So a brief update of progress, I have moved the tweeters slightly so they are more above the centre of the mids, it’s made the image more stable and the left and right are nicer now, it’s almost at the point when I’d put it into a competition and have my head healed high sound wise, all I need to do now is finish my dash pods and sort the boot... allegedly we may have some shows for the first time in August/September of some form...
the ground zero subwoofer is to be replaced with a Dayton audio RSS390HF which has very low inductance and also three shorting rings in the motor to lower distortion it will also be amplified by an alpine PDX-M6 which should be plenty (did a guy who once had a 164db car just say that????)
the next step I did was I bought a 3D printer... and designed some cups for my flangeless tweeters, basically a 60mm od cup with an angled flange to let me fix them up, I can also adjust the angle to toe them in by a tweak on the design in fusion360 and keep adjusting angles until I’m happy 5 degrees at a time once I’m close with 10 degree steps... it’s a simple adjustment in the pc and reprint... sounds simple but for strength I have them printing pretty decent quality... so it’s 3hrs a cup, but I set it going, check the first layer and then leave it overnight to do its thing... I also knocked up a design for a mega fuse holder which is now on its second design... and I will also be 3D printing some clear wedges for under the pods on the dash as due to how they fit I can’t actually make them to the part of the dash where it drops down as it also has to fit under the screen and slide in from the rear of the car at the same time which could be a bit tricky... so I figured some back lit wedges in Clear pla would look cool when printed up
