im trying to maximize flow to my coils, so i bought aluminum blocks (0.75"x1.5"x3") to mount to the box. the 1/0 from the amps to be routed to the box then connect to the 8 guage from the woofers. srry my description is rough but im lookin for an opinion weather or not the aluminus blocks for speaker distribution is a good idea or not?

why 1/0ga to the speakers? how much power are you running? and what amp do you have that uses such big output wires? more points of resistance might be worse than using smaller wire

only amp that I know of that can take a 1/0g wire is the soundstream XXX amps but even they need a reducer which is another point of higher resistance

even in the testing dB Don posted of a Stetsom 7k2d the other day, he was only measuring about 60A of A/C current from the amp. 6ga would be just fine for one of those

No matter what size wire you use the impeadince rise will still be high....seems to be a NW box thing. All the greats have chased it and no 1 ever came up with a cure.
A good true 8 gauge wire is more then enough if run 1 wire per termanial at the subs.

hey Pete, I think i got us off on the wrong foot previously...my apologies dude. and in regards to your post, im pretty sure your right. i have less than 0.5ohm rise anyway, infact my amps go into protect at the end of my burp. "each amp see's 0.25ohm before rise"!
posted
Why are the amps protecting...low voltage or your ohm load ? If its at the end of a burp I would guess the voltage is droping to low HOWEVER if it's low impeadince then you may infact have a few clicks left if you can get the rise up a little more. INfact you may want longer wires to aid in that.
I would almost bet its low voltage. To be at .5 rise it must also be a very shallow box, what is the depth inside from the back of the baffel to the back wall ?

ive since done some work to this box im using, the box is now 28.5" from the back of the baffle to the back wall, the baffle is 6" thick opposed to 3" like it was. im using 18's
i was only using 6x 8v batts and they were not charged well(was using a 12v charger/ just got a 16v charger) and will be using 10 batts charged with the 2 amps

6 batterys before or after seriesing to 16 volts ? Even if it was before 3 sets of 16 volts per amp is not enough if you are trying to run the amps low imp.
Just rember a battery can only discharge so much current, even though voltage still seemed ok it may have been at it's current draw limit. Also how many runs or wire per amp for power ? I know I used 6+ and 6- per amp with my little stetsoms and they are 1 of the most effient amps built. I gained every time I added more wire. The stratge part was the voltage drop was the same but current draw was able to incress.
Thats the same theroy as your post, get the most current from point A to point B.

right now there is just the 2+ and 2- per amp, i think i may use those blocks i have to add more runs and forget about the speaker wire...and the box, well, im not sure if it will come out in one piece anymore! i guess its kinda like yours just not as deep overall.
and it was 6 seperate 8v battery's, and believe me they were so poorly charged, that i only increased 0.3db by rewiring from 1ohm to 0.25ohm and freq decreased 1Hz
