August 8, 201312 yr ISO loaded being louder on less power has me vexed. I'm terribly vexed.I don't know if that's true. really interesting results. Still have to tune the non-iso configuration. actually, with am isobaric config, it's easier to bottom out the speakers because you have the equivalent of one speaker in twice the box.
August 8, 201312 yr Author adrian , have you already soldered te speakerwire to the speaker connectors ? To my shame, I did not solder the connections, YET. Going to do it today and figure out a way to quickly connect/disconnect. What is the effect of not having them soldered? [offtopic] how close are you to Amsterdam and Eindhoven?[/offtopic]
August 8, 201312 yr Resin helped at least 0.4dB. 142.5 without ductape around the speakers (helps 0.1) and 142.6 holding the rear quarter windows. So far so good, time to resin the outside of the box. Where around the speaker is that ductape?
August 8, 201312 yr Author From the frame lip to the box, on the outside, so that it does not leak air.
August 8, 201312 yr Author Not a problem and usually even for SPL I've had mixed results. Wont hurt but can't say for sure if it will help

[offtopic] how close are you to Amsterdam and Eindhoven?[/offtopic]I'm at a 3/4 hour drive from Eindhoven (aproximatly 80Km ) , Amsterdam is about a 3 hour drive (230 km) , I'm in the most southern part of Holland . couldn't tell you what difference soldering makes , I've never wanted to do this myselve for my drivers have always been fairly expensive and not waning to remove the pushconnectors
August 9, 201312 yr Author We'll see what soldering does as soon as I clear up more time for testing This project has been very exciting so far and having 2 people work on it makes it even better. Somehow I see myself ending up deadening the roof of the Jeep, it's on the backburner and if it helps 0.5 for this project, all the better.
August 12, 201312 yr Author Bu-fucking-mmer Highest score today was 142.4 dB @ 49Hz, box in a different position and almost class legal. We blew an 80A fuse and measured 50v and 12 amps on the subs. Still holding strong, although I think we will move back to iso-loading. It's easier to tell when to stop turning the volume knob and apparently it scores better. Bracing also hurt the score, it went down to 142.1 @ 49Hz. It helps at lower frequencies but not this high. Double baffle / double bottom would probably work better than bracing.
