im not too sure if this has been done on here before but whats everyones view on taking out the spare wheel and putting a sub in that space?, this way i pretty much still have all of my boot space left.
I have a boot build with a false floor and sub in the spare wheel well. I like it, its well made (bought it second hand off here) and although its not the loudest it works for me.
I built mine myself out of mdf, my carpentry skills are crap lol, the floor was easy but the box came out pissed, nothing abit of sealent didnt fix mind. is your box sealed or ported? i bulit mine sealed at 1st and then ported it using a guide on the net, the sound quality and bass is much better now.
You would be better off with a standard sealed box. Problem with sub on the floor it's easy to damage. I have a decent sub in the forsale section of you're interested. And an amp to power it.
182 doesnt have a spare anyway, and those owners seem to cope.
The problem is that the RAC will rescue a 182 as it didn't leave the factory with a spare. They [read: all recovery companies] have been less than interested in people who have removed their spare wheels "unnecessarily".
