2 12" Alpine Type-R's and a Fosgate BD1500.1

[evilsaint 10+ year member]

I have 2 12" Alpine Type-R 4Ohm DVC subs and a Fosgate BD1500.1 amp. I have no problem hooking up the subs into a 4Ohm load, but I can't figure a way in hell of wiring them into a 2 Ohm load. Any help would be appreciated, because considering the relative simplicity of the question, I really feel like a dipsh!t not being able to figure out how to do it. //content.invisioncic.com/y282845/emoticons/confused.gif.e820e0216602db4765798ac39d28caa9.gif

You can't do it.

why is it not possible, isn't there some way to series-parallell the subs that I'm overlooking?

Nope, not possible.//content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif It's either 1 or 4 ohm.

How would I go about wiring the subs into a 1ohm load? My amp was modified to run at 1Ohm stable because it's former owner used it in SPL competition. The subs might not be able to handle it, but I could always buy two more.

If your amp was modified by someone and used in an SPL contest and he won then he should be disqualified. Have him check out the rules.

either way, how can i hook up the subs into a 1ohm load? and why is that against the rules in SPL comp?

To get a 1 ohm load you just wire all the positive+ inputs together and all the negative- inputs together. The impedance (ohms) of the speaker doesn't change, a 4ohm coil will always be 4 ohms, it's just how you wire them together that determines what ohm-load your amplifier "sees". Your subs have 2 4ohm coils each so when you wire all 4 coils in a "parallel" configuration( all +to+ and all -to-) your amp sees a 1 ohm load.//content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Because the amp has been modified to exceed the man. specs. In other words it's considered cheating. I have been at an IASCA event were someone had done the same thing. The 2nd place winner protested this and I watched as they tore the winners blazer apart only to find his amps were modified. Needless to say he went home empty handed and with a blazer full of parts to be reinstalled.
