Auto stores will have a longer bolt for the side battery terminals or
adaptor kits if needed.
Use the right size heavy duty solder lugs for the connections.

I looked up my lighter circuit and it is 8 amps -- so 8 x 12 = 96 Watts --
at 50% or so efficiency -- should handle a 45 watt radio -- but that is
pushing it to say nothing of stray noise that may be introduced and a
possible voltage drop. Also the cigarette lighter may go thru the ignition
switching.

Somehow on all my cars I find a grommet that lets me get thru the firewall
without drilling.

While I agree, I'm looking for a portable solution to use in the 'yl's
vehicle so I can run a decent rig without drilling. I figure 10-20W is
adequate (I think the 1/4 wave antenna I have allocated for this use is
only rated at 20W anyhow). In a small temporary installation like this I
think using the lighter plug is good enough.

Of course while on the topic, What's the best way to connect to today's
side terminal batteries? I'd like to go from the battery's +/- in *my*
vehicle to a small fuse block where I can tie in before coming through the
firewall. Unfortunately I don't do a lot of auto wiring and firewall
drilling!

thanks!
