Test results will be up tonite.

2 hc2400s in the back and 2 12" SX subs. Not changing anything except doing a direct swap at 1 ohm stereo, then .5 ohm mono.

Heres a few comparison shots

wait so you're going to compare power output of the dog and the hifonics amp? WIKED! lemme know which one does more better:D.

So far

At 1 ohm stereo, colossus is down by 1.2 dbs
At .5 ohm mono, it is down by .7 dbs

Gonna try some more tricks though.

what's the rated rms that both of these should put out at those #'s?? i know i could look up the colossus but i figured you're on and well you dont have to look it up:p:

colossus is 3200w mono at 2 ohm, I think 14.4v

VFLs are 2000w at 1 ohm at 12v

whats the actual nominal dcr for these tests?

I will check that out when everything is done

Heres an interesting note...

I went down 2 freqs from what I burp at with the VFLs, and the score just went up

Now I am .2 down from the VFLs

Im gonna tinker with the settings now.


I guess you can say this is a very strong amp from being almost as strong, if not as strong, as 2 vfls.

are these modded vfls

btnhfan

No

They do not need to be modded for higher voltage or lower impedence.

The VFLS really shine at 16v+

so vfls do 2kilowatts at 12v out of the box? hmmmm

VFLs are 2000w at 1 ohm at 12v

is that 2kw per vfl or what?? i used to know those amps well but that was when they first came out and people made such a big deal about them.

Yes 2kw per amp

I cant find my dmm, but I believe the coils on the SXs are something like 2.6, Im not exactly sure.

If thats the case, then its .65 dcr, not .5
And 1.3 dcr

wow that is impressive i think. what kind of voltage are we talking?? obviously you're a noob so i'm not sure if you'll know this:p:. thanks for the comparison though man i'm sure a few peeps were wondering about the colossus.

I didnt have my dmm for the colossus test, but for the VFLs, it was dropping from 14.7 to 11v

I would assume it is about the same.

is the colossus regulated or unregulated??

i just wanna know if the vfls would do 2kw out of the box at 12v

then run a search....there isnt any mods....so if it'll do 2k, it does it out of the box ;)

i did do a search and i asked cuz nothing came up.

Yes they will

No modding is required.


Im going to mess around with this amp some more tomorrow. Seems like I have some untapped power left to get out of it. So far I am very pleased

Good job snova :)

what would they do at 1ohm with ~13v

bigbassman

150.1's do 1500-1650 watts @ 1 ohm with 12 volts

150.1's max out @ 2750-2850 watts @ .25-.3 ohm with 12 volts, you may have to roll the volume..

they'll daily drive @ .5 with 12v, generally...

we've used them extensively up here... in vehicles running anywhere from 1, to 8 of em.. 12v, and 16v
