Firstly, I would hope you are really talking woofer speakers, not subwoofers
which are for use below 60hz which is not recorded on tapes.  The use of
'subwoofer' instead of 'woofer' usually means low quality.  There is no
such thing as a small subwoofer.

Where are these components located?
Ignition noise enters very low level (microvolt) signal paths like radio tuners,
and tape preamplifiers, not 1 volt level items like amplifiers.   
Under what circumstances are you hearing ignition noise?
