working on it.

They forget thgat You are on the other end of the country.

good luck y0!

two more posts... I think.

what? only, like, maybe 9000 posts are mine...

settle down kent.. we all like James.

*poof*

Remember about those amps we were talking about in the impedance rise thread? I have one coming this way. Wanna do some testing? <{POST_SNAPBACK}> You're kidding I'll have to catch You for a chat sometime soon... well, hopefully soon. Life pwns me lately. I'd You if I could play. -Nick

BTW - Denim - Each (0.9 standing dcr) coil is reading 9.25 ohm at burp freq. Meaning that each 2500d in my truck is seeing ~9.25ohm, so ~300rms maybe from each. My early estimate says that I'll be getting ~700rms actual/total to the 99 (total) before clipping sets in hardcore. Though, a NO TESTing done burp yielded 144.x on the Dash yesterday. That was without setting amps, HU, seats, or having the Blue Tops. I'll set the equipment up and work with seating et al sometime next week. I'll put as much testing into this box as I can before I build another. Try to get a nice output gain from a higher box tuning (to get the imp spike moved). I really dont wanna make a bandpass... but may have to If I'm gonna goto Steel Valley Regionals. -Nick Gotta month.

Caught up at SSA just in time to leave again. BTW - Denim - each 2500d in my truck is seeing ~9.25ohm @ 47hz (tuning). My early estimate says that I'll be getting ~700rms actual to the 99 (total) before clipping sets in hardcore. Though, a NO TESTing done burp yielded 144.x on the Dash yesterday. That was without setting amps, HU, seats, or having the Blue Tops. I suppose I should take this to the dedicated thread, eh. chit. -Nick

bout 10hrs. ? <{POST_SNAPBACK}> WHoa, NM. I was gonna ask if it was near you if you;d check into this place that sells Rainbow online. <{POST_SNAPBACK}> Sorry bro. I would, but it's the other end of this fair state.

That's why SPL competitors can run 134KW nominal to a (9) 3kw woofers.

It's odd because ported's generally PEAK around the tuning freq. Not dip to the lowest. But thats a generalization... I dunno the SS woofers well enough to go furhter there. Soory. Looking at your graph, with that box the lowest imp is 1.2ish. Any amp, stable to 1ohm will be just fine for music. As far as varying V goes... You still need the amp to adjust the amperage as well.. to maintain power. If you were to try to burp these @ 50hz, then You would want a BIGASS amp that is 4ohm stable. FOR BURPS, not music. But otherwise, I hope the thread here helped You. -Nick

bout 10hrs. ?

yea... what he said. sorry.

my grand cherokee pump/unit was $380 ish. for the part. we did the labor. Fuel is the only thing to cool the pump. chitty.

.

still? wow.

dub - D fort eh. or bleach.

20 pages? or more...

what that tells You is that You have a suprsing spike at 48-49 hz...? You say Your box is tuned to 25? Odd - impedance usually spikes around tuning, IMExperiance. For example, my DD 99 with Dual 0.9 coils - each coil reads 9.25ohm in box @ 47hz (tuning). Okay, well, I'll ASSUME that when You adjusted the sensitivity on the amp, You set it at 50hz (Per James' tutorial)... if so, You did something like: 40 volts x 1 ohms (for example) and called it a day. What this graph shows you is that in real terms, you set the amp for 40 volts x 3.2 ohm actual. Instead of getting 1600 watts, You are getting 500 watts. A difference of 1100 watts. I don't know what the dcr is for your setup though. RLP's are Dual 4.0ohm are 6.1 in series... so standing dcr should be 3.05 per coil (standard TC coils ). If You wired all (4) coils in parrellel, then You should see 0.7625 actual free air (27.8hz - fs). Now, per Your work up there, at 28 hz, actual in box impedance is: 1.5ish. Make sense?

hey... when did we lose our :offtopic: smiley?? LoL
