Amp probs? NEED HELP from the audio guys.

[kizzo]

So i have a profile ca600 running a set of cadence cwm-6 6.5 inch components up front. I reinstalled the amp today because i was moving stuff around and now my components arent acting the same and i think i might have messed something up. Both of comps are on, but it seems as if they are leaving out notes. For example if i were to listen to a rap song like Yung Joc or something you can hear deep voices coming through the midwoofers but you cant hear the kick drum/deep bass bump. And lets say there are multiple people rapping/singing at the same time, you can only hear one of them well, and the other one sounds phased out like its coming out of a blown tweeter or something. Im 100% confident on the Power, Ground, and remote wire. 100% sure on the rca's, and im about 85% confident about the speaker wiring to the amp. I thought maybe i wired them out of phase or something so i spent around 30min just mixing them up and trying but it still sounds the same.

Could this be a problem with the amp?

Is it possible i somehow messed up/fried my crossovers or something and this the result of that?

[2loud2k2xd]

i would check the eq setting on the amp. maby you moved a setting. also, double check the wiring from the amp to the components. 3rd, if you have a tuning cd, pop it in and play it. the cd should have all the low/mid/hig freq's you need to tell if you have a problem. also, double check the settings on the deck. murpheys law can sometimes strike in weird ways.

[kizzo]

i checked all of that i believe. do you know where to dl one of those tuning cds?

[2loud2k2xd]

pm me your addy and ill mail a copy out to you on monday (tomorrow ill be in surgery). a copy is not as good as a origional one, but it will do for now.

i still think its your amps crossovers not letting the signal come thru. high pass should be at 100hz or 125hz and sub at 80hz. if your still getting sound out of all the speakers its not a wiring issue, but rather an eq/crossover issue.

[kizzo]

Thats what im thinking, i actually found a place where i can download the tones i think so dont even worry about it. Thanks for all the help though i seriously appreciate it. If its not my AMPS crossovers, could the be my components cross overs? Do you know how to check if its one or the other?

[2loud2k2xd]

look at the amps settings.dials. look and see if they are in the correct eq range. then check the seperate crossovers for the components. your components came with their own crossovers, right? if those 2 check out, then you need to investigate the speaker(s) themselves. check each speaker. but before you check the speakers, double check the deck settings and make sure you done have anything cancelling eachother out.

and the test tones are sine waves if that helps. if you go to usaci.com or dbdrag.com..either one of those forums will have the test tones ready to download.

I mean all i did was move the amp over when i reinstalled it. So i know that the crossover setting for the components are good because ive never changed them and they worked before i moved the amp. I got it pretty much narrowed down to the amp, so im gonna try and hook up one of my friends amps to my comps and see if i get the sale stuff

[2loud2k2xd]

any updates? im alive and kickin man. bored as all hell tho. let me know if you need some help kizzo.

[kizzo]

Yea i cant get any other amp so i dunno what im gonna do. Is there a way to check if the problems are from the crossover on the amp or the crossover on the speaker comp set?

[2loud2k2xd]

look at the crossovers for the components. most are clear and you might be ablt to see if somethings burnt. did you have all the power off when messing with the amps? if you left the power on while movinbg and re-wiring things, you might have blown something in the crossovers.

[kizzo]

yes i actually was in a rush and i had the amp on while i was hooking up the speakers. it might be the crossovers on the speakers ill check em out.

you know where to find some cheap replacement crossovers?

[2loud2k2xd]

most likely ebay. you could also check out a few sound forums. usaci.com thecarcound&performance.com, sounddomain.com, dbdrag.com. alot of guys sell their old comp stuff for new ****.

[kizzo]

somethin like this would work?

[2loud2k2xd]

yup...

then resell the tweaters on ebay for 20.00 and recoupe some $$ back

[kizzo]

i feel retarded paying 30$ for a set of comps i paid 100 bucks for but yea thats prolly what im gonna have to do.

i also got a new ground loop noise i gotta deal with probably thanks to pioneer. you ever have any noise issues with ur pioneer deck?

[2loud2k2xd]

i had a decent ammount of noise from my 960mp. but i just bought a new 860mp and i have ZERO!!!! noise now. i made NO audio/amp/eq adjustments since installing the new deck. but i also have 3000+rms watts running thru my car. i have a simple homemade ground loop isolator noise supressor that literally costs about 0.50 to to. i have yet to use it with my 860mp tho. but i know 100000% that it works.

try and moving the amp grounds to a new location. 3' or less for any ground!!! no 2 grounds should be bolted together. all paint must be removed for a proper ground. and try to replace the deck ground out of the factory spot. if you remove the deck, on the right side of the deck area, there is a metal bracket with nothing on it. i screwed a new ground there and it worked well. but i also have my component amp tweaked rather high. and i only get noise from my component amp. but like i said a bit ago, NO more noise. yippee :D

if you like send me a pm about the homemade ground loop isolator, or ill make one up sitting here to show you guys how to save 20.00 and not buy one from online/store. ill post up pics of in a few minutes. but ill make a new thread so its easier for everyone to find.

dave

ok, ill make a write up now. give me a few minutes to type it all up.

kizzo, the diy is up.

