Thanks for the input. I run the subs in the trunk in a sedan. Sealed off from trunk, subs facing into cabin. It’s an SPL build.

Just a heads up people. I just finished installing a new component set. I made sure it was all wired properly, positive to positive and negative to negative. I wanted to double check everything with free polarity tester app from the iOS store. The new components all tested fine but my existing...

I’m chasing parasitic draw, my alt is failing the diode test, maybe. It becomes noticeable if the car sits for 2 days or more. It’s draining my plannano bank. It also did it when I ran Headways. I’ve checked numerous items then I found that I need to check the alt and make sure it’s not bleeding...

Thanks for both of your replies and suggestions.

I am building a birch ported box and after watching some YouTube videos one particular builder quickly says that he treats the inside of the sub box but he doesn’t say with what. Can I treat the inside of the box with clear polycrylic? Will it affect the sound or is it completely unnecessary to...

Thanks guys for your input. I recorded another video using another system & I see it happen there also using the same iPhone.

Has anyone ever seen this through their phone’s camera. The subs look almost out of phase but they have been triple checked. Even busted out the old 9 volt battery polarity tester. Both leads from the amp are the same exact length. All internal leads are the same length. Ohms out at 1 ohm so if...

Hello all again. This is just an fyi. I just finished installing a system in my son’s 2012 Nissan Altima. Big3 completed, XS power batteries front & back. After it was all done I wanted to check what the voltage was from the alternator to the front battery. I told my son to start the car & then...

You can push 4 gauge through the hood release grommet. Follow the hood release cable & push the grommet over. 0 gauge will not fit.

There aren’t any grommets. I have a Hyundai Sonata. I pulled the carpet back near the brake pedal & I found the place wear the clutch would go, I have an automatic, & I had to make a few holes into the sheet metal. I then had to use some tin snips & side cutters just to make a big enough hole to...

The OP claims to have an SFB 2000, Sundown specs are 5 volts on the RCA as the input max. 2v from the head unit is perfectly fine but the problem is most head units provide 2 volts at max volume. We just don’t know when his head unit is clipping. He tuned at 3/4 volume so we know it’s not 2v &...

When setting my gains I disconnect the subs. When I’m done the amp is connected to 2 12” EVLs at 1 ohm final load. I just noticed your location on your signature says Sarasota FL, I am in Port St Lucie FL. I am due east of you lol.

I don’t understand the question.

To be honest the sine wave looks better with the car on. Please keep in mind that while setting my gains the subs are disconnected. I am going to try to test the oscope on a couple of Skar amps I have in the closet, RP1500.1 & RP800.1 & see if the oscope is the problem or it’s just the SFB...

I re-ran the test using the oscope with the vehicle off. Unfortunately the fingers / noise was still there on the scope. Honestly I believe the noise was more prevalent as opposed to the vehicle on. Pictures below. At the end I turned on the car and set my gains to 55.16 volts per oscope, 52.15...
