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? --------------------  |

It could be a bad ground but its more likely to be the amp drawing too much current from the battery. This puts a lot of extra stress on the battery and alternator. What size amp do you have? A capacitor is supposed to be a fix for this issue. It acts as a second, small battery so that it takes the hit instead of your battery. However, I've heard several times that capacitors are a huge waste of money.

Ive never needed one but a capacitor is designed for delivering large amounts of current very quickly. Using a large capacitor would even out the spikes in the current. As for securing the box, what I did was drill holes through the bottom of the box into the underside of the car. I felt that 3 bolts in a triangular layout were sufficient, since it was hard to reach two corners of the box from under the car. You will want bolts about 3"- 4" long, and what I did was cut up the sole of an old pair of running shoes for the mounts. You want a chunk of rubber between the chassis and the sub box, but you also need a chunk of rubber between the box and bolt head and between the chassis and nut. If you dont add these two extra rubber pieces then vibrations will travel through the bolt. So here is the order I did starting from inside the box to the underside of the car.
