[QUOTE="taloola, post: 251810, member: 548690"] Thank you both for your reply, I tried making a new earth connection directly to the bodywork near to the amp, but it made no difference at all. The system sounds great when i have the key turned to position 1 only. I have been told the base tube is a good make, although the manufactures may now have gone out of business. The amp is a 4 channel amp 4x75w variable gain s/n ratio more than 85db frequency 15-30khz suitable for 4 ohm speakers, I have 4 speakers the two at the back are JBLGTO522 4 ohm amp range 5-150 w per channnel, F.R. 55hz-22khz sensitivity 90 DB. The two speakers i dont know much about but i think they are about 80-90watts. The only thing i can think now is either the system is incompatible? could i have got one of the connections to the speaker wrong. Or is the built in suppressor to the coil faulty (volvo 440 1992) or is the engine earth bad, or panels badly earthed? Im not sure what to try next, hope you can help [/QUOTE]
