      Hi Pf Guru's.
      I was after some coolant for my 1948 HQ Falcon and the guy at Super-repco told me they only have Green or Red Coolant but my car is Blue.
      What should i do??
      Thanks in advance. Forg.

Use ohms law. set your headunit to the max voltage you use (may not be full max, often head units distort and clip before max), now set your meter to AC voltage, and without a speaker connected - up the gain on the amp to suit. https://www.youtube.com/watch?v=gg2gl-fz2Qc
            i should know this but...

            internal DAC's in headunits

            if you're using line out on a headunit, are you bypassing the internal amp, and if so, do you still get distortion/clipping when you have it cranked?

              Yeah you can. There is still a 'line driver' circuit to feed the RCA out. It hopefully wont be anywhere as significant as the internal amp.

                Ok, again demonstrating my car audio noobness, but I was initially looking at installing a 4 channel amp to power my speaker setup. But would it be just as good if I were to get 2 x 2-channel amps. One for the rear and one for the front speakers (obviously)?

                I'm thinking this will avoid me running new cables and allow me to use my existing speaker cable (and also make for a neater install) and just install thicker cabling for the final run from the two amps to their associated speakers.

                  I don't understand how that setup means less wiring.

                    Long story short, is $4800 excessive for supplying and replacing a broken 6spd auto box on a 2010 Holden Epica?

                      $4800 is an excessive price to pay for a complete Holden Epica
                      If in doubt power out

                            Anyway, it's kind of a useless point.

                            overpowering speakers is LESS likely to cause damage than underpowering them.

                            as the speaker moves it pumps air through the voice coil, meaning it's cooling itself. Extra power isn't so bad. (not saying you can't overpower a speaker)
                            Now if underpowered, and you're pushing it hard to get the volume you want, you risk clipping, when clipping the amp is essentially a DC power source and the speaker isn't moving = no air flow = no cooling = cooks the voice coil = dead speaker.
                            No, having a crossover means it's still a 4 ohm load. (assuming decent crossover design)

                            From a 50W amp you could be driving the speakers with 50W of bass only, which will all go to the woofer, or 50W of treble only which apart from making your ears bleed will all go through the tweeter. So both speakers should be comfortable with accepting 50W.

                            Don't disagree with the rest though, make sure it is a clean signal not a square wave.

                                The AN "dash" number is the number of 16ths of an inch the internal diameter is - so -4 is 1/4", -8 is 1/2", -12 is 3/4"... so ~10mm is -6
