I have a Directed 2400D and i have it hooked up to my DD9515 running at 3ohms. My DD has dual 1.5ohm voice coils. will the amp take a .75ohm load if i run the coils in parallel?

Only one way to find out. Hopefully it has a good protection circuit in case it can't handle impedences that low.

i think the amp might handle it, get some cooling fans

Just sit in the trunk and blow on it, and it will be fine.

lol i hooked it up with a .75ohm load. WOW it pushes my DD9515 alot more now. if i get cooling fans do i just put them by the amp. also if the amp is 1400watts at 4ohms and 2400watts at 2ohms does that mean it is 3400watts at 1ohm or not necisarly?

No, it doesn't mean that at all. It isn't just a simple ratio. There are plenty of other factors involved.

And just be careful with it. Cooling fans may help a little, but honestly if that amp can't handle a ohm load that low then the fans won't help you that much.

DO NOT attempt to street beat that amp at .75, burping only.

and when you double half the load on the amp, the output doubles, so if you were pushin 2400 @ 2, more likely arond 4900 watts, even lower than that = even more watts

It will only reach this if u have an adequete chargin system

you should have bigger than an 80 a fuse when running 2400 watts.

here is a lil list to go by. but this is the MAX the fuse can take at these...

Wire Gauge Recommended
Maximum Fuse Size
00 awg 400 amps
0 awg 325 amps
1 awg 250 amps
2 awg 200 amps
4 awg 125 amps
6 awg 80 amps
8 awg 50 amps
10 awg 30 amps
12 awg 20 amps
14 awg 15 amps
16 awg 7.5 amps

and you need to take into account wire length, but that gives you a good idea :-)

you could try getting a diff amp, but that amp would still be fine burping. depends on how much output you want or need
