Recently found a clean 99 SVT. I don't do a whole lot for changes, I love it stock. But I am working on a stereo installation. I completed step one a couple weeks ago. An old school Sony component set in the rear doors. They are just the regular Xplod speakers from around 2003 or so I think. Brand new in the box from ebay for less than $50. They should match up nicely with the same era Sony mobileES component set I have for the front doors. Both sets are 5 1/4". A few days later I put in my head unit for the moment a Sony CDX-5750. This was step 2 and may change - I want to stay sort of Old School. Just running through the lame factory amp for now because an amp install is coming soon. Picked up a clean old Alpine MRV-F450 5 channel. Step 3 was last weekend when I ran 4 ga. power and remote turn on to the trunk. I haven't decided what is next and don't know when I'll get some free time... it'll either be installing the front speakers or the amp. Later I'll be installing a modest subwoofer setup.
