Cheers princy, good read that! I'm thinking 25% covering around wheel arches, roof, under rear seats, doors and boot floor of whatever I decide to use. Like the guy says there is a lot of different noise types and aims. I will be happy with less road noise, better sounding sound system and get rid of rattles.
My car at the moment is so noisy with trim at the moment at low rpm I cruise in 4th a lot to keep the revs up. Obviously not when the speed gets up 5th is ok. I have new doors to put on in 8 weeks and I have to Change the glass too so ill be able to get right in there. Also look for some good component speakers and mount the tweeters in the mirror triangles. I will eventually get around to a better head unit, small amp and maybe one of those micro subs that can fit under the front seats as I need my boot space. I don't need ultra deep bass as I listen to mainly to rock/metal so just a nice punch for the bass drum
