Sub enclosure and Strobe light

[Goulburn Boy]

Just a couple of questions any help welcome

First off i have a Alpine SWS-1223D Sub with a 400rms mono block sub pionner something... Its all good except i have it jammed in a small Audioline al125 box... Does anyone know if i should build a new enclosure to put the sub in and wil it make much of a difference... If so anyone have a box design they want to share?

Secondly I have a Small strobe light that is build for a 240v is there anyways to hook it up to the boot light? or to the battery and it will work?

Thirdly i have a Pioneer deh-p4850mp Head unit and want to upgrade to something with a front aux for my ipod, Any suggestions of a head unit that comes with the same options + aux in front for around the $150 mark?

thanks

Also just an idea, would it make a differnce if i mounted the sub face down. I like the look of this, not sure if it will change anything though.
