It's got a JVC head unit, no sub (gas tank), not sure of brand of amp and I'm not home to check. Infinity splits which I just noticed a few days ago has a crack in one of the speaker cones. Bit disappointing.
I think it was originally a SLX. What i did was buy it as a 6 cyl and bought a smashed SL 253 for all the running gear. So it has the V8 engine, V8 gearbox, V8 diff which had disk brake rear end. That's also why I have so many spares from the other car. Don't have any pics of the engine bay but can get them when I'm home on the weekend.
