I am happy with the 'highs'(touring )but want a little more bottom but don't want a box ,amp ect.And would like to be able to remove easily,anybody have or has had a powered bazooka?

Have a look at the mazda 5 forum on mpvclub.com. Someon build an 8 inch sub into the right side cubby behind the third row.

Thanks I will have a look!really don't want to cut and be able to remove easily,thats why I was thinking powered tube!

I installed a Bazooka EL (powered) a couple of weekends ago. Pretty much straightforward if you've done stereo DIY's before. I had to use the high-level as I still have the stock HU.
The sub itself is still in a temp location as I still have to buy the cargo mat and will figure out then how and where to mount the straps. Until then, the sub is temporarily mounted with industrial Velcro. ;)