[kizzo]

i see, yea i dunno about pioneer and noise it seems to be pretty common. but anyways, i looked at the ground loop isolator you made and thats pretty much just grounding the rca's correct?

[2loud2k2xd]

yes, thats all a ground loop isolator does anyway. but with out the 20.00 box.

[kizzo]

haha thats awesome. i think the majority of the noise is coming from my amp though, you can the same thing just backwards right? By that i mean, i can ground the rca's going into my amp.

[2loud2k2xd]

yup, you can ground the rca's. just do it from behind the deck and not by the amp. you need to block it at the begining of the source (deck) and not at the end of the source (amps).

remember, read the warning i posted in the DIY. please becareful and double check the wiring. i dont want you or anyone jacking up their stereo. the worse thing that will happen is you will fry the rca output on the deck and fry the rca's.

[Ugzz]

^^ frying the outputs on the deck would be bad.. then youd have to go back to just speaker wire to the speakers or high level input which would sound way worse ..

good info though, looks like you got this one tackled 2loud

[kizzo]

hey 2loud, you think these will work?

[2loud2k2xd]

yup, but the thing that makes me question this is...... "great for making home theatre speakers"...... what the guy said in the auction. other than that, id buy them.

[kizzo]

heres the comp set it came out of.

only thing im worried about is the fact that im running about 125rms through each component and that set is rated for 60rms and 120 max.

whats your take on that

not sure what components your talking about?

oops

[2loud2k2xd]

so your just asking if the crossover will be ok with the wattage you have? then YES. if your asking if the component set listed above will be ok with the wattage from your amp, the answer is still yes. just make sure you "tune" your amp and not kill the gain all the way up and you will be fine.

90% of all blown systens in cars are from not properly tuning the system. ive had the same sub for about 3yrs, and the same sub and component amp for 4 yrs, and NEVER had any issues with blowing speakers..even when competing.

[kizzo]

yea im not changing the comps im just getting the crossover. so if the crossover is good then thats all i need.

[2loud2k2xd]

yup, that crossover will do perfectly well.

[kizzo]

turns out the baztards at DA use 8ohm tweeters. Good thing i bid on crossovers for 8ohm tweeters and i have 4ohm ones. Im gonna try and get a refund. Sweet deals goin on nowadays. DA cant build anything themselves.

[Ugzz]

i wouldnt have even thought to check.. wow thats rediculous..
im actualy a DA fan, hey as long as it sounds good right?
does suck it wont match what you have though.. have you attempted contacting the co. and getting a direct replacement, or pricing it at least.. you neve know..

[kizzo]

yea im just gonna get some JL ones.

Diamond is a company similar to Elemental Designs. They dont make their own drivers, they make the actual woofer with surround but the drivers are made by some one else. Last i heard it was RE that made drivers for ED (i think). It's a smaller company for DA. Im also a really big fan of DA i got 2 12" D6's and the sound quality at high power is some of the best ive heard.

Call me crazy but id take DA subs over anything JL makes (maybe not the w7) and a couple other good SQL subs like ED and Cadence.

[kizzo]

Just wanted to say i solved all the problems. I actually put a new crossover in on the left side and now both work, one is JL Audio and the other is Cadence and i cant tell the difference?

For the engine noise problem, i simply grounded the rca's like this http://www.caraudio.com/forum/showthread.php?t=147694&highlight=alternator+whine

best solution yet for any of my noise issues works perfect.

[Ugzz]

^^ very interesting, never even heard of doing that. Makes good sense 2!

as for those D6's after reading NOTHING but good. they are my next sub :D
they are on my wish list right now and sonicelectronix has em Wayy cheap

[kizzo]

Yea theyre rated at 600rms but they can take a lot more then that. Good subs right there.

[BlueRush]

LOL...

1st... You are running two different crossovers on the same type of driver? Gonna sound different, YOU may not notice it, but it WILL sound different.

2nd... If you have ground noise from a Pioneer deck, and it's under warrenty, get it replaced. By hooking up RCA's with a Pioneer deck, the DECK MUST BE OFF!!! If not you will blow the IC outputs and you WILL HAVE NOISE. Also, ANY NOISE FILTER is a bad idea, even just grounding your RCA's = BAD. You are altering the signal which will have a negative effect on the overall performance and sound.

Anyone who has ground noise should FIND OUT WHERE IT'S FROM, atleast if you want decent sound.


my $0.02...

Well if i cant tell the difference i could care less, thats all that matters anyways.

And what are you talking about the deck must be off? I always turn all my stuff off when im hooking up wires. If i ground the rca's and that eliminates noise, then thats a good enough solution. Obviously i cant run rcas completely noise free thatd be almost impossible. Even if i did it wouldnt be worth it. If my deck WAS under warranty i would prolly get it replaced, it isnt, and even if it was grounding rcas prolly takes less energy then getting a new deck.

i totally agree, personally when i used to have all the time in the world i was a Super perfectionist and it had to be done 100% correct and have the best sojund.. but nowadays im super busy, have like no time anymore and if i can find something that works and sounds great to my ears, thats all that matters.. -im still a perfectionist on sound, but nowadays, as long as it works and sound good.. whatever
