Either give me a call or come back to the shop and I'll personally see to it that your situation will be corrected right away.
If a noise filter was used it will be removed and a proper solution will be applied.
Keep in mind that current demand may also be responsible here, so I would check the battery fluid levels (if lead acid type), and check the charging system to see if a zener diode has popped in the circuit.

yup, those extra 'loops' of rca must cause the infamous 'ground loop'... hahaha...
Your problem is more then likly due to noise getting into signal ground at your source.. the only sure fire way to cure this is to ISOLATE power ground...
sometimes disney can solve or at least reduce the problem, or you'll buy a line driver, or a better source...
we'll see if your 'installer' can figure it out... lol..

Newb, until I can afford another amp and a sub, I will have to live with those stock 6x9s. The stock Prelude rear 6x9s actually come with a small amp and they actually sound quite OK for stock POS speakers.
Eli47, are you working at Speaker City? I took a look at your homepage and I think I recognize your face. If I am not mistaken you greeted me and helped me find the installer when I brought the car back to fix the noise.

Assuming that your battery supplies adequate power,
(check the amperage), I believe your problem does not lie in the equipment. If you connect all your grounds together, including the ground from your radio, that should cure your problem. Remove any noise filter/isolator that they may have installed, cut the ground from your wire harness (in-dash) and butt connect it toa 14-16 ga. wire and run it to the spot your amp is grounded. Then make sure your battery is properly grounded. Let me know what you find. Steve

Okay - if you are not happy with anything about a purchase at a store. I would suggest that you speak to a "manager" - hence me !! If we dont know you have a problem or are not happy with something, then we cannot fix your problem. What I would suggest you do is call me (604) 736-2077 at the store and arrange to bring your car in for us to look at what you're not happy with and fix it.
First thing - we did not use a ground loop isolator or noise filter in your system - period !! So you can look, but you wont find one !!
Second - the proper way to set the gain on an amplifier, is to turn the gain all the way down to nothing. Then you turn the head unit volume up to the max volume of 35 - in your case !! Hence gaining the full voltage of the pre-amp section of your deck, which is why you pay good money to get a 4 volt Alpine deck. Then you turn the gain up, if necessary !! It may be perfect without any adjustment on the amp.
THE REASON YOU WANT TO TURN YOUR DECK UP THE THE FULL VOLUME POSITION IS AS FOLLOWS : THE 4VOLTS OF PRE-OUT SIGNAL ON YOUR DECK IS NOT REACHED UNTIL THE VOLUME IS FULL.
Thats why your gain on the amplifier should be set as low as possible on the amp. This will lower the noise floor of the sound system and give you the best sound quality - which you are after.
So, I apologise for you having to come back in to resolve this problem, but asking evryone on the internet for the solution and getting several different answers - is not the way to get them resolved.
And just in case any of those so called "experts" out there disagree with me - if you don't have 14-years of experience in this business like I do - then I would suggest that I am probably right. And until i'm proved otherwise - I believe that setting up the system my way will result in you obtaining the best possible sounding system that you can have with the gear that you have.
Again, call me at the store and I will personally make sure that it is set up this way and that you are happy.
Now, I talked to the installer and asked why it was set up the way it was. He had set it up so that the deck was turned up the the maximum volume that the rear "stock" speakers could handle, this is why you are not able to currently turn the deck past 20 or so without things distorting. I will take care of this too when we get the car here !
Sorry for the inconvenience, but we will make sure you are happy. And next time you have a problem, talk to a manager - it is ther job to make sure that you are happy with your purchase.

You can't beat that. If the store manager wants to take care of the problem, then thats the ONLY way to go. I might add one thing though. All 4v Alpine decks achieve max output at a touch over 3/4 vol. . Everything else the man said is golden. He sounds very knowledgeable to me. I've been an installer/owner for 29 years. So listen to the man and take his advice. Grant, if you have any questions, don't be afraid to ask. Not all of us here are "so-called experts".

Hey G-Money, sorry if you felt I was stepping on toes there. I had assumed he would have brought up his problem with someone higher than the installer. I guess I shouldn't have done that. I agree with everything you say except you can set the gains more accurately with an O Scope, or even a level setting CD such as A2000 CD104.

The settings on the CDA9833 for the x-overs are defaulted at 0db. -6db would actually be zero for the Alpine HU. So at 0db it is actually boosted and max volume on the HU is extremely difficult to attain without distortion. I suggest -3 to -5 with 6db slopes for best results. I run the CDA9835 and was unable to reach max volume until I made those changes.
Hope this helps and I do agree speaking to a manager should be the first step in resolving any disatisfaction.
G-Money...a suggestion. Have your installer visit Alpines i-Personalize website and download and burn a CD-R for each Alpine HU that has the i-Personalize download feature. It will save them time and give your clients a well thought out group of settings to get them started with. I have found it an awesome asset.
