered by the headunit and turning it up past 15 starts to distort. so no mid range/high amplifier.

the subs are 250w rms, so i should be over powering them a little bit.

harobkr90 · Post by **harobkr90** » Sun Nov 30, 2008 9:34 pm

they're not out of phase. double checked.

i can check again tomorrow and see.

Yea my bad,youre right. I didn't see the 600.1 I was just going by his drawing.

harobkr90 · Post by **harobkr90** » Sun Nov 30, 2008 9:39 pm

and for the enclosure, some prefab junk.

waiting til i have some extra time and garage space to make the box.

as Jacampb2 already touched on, the amp is wired internally to be "bridged" regardless of the + and - combo you use.

at 8ohms he should still be seeing about 400 watts.

i would test the voltage coming off the anp and go from there. that thing has PLenty of power for the idq's

harobkr90 · Post by **harobkr90** » Mon Dec 01, 2008 3:21 pm

my 600.1 birth sharted 612watts.

wish i got one of those pushing ~800.

i'll play around with tuning and get out the volt meter and see what i come up with.

Post by **Bfowler** » Mon Dec 01, 2008 4:14 pm

you do^ they are all the same. the earlier runs had a more generic birthsheet from the build house. the 800+ ones were done by PG. there is no parts change or anything, all are the same.

harobkr90 · Post by **harobkr90** » Mon Dec 01, 2008 4:18 pm

so the 612watt birthsheet is false/all of them got it?

harobkr90 · Post by **harobkr90** » Fri Dec 05, 2008 1:42 pm

can i wire one sub @ 8 ohms just to see what happens?

i'm still not getting the right power out of it.

i have yet to play with my voltmeter yet, i know, i'm lazy.

what does the xenon do at 8 ohms?

drivingdadevil · Post by **drivingdadevil** » Fri Dec 05, 2008 3:12 pm

You would be better off just wiring one at 2ohms.

harobkr90 · Post by **harobkr90** » Fri Dec 05, 2008 4:36 pm

if i wire it at 2ohms, i'll be sending well over 600w to a 250w rms sub.

Post by **stipud** » Fri Dec 05, 2008 6:52 pm

Do you have a multimeter? Hook it up to your subs (with the amp disconnected) and tell me what the resistance is (Ω).

If you can, check both the subs separately and make sure they have a similar value.
