Did you check the cables inside the box, impedence of the speakers, gains, fuse?
-
You know and I know that we know that we're no dummies. When we both get stumped, we're stumped! I fried both of my 8's in the rear deck simultaneously, magic smoke and all. Don't wang and plug in rcas, speakers don't like that.
-
It did this with two other batteries. Both have been replaced. It did it when I had the temple of boom initially. I wanna get it fixed so I can play the volume down some
-
Yes, I have the battery grounded. I have one run from the front battery (3/0) going back to the rear battery, and I also have a run of 1/0 grounded at the engine going to the rear battery. With or without the 1/0 connected I still get noise.
-
The problem with most of the cheaper ground loop isolators is of course you lose a lot of your midbass, since that's what the frequency the noise is. It's a 1997 Pontiac Sunfire.
-
The only thing that totally eliminates the noise is of course hooking any of the head units to a separate power supply. I have zero noise that way. Even with a ground right slap dab on the same terminal that the amp is on (back battery), I still have alternator whine.
-
I had some noise with my old amp also. Old amp is in my buddy's car and it has zero problems. On the Panasonic the internal amp is defeatable, and I did turn it off. Made no difference. I've tried three head units now.
-
Yes, just the 4 channel.
-
Yes, tried grounding the RCAs, made no difference to the sound brother. That was one of the first things I tried. When my ground was at the front battery, it sounded real bad, like rice crispies when I'd try to ground the RCAs. Now it makes no difference. I've quadruple checked every connection, made sure nothing's shorting, any audio wires that cross the power cables go 90 degrees to eliminate any RFI.
-
Noise is back. I ordered a noise filter to go inline with the radio's constant power. We'll see what it does.
-
Update - I removed the front ground and ran a wire from the rear battery as a ground. Noise is virtually gone. Very faint alternator whine now, and even that is intermittent.
-
Absolutely turn the loudness off. I never use it if I'm using an external amp. It's clipping your speakers to high heaven.
-
That is correct. A radiator is usually a cone and some sort of basket without coils or magnet. There's a shaft sticking out of the back of the cone to bolt weights on. The more the weight, the lower the frequency. It'll act like a ported box since the radiator(s) would determine the enclosure tuning.
-
Try a positive wire from the alternator straight to the battery.
-
Have a 38 hertz tone ready incase you need a defibrillator!
-
Wife leaves and I have to sell the house FUCK THAT
-
And minimal displacement of the radiator. The only setback is you'll have to have a face somewhere to mount said radiator.
-
That is a beautiful thing
For those who don't know, passive radiators change the tune lower the more weight is put on. -
-
Get silly and build an isobaric setup for it. Or an 8th order bandpass.
-
Its probly better that you don't know!
There isn't any reason to manipulate a manufactures speaker.
Adding mass means to glue stuff to the cone to make it heavier and can also damage a woofer very quickly if you don't know what you are doing.
Absofrigginlutely. *cues passive radiators*
-
I do have 12 gauge for my power and ground now. Same deal. I'm wondering if tying a ground directly to the 4 channel and the head unit is going to make a difference?
-
how can a small enclosure damage a woofer?
small enclosures usually are peakier in the notes that they play, meaning that some notes are much louder than others. and small enclosures makes the woofer need more power to get the same output as if it was in a larger enclosure.
If it's too small of an enclosure, the backpressure of the air behind the woofer could cause mechanical damage.
Box rise is a factor, and also the smaller the enclosure the higher the frequency of the tune. In order to get a lower frequency, mass needs to be added to the cone of the woofer.

Keep looking for the magic smoke coming out of somewhere. How are your sub amp gains set?

Redid my box but still have a problem

Are the subs dual 2 ohm or dual 4 ohm?
