Got a new BM. Need a good spot in North London/Hertfordshire area who can do a full car sound system upgrade, supply install etc. Do all BMWs have such crap stock sound systems - can't believe how bad it is? Especially going from my old Volvo which had a beastly system.

Got a quote for 4.5k from Impulse in Watford. What a joke guy must think we all made of money. I have a budget of about 1.5k
