Cant decide on what Impedance i want for the HDC318s , they will be powered by 2 Rockford Fosgate T1500-BDcp. Cant decide! Help! =]

d1 so you can wire those amps @2ohms. I would not attempt to run fosgate under the rated impedance.

i agree!!

But if i get D1s how would i have them wire to 2ohms? Wouldnt i want D2s if I want 2ohms?

Its called wiring in series. D2 would only let you wire at 1 or 4, a D1 allows you to wire to .5 and 2

You want 2, so get a D1 and look up how to wire in series, many diagrams available.

Rockford Fosgate® - RFTECH Support

When i put the options for 2 subwoofers and Dual Voice Coils at 2ohms, it says it will give me 2ohms or .5ohms.

Am i missing something here?

In the first instance you are talking about one sub. the second you are talking about 2 subs. that's the diff right there.

i gotcha, just worked 13 hours after 4 hours of sleep.

That RF calculator is thinking you are wiring both subs to one amp. use it for one sub, since one sub will be hooked up to one amp. It's the load the amp is seeing, not across the board!

With that being said, what would you recommend i go for? a Pair of D1s or a Pair of D2s?

are u straping the amps or running one sub per amp?

 

[goingdef 10+ year member]

Same amp I got I would run it at 2ohms so it raises efficientcy and you still get roughly the same power so I would go with d1s on each amp at 2 ohms.

What would be the best bet? This is my first big build so im new at this so i want the best way possible

well i dont know the amps are they strapable? if they are, and 2ohm stable each then they will be 4ohm staped.

It has a pass through option (RCA) on the amp. does that mean its strapable?
