How are your grounds?

for the car or the stereo?

regardless i think their're both fine, i had a problem with the neg awhile back but i put a new clamp from the wire to the bat and its fine now

Not quite sure how the grounds are on the sn-95's but foxes need to have grounds redone with better wire and more grounds added. Just a thought.

like the one from the bat to the frame?

battery - frame, engine block -battery, engine block- frame, make sure the alternator is getting a good ground. wouldn't hurt to go from one of the bolt s that hold the alt to the frame or battery.

alright i guess it wouldnt hurt anything to just do all new wires since they are 15 years old

There is a small silver cylindrical object next to your distributor which is supposed to filter out the noise from the coil. Make sure that is still connected. It's not uncommon to have the wire fall out of it.
