Check for ground loops.

Good rule of thumb is to keep all grounds in same location. Helps to cut out ground loops

Does alt whine just happen randomly? I don't recall hearing it before, but maybe I never noticed it cause I wasn't listening for it.

i would try to ground it in another spot {again}.

because this is when you got your whine right.

you may have got a BETTER ground, but maybe not a tru ground.

if you want to make sure, run a wire from batt- to ground on amp and

see if whine goes away.

this could be a quick jumper for test, you know run out side the car for test..

if this jumper fixes your whine then you either should keep looking for a better spot to ground to, or have someone help you run the ground from the batt-

to the trunk and use that.

also bad rca connections cause whine.

is the whine only on the subwoofers or all speakers + subwoofers

good luck

and it sound like you are starting to learn a bit.

we all had to learn somewhere{never feel stupid about this stuff.you will get it}

keep working on it.

The whine is coming from the tweets only. When one is plugged in, doesn't matter which side, no whine, but when I have them both in at the same time it has a faint whine when sitting in idle with the volume at 0. It makes a louder noise when I rev the gas, like a whistle.

Just take the car back to the shop man and tell them all the issue's you've had since the install. It sounds like you got your hands full.

I'll report my findings soon. I'm going to the place in less than a hour.

is your head unit a pioneer

Nope, JVC Aresnal

They fixed my grounding and whine issue. It was just a loose grounding. It may still be there but I can't hear it anymore so problem solved. They still owe me two windows and are telling me they won't pay for new ones... Uh oh... Might have to post a review on their install services.

i hate hearing stories about these "professional shops" ive got a honda civic, 80amp alt, running 1500rms with stinger batt and have no voltage drop problems or amps shutting off..... 800 rms and without trying to fix their screwup they want to sell him extra batts. what a joke.
if all that equip you posted on page one is correct why did they sell you an amp that does 150rms for 50rms speakers. doesnt seem safe to me.

the one time i had an amp that would get really hot, then go into protect it was cause i had a grounding issue. i had a common ground for 2 amps and a cap so i took advice from a friend i have that installs alot and shortened my grounds and had separate grounds per amp and never had the problem again.

did they even set the crossovers and gains on the amp? maybe his gains are set too high and hes overdriving the amp? maybe a combination of issues.

I am running 750rms on a class a/b amp and get no dimming of the lights or anything. Voltage rarely dips below 13 as well. Factory front battery, Kinetik 600 in back and no big 3 done either.

Now when I was running 1000rms plus, I was having problems though.

It it just a way to recommend spending more money. I bet what they would've done is installed a battery for me, find it doesn't work, fix the **** ground, and then still charge me and say it was the battery.

You're in Pittsburgh?

Hell, im no professional, but I can bet that my install wouldn't have caused any problems.

Ok, so i haven't read this entire thread but let me guess, team nutz ripped you off and gave you bullshit advice about equipment?

READ. TEAM NUTZ IS -THE- DEFINITION OF RIPOFF.

Ed Nuttal, the owner of "team nutz", is a fat ****ing idiot who thinks the chick at his shop will "settle the deal" when he quotes you at 50% above retail or MSRP for most of the shit they sell, INCLUDING RE. He will charge you $2,100 for a 18" XXX, when you can easily purchase it (FROM recommendations from RE THEMSELVES) for HALF of that.

Read my thread.

and FYI, there are some complete dumbasses in that thread who actually signed up after Ed told them to to back "his opinion"

HE wired a $1,000+ subwoofer WRONG. OUT OF PHASE. and ran 1,500 WATTS TO IT. which is probably why my sub now reads 2.4 on the VC's, not 2.0 or 2.1 or even 1.9.

You want GOOD, ACCURATE advice as far as setup goes?

Auto Illusions, Moon, PA.

They are awesome. Simple as that. They do anything.....oil changes...system installs...wheels...performance upgrades....you name it. I've been going there for years now, ever since my ex-boss referred me there, and they take care of me.

They installed my amp kit (ran power/rca, installed amp, grounds, etc. - EVEN DID THE BIG 3 without question) PERFECTLY...haven't had ONE issue yet, aside from the limitations of my system (i need another battery, h/o alternator, bigger amp, etc.)

They will fix any issues you have if you can drop some change. The -ONLY- thing i might say was a DECENT job nutz did was the box for my 12's. Anything else - equipment, setup, install.....GARBAGE. ed is in it for the money, and the "recognition".

the only reason people actually know about them is they give discounts out if you let them stick their stupid *** stickers on their car.

oh, how much i love rollin' up to some 19 year old who thinks his 2 12"s on 900 watts which he paid close to 2 grand for bangs, with TeAm NuTZ stickers all over his car when i just turn my volume up 50% and make his car tilt off the ****ing road.

Im not gonna read some 19 page alternate thread. But I will say this, there's no way in hell the things you mentioned would alter your speaker's impedance. If your speaker reads 2.4 ohms now, it always did.

then you're calling the developer of the subwoofer a liar.

wiring a sub out of phase and/or incorrectly, as i've been told multiple times, can possibly affect the impedance if you start running that kind of power to it for a few days while wired incorrectly

especially when the sub started to have a burning smell to it.

i'm not the greatest with electrical type shit, or even sub wirings/readings, but thats what i've been told but install shops and JR at RE.

second, i have no idea what ELSE they may have did to my sub, so yes, it is possible it was reading normal and whatever the **** they did to it could have damaged the voice coils.
