Can I do this?

[CPHILHOWER]

I am wondering if I can do this? I have a RockFord BD500 sub amp. Running 2 12" Dayton Loudspeaker DSQ 12.4 in parallel. 2 ohm. Was told that I could run a third in parallel as long as I used them all in a Sealed box. Currently using two in a seled box. Obcon is supposed to make a box that should fit in the back of my Escape.
Thanks

thatll put an 1.33 ohm load on that amp...BAD IDEA
i love rockford fosgate...their amps are not made to be run under 2 ohms

One of the "Techs" at RF told me I could as long as I kept them in a sealed box. Something about the box design increasing the Ohm's. I would have to assume it is because the heat from the sub has nowhere to dissipate. Either that or the woofer becomes loaded.

[sntnsupermen131]

he told you the box design could change the ohm load?
or did i misunderstand you
hes full of s*** if he told you that
i had a bd1000 running at 2 ohms and it overheated and **** the fan
i would never put one at 1.33 and ill be the first one on this site to tell you that rockford fosgate is great...

i install plenty of rockfords and i can tell you they wont handle the load maybe 13 years ago they maybe would have but not now..
kind of depressing that there are not a lot of new amps that can handle below 2ohms.. man when i first started in car audio it was all about how far you can get your amp to go...
orion HCCA red's man what a heater that was...1/4 ohm stable alternator destroyer
Lanzars 50 watt cheater amp that would do an easy 1500 watts..for $1500..
any ways back to the present. you can still find the orions on ebay, thought about getting one again but dont think i want to give up the space or money to strap the load on one of those puppies:D

Yup, Lanzar's Opti 50c was rated at 25 watts X2 @ 4 ohms but would go down to 1/4 ohm stereo and 1/2 ohm mono stable putting out between 800-1000 watts. There is a shop about an hour from here that still has one of those amps... he wants $699 for it, and it's like 10 years old! Oh the glory days of the bad ass amps.

run a rockford at 1.33 ohms and u'll be SOL buying a new amp in a day or two.

they're built to be 'clean', efficient, and small... and they do that. but not much else.

Good thing I asked. Mayve I should look into a Tri-Sub box made by MTX. Three 6000 series wired 2 ohm.
Thanks

mtx tri boxes are wired at 4 ohms.... they're three 12 ohm thunder 6000's wired in parallel for 4 ohms.

if you did three 8 ohm or DVC 4 ohm 6k's you'd be at 2.66 ohms.

[CPHILHOWER]

MTX does make a Tri-Sub box wired 2ohm.

what are they six ohm subs???

[CPHILHOWER]

I saw the box on Crutchfields website. Not sure. Maybe 12ohm DVC?

i know that they have the 4500's available in a 2 ohm config but to the best of my knowledge (and the mtx website) the 6000's are only 4 ohm config... possibably a crutchfield special, something that they pieced together themselves...

[CPHILHOWER]

I checked the website. Model # T610X3D. Three DVC 6000A wired 2 ohm.

must be a crutchfield special, cause it doesn't exist according to the mtx website...
