thing I used to do for comp cars was have the second battery isolate with the key off. that way you could run the stereo into the ground and still start the car.

if you go this route make both batteries the same size.

Hey

Chris Rogers i may be going down that path later on, next year sometime :) thanks for that advice i will keep it in mind

I will probably go for the optima yellow top D34 and im unsure on the 'cap' issue as there are mixed opinions on this thread...

get the battery first...

a cap is like a big power storage tank.

when a big bass note hits and it uses lots of power, the cap is there to make sure there is no misses, ie make sure there is power ready for the next bass note so you dont get a loud bass note, then the next one is soft.

you need the battery to actually fill the cap up with power, if you dont have a battery big enough to do that then the cap will just drain more power from the battery and your system wont work well at all...plus you'll get dimming lights etc etc

get the battery...

i have seen 100s of very high power systems running a D34 with no cap the lights might dim a bit, but the system wont miss a beat

    • Bit of a pity we don't have good images of the back/front of the PCB ~ that said, I found a YT vid of a teardown to replace dicky clock switches, and got enough of a glimpse to realize this PCB is the front-end to a connected to what I'll call PCBA, and as such this is all digital on this PCB..ergo, battery voltage probably doesn't make an appearance here ; that is, I'd expect them to do something on PCBA wrt power conditioning for the adjustment/display/switch PCB.... ....given what's transpired..ie; some permutation of 12vdc on a 5vdc with or without correct polarity...would explain why the zener said "no" and exploded. The transistor Q5 (M33) is likely to be a digital switching transistor...that is, package has builtin bias resistors to ensure it saturates as soon as base threshold voltage is reached (minimal rise/fall time)....and wrt the question 'what else could've fried?' ....well, I know there's an MCU on this board (display, I/O at a guess), and you hope they isolated it from this scenario...I got my crayons out, it looks a bit like this...   ...not a lot to see, or rather, everything you'd like to see disappears down a via to the other side...base drive for the transistor comes from somewhere else, what this transistor is switching is somewhere else...but the zener circuit is exclusive to all this ~ it's providing a set voltage (current limited by the 1K3 resistor R19)...and disappears somewhere else down the via I marked V out ; if the errant voltage 'jumped' the diode in the millisecond before it exploded, whatever that V out via feeds may have seen a spike... ....I'll just imagine that Q5 was switched off at the time, thus no damage should've been done....but whatever that zener feeds has to be checked...

    • I think Fitmit had some, have a look on there (theyre Australian as well)
    • Hah, fair enough! But if you learn with this one you can drive any other OEM manual. No modern luxury features like auto rev-matching or hillstart assist to give you a false sense of confidence. And a heavy car with not that much torque so it stalls easily. 
    • Actually, I'd say all three are the automatic option. Just the different trim levels. The manual would be RSFS, no?
