Subwoofer issues Options

[Liam_c]

Hey everyone!

Just got my sound setup all put in (nothing huge)

Whats the best way to secure a 12" Sub box in the boot? So its easy to access the spare tyre etc.

Also, when i have my sub cranking at night (headlights on full beam) they tend to have a slight flicker with the beat. Could this be from a bad earth? Or do i need to upgrade my battery? Or even my alternator?

a capacitor does not do anything. many say it helps giving extra boost blablabla, but at the best, it MAY remove some noise from dynamo and reduce ripples.

it is only good for:
Jewelry in the trunk to impress chicks with a cylindrical shiny thing,
Extra weight
A very poor and expensive connection point
A projectile in event of a crash
A expensive rolling pin if you gotta cook something in your trunk on a trip.
Something you can brag about: Hey maan check this, ive got a condensator to fix all my battery problems.

A Capacitor only delivers around like 100W over almost 1 sec... well worth the bucks!! cheaper to go buy a scrapped battery at the junkyard and connect it up in your trunk, and it works way better because a battery delivers the power of 200++ capacitors.

It is funny how many that think capacitors work... I myself belive it triggers a "placebo effect"...


The easyest, and best way to improve it is better battery with lower inner ressistance (E) so it can deliver bigger discharges, and improve connections...

Edit: Soo, Bigger dynamo and battery is the way to go if you want to stop the flickering because when the lights flicker it is because your voltage dropps when the sub "suck the most" and the alternator cant keep the voltage up so it draws from the battery as well.

Haha, I guess electronics work by magic. All those capacitors inside everything from your TV to your cell phone must be TOTALLY useless.

I had to put decoupling capacitors on my sequential turn signal to make it work right. The cmos chips were too sensitive for the jitter caused by the 555 timer, adding a capacitor to the power supply fixed this. But Im sure it was because of magic and not because a capacitor is perhaps the most useful electronic component ever manufactured.(google RC, resistor-capacitor circuit)

A capacitor doesnt need to supply power for longer than even a few microseconds. When the amplitude of the music goes high, the capacitor drains, when the amplitude goes low or the wave crosses zero, the capacitor recharges. It does this hundreds to thousands of times a second, it is a decoupling capacitor and it smooths out the ripple from the power supply.

Adding a battery to the trunk is a stupid idea. Youve added 40lbs of unnecessary weight, you need a sophisticated electronic relay to keep it from supplying power back to the main battery or else you need to run a 0 or 2 gauge wire all the way to the trunk. Because when you hit the starter, its going to try to draw amperage from both batteries, and the 6-10 gauge wire running to the trunk isnt large enough and will get toasted.
The sulfur fumes from the battery are toxic, and youve now placed a battery inside the passenger compartment. The hydrogen fumes are explosive, and the trunk is not as well ventilated as the engine compartment. Youve also got a half gallon of battery acid in your trunk that can possibly spill.
A battery also cost money
If you use a bad battery it will kill the alternator and main battery in the engine compartment.



Need I go on?
