ultimate 6x9s
I've attached a photo of my parcel shelf.
I notice that you mentioned about perhaps needing a more sturday parcel shelf in your car. This will improve bass even more greatly.
It's very difficult to get a flat parcel shelf to fit the almera correctly and so i finished off making mine with a box underneath the shelf, separated into a pair of chambers, one for each speaker.
The 6x9s now sound as good as my £500 speakers in my house, running through an alright amplifier.
if you want some copies of my drawings then i could email them in due course. I haven't seen a shelf quite like this, there's a few unique points to it.
Hope you enjoy my work, The finishing touches to the boot will follow.
Might I add that this modification erradicated the need for my 12" sub.
Also, the slope at the front of the box is at the same angle as the back seats and helps the thing hold in tightly.
