Jessica Posted July 15, 2013 Report Share Posted July 15, 2013 I'm not sure what that is skulls, cant read it. But, I belive you figure about 50% duty cycle on "D" amps, so two 90amp fuses on music should be around 90amps. 4ga is good to 140amps. I agree though, bigger wire would be better. Run some 1/0 to a distro block and 4ga to each amp. But you have one amp wired to 1ohm and the other to 2ohm. That amp should do the same power at 1ohm as it does at 2ohm. Suppose to do 900 watts at 2ohms and 1ohm. Rest in peace, walled 87 accord build log 03' Corolla build with AA Mayhem inside. My super random youtube channel and terrible camera work.

(i used sonic electronix wiring guide on youtube for that) You cant wire two d4 subs to 2 ohms. edit: on your amp, both + and - are the same output. It's just for convienience that there is two of them. You cant bridge the amp, it a mono amp. So if each d4 is wired to 2ohm, then the amp will see 1ohm. Makes me wonder exactly how the 2ohm subs are wired if maybe the other amp might be seeing .5 ohms. Rest in peace, walled 87 accord build log 03' Corolla build with AA Mayhem inside.

(i used sonic electronix wiring guide on youtube for that) You cant wire two d4 subs to 2 ohms. no offense but i have said this now for the third time, sonic electronix shows how to wire ONE 4ohm sub to 2 ohms, SO i wired both separately(NOT TOGETHER) so they both have a 2ohm load. i already knew i couldnt wire it to two Link to comment Share on other sites More sharing options...
Guest Posted July 15, 2013 Report Share Posted July 15, 2013 i'd start off by running actual 0 gauge wire from the front batt to the rear batts (and wire rear batts together with 0 gauge as well). you are probably risking a lot of shit with that single 4 gauge charge line handling EVERYTHING by itself. everything meaning charging the rear two batteries AND having to supply 2 additional amps with current.

dcornelius39 Posted July 15, 2013 Author Report Share Posted July 15, 2013 what are the d2 subs wired to? they are still wired how kicker sent them to me, so i expect it to be 2 ohms. i havent taken them out of the box they came in yet, just waiting for my custom box to be built until i do that.

Guest Posted July 15, 2013 Report Share Posted July 15, 2013 which fuse is it popping? the charge line running from the front batt to the rear batt? or the line going to the amp itself? 0 gauge is expensive? man you're in the wrong hobby if you think that $3 a foot wire is expensive.
