Too small of an enclosure could damage your woofer.

Tried that too my friend. It sounds like I have an angry box of Rice Krispies when I try that.

I tried a different set of RCAs, taken outside of the car to eliminate any RF or anything coming from any power source. Power and ground for the radio go straight to the front battery. Alt to battery is to chassis, less than .3 ohm from alternator to battery. I've tried radio out of the dash, in the dash, upside down, swearing at it, grounding the ground to the chassis of the radio, swearing some more. I did hook both of the radios up to a 12 volt jump pack for cars and zero noise. I also tried running another wire, dedicated, from the rear battery to the radio. Still noise.

I like to think of myself as a pretty smart guy. I've done a lot of installs over the years, and this is the first time I've got noise that I can't fix. I'm out of ideas. This is what I have done: Different radio - noise is less, but still definitely there. I get ignition noise with the car off, alternator whine with the car running. Different RCAs - ran them outside of the car into the trunk. Ground - was on stock harness, tried an 18 gauge right to the battery (front), now it's a 12 gauge right to the battery (front). With an Mp3 player hooked up where the radio would be, no noise. With the radio on a separate power supply (jump pack) no noise. I have my main battery and a battery in the trunk. Rear battery is fed by a run of 1/0 and a run of 3/0. What else can I try? No, it's not a Pioneer head unit either. One is a Panasonic, the other is a Sony. Tried also grounding the RCAs to body, gets real staticy. Another thing to the ground loop is that it's using the RCAs as a ground point. Comments/questions/concerns.

Do a glazing putty over the pits. Let it dry, sand. Don't use bondo glaze, get a good glaze like dolphin glaze.

How is it saving me hours of trouble? I tested the amp with muting plugs, so amp checks out fine. For some reason, it doesn't matter what head unit I use, or which RCAs, it uses the outer of the RCAs as a ground and introduces alternator whine/ignition noise with the key at ignition.

Most definitely grounding through the RCAs. The chassis itself is not grounded in the dash. I have a separate wire run from the battery to the radio for a ground.

Glad you guys mentioned that. I do not have the antenna hooked up at all. I do have a "hot rod" style antenna since I shaved mine, it's under the back deck and hooked up to a ground, however the antenna is not hooked up.

I had a similar scenario with the radio that was shipped to me, had to have been a bad radio, but if I hooked up just the constant power and any of the RCAs, i get power to the radio. Note that the ignition wire was not even connected. Another part to this is I got out my multi-meter, and checked the outside of the RCAs on the amp to the negative battery terminal. I'm getting damn good continuity on it, and I don't think I should be :~

The amp and the equalizer are on pieces of wood, and neither are touching the body of the car at all.

So something like this doesn't happen to me every day, and this is probably one of the first times I have witnessed it. Now I was doing some things, a buddy of mine let me borrow a known good working radio until my DVD player comes in. So I hook it up, it goes into my JBL eq, and then from there into my Opti 600.4 via RCAs. This is where things get weird. I had some car problems today, so I disconnected the negative from my amp and my EQ at the rear battery. The positive is still hooked up. I have the remote turn on into the ignition wire. When I got the car started, the amp turned on. There was alternator whine. Again, the negatives are disconnected. As soon as I disconnected the RCAs, it shut off. I tried with another set of RCAs, thinking it was pinched, same thing happens. Discuss please.

You made baby Jesus cry. Hi buddy!

dsoccer, the man never asked about hooking up an xbox to anything. Your answer #5 was vague and not entirely correct. Bad information is almost always worse than no information. And if the OP is a noob, how is he supposed to know which ones are correct?

I can't believe how many wrong answers have been given so far...

1. RCA is the company who made it 2. You have to worry about left/right speakers. The tip is positive, outside ring is negative. 3. Speaker wire 4. Absolutely, so you're not out of phase. 5. The power to the speakers doesn't have nearly as much amperage going through it as an amp would.

Anything that Zed has made most definitely.

Don't use bondo. Use something like evercoat, and use a good glaze.

Possibly... Is the noise there with the ignition off (key set to accessory), and there with the key in ignition and when the car is running as well?

Much love, thank you kindly.

What track is in ?

Yes, it'll be in tomorrow. Lanzar single din DVD player.

Alternator was tested, it's bad diodes. So I'm getting some AC voltage love, which would explain the cooked radio

Try purple power, wd40, simple green, or goo-gone.

Splurge, spend the money for a new 4x8 piece of MDF, and redo the box. We can help you do a slot port. As for the port, without a lip, you have nothing really to hold it. I would have made an MDF ring and glued that to the pvc, and then glued the ring to the box.

Did you tell them that you know me? That's a shoe-in for sure!
