What do u think is happening? All of a sudden now my amp gets hot, and goes into thermo mode. ALL i did was change the box from 2.5 cubic feet 32hz to 1.5 cubic feet 44hz, and the smoke is crazy and the amp got hot. It is 2dbs louder, but it wasnt even ran parelle it was in series to a 2ohm load. There is a comp tomorrow, and Im gonna burp it at .5 hope I dont fry everything.

You could be getting less impedence rise with the smaller box so the woofer is getting more power?

sounds too me you made ur new box alot more effecient which is good. i would rest ur gains and try another run...

I guess I should have changed my signature. I am only running 1 phd5000 at 2ohms. The only time I ran the two was for a burp, just to see if I could. The two phd5000 both have 2 gauge going in power, negative, 12 gauge remote, and RCAs, but only one has wires going to the sub. The other 1 is strickly for comps or emergencies. As far as playing songs below my vehicle frequency, well my car use to peak at 46hz, with the old box and now its more like ~56hz. So that might be the reason. It just seems my amp got a boost, a major boost. I went from hitting 147dbs to 150dbs (in the dash on my epic160) for burps, just by changing the box. But at a big show last night I only hit 142.4 in SB1. There was a bit of smoke, and volume only at 20, when I use to have it at 45 and no smoke. I was scared to crank it cuz I was scared to blow my woofer. I did hit 147.3dbs on the termlab, but then I turned it down and ended with a 142.4dbs. SB1 you have to run for 30 seconds and they take the average. I still won 1st and got my trophy. If there was more people hitting higher numbers, I would have let it rip. I used the USACi CD number 5. I never even needed to drop it down to .5oms. I knew the epic160 was off a bit, but not by +4 dbs. AS far as running 0gauge, man that is sooooo expensive. If I had an extra $70 laying around, Id get a line driver. When I get my other soloX, I'll pick up my o gauge, and a line driver, then I'll be able to use both of my phd5000s. SB1 scores this year are at 157dbs, so thats way out of my league.

I agree, you should do multiple runs of 0 guage. When you do upgrade to 0 leave the run of 2 guage in also. The more wire the better. Right now in my car I have 2 runs of 0 and also 2 runs of 4. The idea is to get as much wire to transfer current to the amps as possible. Also try running wire from the negative post to the rear to the amps too. This will help to stiffen the voltage and keep the current flowing consistently to the amps.

Smaller box lower impedance rise and higher frequency. Need to change song that plays higher bass notes.

how is 0 gauge gonna help me when all I can run into my amps is 2 gauge? if I run 2 runs of two gauge 1 for each amp that should be perfect. the 0 then into 2 gauge will creat a funnel effect. u can only get the power that the 2 gauge can put into the amp, so 0 will only creat like some sort of choke hold between the 0 and 2 gauge, wont it? Im no physics major, but thats how I see it. If I run 10 strans of 0 gauge, but only run an 8 gauge wire into my amp, I only draw what the 8 gauge can handle correct?
Anyway, I know that has nothing to do with the subwoofer smoking. That was what the original question was. But thanks anyways.

you want the smallest voltage drop over the wire as possible. the longer the run, the more resistance for a given amperage. Running 200A of current through a 0ga wire at 20ft can give you a 0.5volt drop. Adding a 2ga power could reduce the drop to about 0.3v on the same current draw. Your amp is possibly drawing over 300A.
