What are the possible ohm loads with Daul 1.5ohm coils?

[grillman6000 10+ year member]

I'm looking @ an audioque hd3 sub.....

the come in either dual 1.5's, dual 2's, or dual 4's.....

I already looked on the Rockford site, and with a single sub with dual 2's or 4's...there isn't a way shown to a .5ohm load.

I want to wire my amp to a .5ohm load....

which sub load should I get? On Rockford site dual 1.5's aren't an option....so thats why I made this topic....

So, I was wondering if dual 1.5's cood go to .5ohm ?

THANKS!

also, if possible....can someone draw me up a quick wiring diagram on like paint or something if this is possible....

Dual 1.5 in paralell will yeild a .75 ohm load.

Can't get to 0.5 ohms...

with 2 subs...

Off the top of my head you could either get

0.375 or 1.5 ohms or 6 ohms

One sub...

.75 or 3

yeah....

with one sub...i need to get .5 ohms.....amp: Sundown SAZ-1500D

what ohm load would the sub have to be for me to get to .5ohm ? dual 1's?

 

[ravendarat 10+ year member]

Yep Dual One's. Why do you HAVE to get to one ohm, looking for an easy way to raise your thd or what?

 

[grillman6000 10+ year member]

no...because the amp is rated @ 1500w @ 1ohm, right.

well, sundown's warranty covers .5ohm use....basically saying, it's ok to use the amp @ .5 ohm.

well, I want to use it @ .5ohm, giving almost 2000w.

But, I am new and I dont know what coil ohm loads will get me down to .5ohm.

So, for me to get to a .5ohm load with one sub and one amp, I will need a dual 1ohm sub? Correct?

Yes.

You won't get 2000 watts out of that amp running it at .5 ohm, especially in a daily install. Impedence rise is a b*tch.

Yes, but even if their warrenty covers it running down to .5 ohms I would not do it. That is generally going to yield an increase in distortion that is not going to be what you want for daily driving, and if it does 1500 at one ohm, but only 2000 at a half ohm than the difference in power between .75 and .5 at that level is going to be miniscule in my opinion and not worth worrying about.

 

[grillman6000 10+ year member]

Yes.

ok. kool. now is there anybody who could PLEASE draw me up a wiring diagram for me so i will know how to wire it all up when it arrives?

 

[ravendarat 10+ year member]

positives off each coil to the positive output on the amp, negatives off both coils to the negative output on the amp. Done.

 

[grillman6000 10+ year member]

So, should I stay away from that amp then? I was also looking @ the BXi 2006D....good amp?

like 1900w @ 1ohm....daily

plus to plus

minus to minus

Im sure the amp is fine. Its the ussage thats the issue. I would never run any amp for street use at .5 ohms. I run my amp for COMPETITION at half ohm but its for SPL and I could not give a flying **** about distortion. Even one ohm is low but probally tollerable and if you are trying to get that kinda power out of an amp and you dont want to pay out your *** for it than the amp you are looking at is probally not a bad way to go.

 

[grillman6000 10+ year member]

ok...because I need at least 2000w to power the HD3-12 for daily....

would you happen to have any amp suggestions.....?
