I wonder what ones you guys use and like ? I know I have a cheaper set in my car and wonder if it could be hurting my systems sound.

So which one do you guys like and how much $$ do you spend on them..and the best place to buy them ?

I need couple sets with smaller rca heads because my amps sit close together.

have a good one

 

Just curious about your other equipment. Buying more expensive cables may not be necessary depending on your current setup.

 

do you have alternator whine if not dont worry about it. truth be told i use sub 10 dollar cables in 95% of my installs

 

I have no engine whine or other engine noise , I have stinger I believe. Middle of the line i think... but the rca ends could be a bit tighter on the amps.

I found a guy today who knows his $%^& , he messed with my HU and amps a little and it sounded a little better... I just dont have any mid-bass in my car.

I have a Kenwood dnx 9960 , 2 diamond d5 amps and ID 5.25 ctx in the rear and ID IDQ d2 v3 sub, and memphis 2 ways in the door and a set of ID CTX 6.5 comp. that I had in the car but took out while looking to figure out my "no" mid-bass issue. It makes no sense. The ID "should" have decent med-bass.

I might have a wiring issue, but since I'm not tearing my car apart myself I don't know what it might be. It seesm like a switch could be thrown and the whole thing would wake up, but whats the switch ?? I can't find it in the HU, no one has found it on the amps.

Could it be wired wrong some how and be having the bose amp getting in the way ? The installer use a os 2 bose for the Kenwood, but he orig had the stock bose door speakers running while I was waiting on the door plates to come in. Maybe he mis-wired something or took a short cut and got something wrong ?? The car has never had the full rich sound it should be able to have...maybe I don't know the Hu well enough ? I wish there was someone in the area from the board who could help me. How far is Utah from Az ??

 

Sounds like you have several things to check.

First and most important is to make sure your door speakers are wired to the Diamond amps and not to the Bose amp.

If that's true, check all of the crossovers on everything to make sure they're set to high-pass and set to a reasonable frequency level. This for sure includes your amps, but could also be on the head unit itself, and possibly on the crossovers for the door speakers. Start with something like 80hz for the crossover frequency.

It's also worth checking to make sure you didn't do something silly like hook the woofers in the doors up to the tweeter outputs on the Memphis crossovers.

RCAs are most likely not your problem. I'll bet you've got something set somewhere that is wiping out audio in the 100hz-500hz band.

 

Thrillhouse , you are thinking ths same way as I am. As of right now I have no sep. crossovers in the doors because the front speakers are 2 ways. I need to double check the wiring of the speakers. It looks like i have new wiring from the amps to the front of the car, but I think he could have used wiring from under the dash to the rear speakers. I understand that if he tapped a wire before the bose for the rear speaker wire then I have the bose amp itself probally doing some bad stuff to the signal.

Is it true that GM runs some speakers out of phase from the factory ?

Does anyone have pics of thier install of a bose OS2 adaptor ? maybe I could compare mine to it ?

thx

 

With your setup there should be nothing hooked up to the Bose amp at all(assuming you have one 4 channel amp and one mono amp for the sub). The RCAs should go into the back of the head unit and to the amps. One set of RCAs for front, rear, and sub each. There should be speaker wire running from your amps to the doors and rear pillars with the ends at the amp hooked into the outputs of the corresponding RCAs. The amp powering your front and rear speakers should be set to high pass filter with the frequency at 80hz. The amp powering your sub should be set to low pass filter, also at 80hz.

In looking at the manual for the 9960 I would start by making sure it is set to single zone with the EQ set to flat. Disable or turn off as much of the SRS WOW stuff as possible. Set surround control to bypass. Go into audio setup and make sure the crossover networks are set correctly. Front and Rear should be set to High Pass at 80hz, Sub should be set to Low Pass at 80hz. Reset all the car type and speaker location stuff to default if it has been changed.

The idea with all of this is to get the head unit set to do as little processing to the audio signal as possible, so you can start with a clean normal signal. Once you have everything set correctly, see how it sounds. If you want to do a little more diagnosing, download some of the frequency sweeps from http://www.burninwave.com/ and burn them to a CD. These will generate a tone that will sweep from low to high (or high to low). it should play smoothly with no major changes in volume. If you hear a very noticable dropoff in sound, that's where your frequency problem is. You can try something simple like tweaking the EQ up in that frequency, or you can download a specific test tone and see if you can figure out exactly where the hole is.

 

thanks for the info... thats what a guy was doing to my system the other day. I still need to go into it and make sure all the processing is off like you mentioned. thanks for the info and link.

Something could be out of phase. Check your door ID mid-bass speakers. Swap the negitive with the positive on just ONE speaker and see if your mid-bass improves. Lots of time when door speakers are facing each other than can cancel each other's bass but treble is not affected. You can do the speaker wire swap at the amp to make it easy to do. Let us know what you find.

 

DAMN Your alive still
