Hi...Looking for an audio installer to fit a small active sub. I live in Burnham-on-Sea. I would fit it myself but I just haven't found the time with also doing work on my van. Anyone that can suggest a decent installer that would come to me?

Best of going to an audio company to do such a thing.
It would need to be a custom enclosure as there's not really any space for a sub box so to speak.
