All,

Been silent, very cold - garage is a 100 year old Yankee version, no heat.....will not hold any. So, my 17yr old son and I decided to upgrade the speakers (the old ones were absent any cone material).

Found a set of KFC-4675C (kenwood) that fit the spec, integrated mid range and tweeter. Now for the low range. We decided that carving up the car and running a large alternator and battery was not for this car, we are trying to restore it to 80-90 points. So we are using a passive crossover, the original tuner with a power amp that was installed in the 80s, still works (both units are Blauplunkt). We have about 40 watts - more than enough for the size of the car.

When we rebuilt the car we installed sound deadening material in the engine bay, passenger compartment and will put it in the trunk. Amazing how quiet the car seems in the passenger compartment now.

My son had the idea to install the Subwoofer in the engine compartment, cut through the back seat - had to explain the concept of FireWall to him, we looked at a dozen other places and settled on what I think is a very elegant solution.


Our car is a '74 2.0, Silver. So it has a center console. We are installing it there!

Look at that circle, no wood showing, barely a wrinkle!
