    I thought the factory enclosures could possibly benefit from a front to back cross-brace. Will you reinforce the area you cut out?
    Looks great.

    Sorry xschop for the late reply as I didn't notice this message 8 years ago :# , sda 's would definitely benefit from front-rear bracing.I didn't reinforce this cut out but the front and rear baffles won't resonate at the same frequency, thats for sure.

    These could do with your internal front to rear baffle brace and the Shaaaaken test :)

    Just copy my CRS+ dowel diagram B) Shakin' over here boss.

    You should copy the back-chambered RDO's too.

    You should also copy @Gardenstater's foam frame mod as well. Get the shout out.

    Too right, mate! Love a bit of Foreigner. Head Games is an absolute ripper, Urgent goes off, and Cold as Ice is a bloody cracker of a track
