that amp doesnt do 1000 watts. it wont be stable at 2 ohms in all liklyhood. I'd look into a different amp if you havn't ordered it yet.

 

I may just end up wiring them independant. one channel per voice coil. since each channel runs 250 watts @ 4 ohms.

 

Do That. Then you can get the 500RMS out of the sub. Because each coil is 250RMS.

 

got the sub in today and wired it independant as stated above. I have to say, this type R is in a league of its own. It sounds incredible.

 

Glad to hear it..

 

pictures or it didn't happen

 

cool man congrats

 

x2...

 

If your sub is Dual 4, the only ohm loads you can get from it are 8 or 2. That being said, your only option with that amp will be to run each coil off it's own channel on the amp, but then you're only going to be giving it 250 watts rms grand total. It'll make noise but won't get very loud. What you want is an amp that can do at least 500 watts rms into one channel @ 2 ohms.....but those Type R subs are pretty good and can be given a bit more than rms power too....I have a buddy running a pair of them on 1500 watts rms with no problems for the past year and a half.

Not so much. The impedance always changes when you connect the coils together, it either doubles or halves, never stays the same. But you're an accomplished db drag guy who's doing 159+ out the trunk, you knew that

Not so much. That amp isn't stable down to 2 ohms mono so doing so would surely send his amp into protect due to low impedance. OP, don't ever set your gain based on a hypothetical math equation, that's not what it's for or how it works. Set it via DMM if you have one and know how, or the "by ear" method will have to do. It'll be where it'll be.

Yep, that's one of the benefits Class D amps are also more efficient and pull less current than multi-channel amps too.

Agreed, turn away from this amp if you can. But only because it won't give you the power you need at the impedance you need it.

Dude, who plays their sub up to 100+Hz anyway? My subs play nothing higher than 80, and sometimes I think that's too high. My mids play everything higher 80 and up to 5k and my tweets play from 5k and up. Given his power on tap from that amp, his best bet would be to use a ported box, he'd get more output from that than a sealed....not too sure what you meant by "good equalization control" but either way it's not necessary.

Yes on the resistance, no on the power....that amp isn't stable down to 2 ohms bridged.

Each channel runs 125 watts rms @ 4 ohms, you're gonna be seriously underpowering your sub running it like that so make sure you gain is set properly and take it easy on the volume ****.

What other subs have you had/heard? How did you end up wiring it up? Did you keep that Kenwood amp in your first post?

 

No offense to anyone.. But does he have proof to this.. I doubt 2 15" Kicker L7s rear facing in a trunk in our cars would be able to do that.. Was it a test that is official.. and also considering that there only 750 RMS each. The reading must be taken on the dash, and I want to see the results with driver door open and closed as well.. Ya im sure it can do this out of the port but thats a fake reading. If this can be proven this is a real test than I have no further comment. I just doubt those subs can do that.
