i finally got time to look into the subs to see why they wernt working , I tested the amp and it appeared to be giving out a signal so I stripped the back out , pulled the connector and had a signal upto that point , so I removed the subs to find they werent even connected , plugged back in I have sub base again , well one channel isn't producing a signal but the other 3 are so that will do for now , cant think why someone would disconnect them entirely , very odd

Probably carried a dog in the boot?
Stupidly loud bass from ours so dog now has the back seat with a waterproof cover on it.

yeah it was a bit doggyfied in the boot area when I got it pal , I guess sub base would irritate a dogs hearing quite abit too
