I must say, driving that car with MJ cranked up is even wierder than usual. I had people following me in formation behind, and people coming up alongside and giving me the thumbs up. I even got requests
I wanted to take a vid with my camera, but it ran out of battery! Typical!!!
Any way the sound system specs are:
- 1x 2x150W Response amp.
- 2x 120W cheapo party speakers (8 ohms)
- 1x Marine 12V (110Ah) battery that is still not flat after about 2hrs of
- powering the above at full volume
- Some 4 gauge cable for carrying 30A to the amp, and speaker cable
- A 120A circuitbreaker with built in voltage display so I could keep an eye on the power.
- Laptop with winamp for supply the tunes
- Car battery + alternator as backup
I wasn't sure if the marine battery would hold out for 3 hours, but it did. But then again, I probably wasn't actually doing the full 240 W because I was using 8 ohm speakers instead of 4 (permitted by the amp). Initially I planned to run them in parallel in bridged mono configuration, but it turned out to be loud enough in stereo.
But this gives me a very bad idea.... it means I can buy another pair of speakers and run each pair in parallel off the same amp.
Some interesting observations:
- Was nice to see the batt voltage slump to 11.7 during bass beats and then back up to 12.0
- Switching over to the car battery, the alternator was able to maintain 13.1 - 13.4 V driving at night with the stereo cranked to full volume.
- A mini roof can support 2 20kg (?) speakers weight. It dented in a bit to be flat, but popped out when I took the speakers off
This car never stops amazing...
Buhaha....
Edit: A had a heart attack when I first rocked up to the place. I switched the jumper leads from the car batt to the marine batt, but forgot to watch the polarization.

I freaked thinking I'd blown my shiny new amp and I'd have to use my pissy 4x50. Luckily it just blew a 25A fuse and I brought spares. I put the I in idiotproof systems.
Edit2: Reformatted amp specs, theres only 1 amp.
