They are starting to get buzzy, especially on the passenger side. The tweeters also have a decent amount of noise in them right now. No matter what, I'll be leaving the McIntosh headunit in because anything else will look out of place in this car.
And, like I said, it looks like rust is starting to form on the undercarriage. I'm not sure if it has been there or if that happened after moving to Florida last year, but I definitely want to get that taken care of.
I'll probably get a set of jack stands and a hydraulic lift because those are things that will be very useful down the line as well for things like oil changes and other repairs.
with this remember that the head unit and the amp under the front passenger seat go together.
I wonder if your wires are the problem. and should be traced from each speaker to the amp before buying anything.
rust underneath,... no pics yet.
but: using a copper wire brush on a power drill is pretty good:
it removes the rust and any black rubbery undercoating but leaves the good grey primer on the good body were there is good body. and then you repaint and reseal what you got. (I did some of this in the past few months)
based on the pics you have posted so far, I would think what you are calling rust, people north of the mason dixon line would consider NOTHING. important to get after, but
when you got fist sized holes in the quarter panels over the rear wheels,...and in the rear door frame. = that is RUST.
where was the car from originally? how long was it there before it got to sunny florida.?
other things to add to the maint. list if not changed recently:
a OEM rad cap, a OEM thermostat, and NGK double platinum spark plugs.
plenty of good EZ30D, McIntosh, and gen2 rust discussion here though.
