Subwoofer issues Options

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?

for the flickering, your alternator cannot recharge the battery or maintain itself rather faster than your sub bass hits. you fix it by getting a good battery like optima, get a higher amp alternator, a capacitor, and upgrade the big three wires.

He is correct, if you're having power strains from your system you should do the big three, then the alternator. You can take your alternator to a rebuild shop to have them beef it up. After that if you still had power problems you can add some dry cell batteries like these or or this, while running bigger gauge copper wire to your trunk. Batteries though are not needed for most people, even when the think they are needed.

Also where/how did you ground your amp in the trunk? The best way(that I know) is to get yourself one of these to remove all paint around your ground point. Check the ohms at said location with a DMM, the lower the better. Good locations are the strut bolts, or any spot that's not spot welded and is more in connection to the frame. But this is all based on information that I've read/heard over the last few years since I got into car audio, which some may have different view points/suggestions.
