I was wondering, can the RD 7500.1D handle being wired down to .667ohms? I know on the RD website it says .875 ohms but i wasnt sure if it could handle and perform properly at .667 ohms??
I was thinking of maybe wiring 3 dual 1 ohm subwoofers together
Exactly, David. But he is going to be seeing 1ohm+ after box rise, so it should not be too big of a deal. A better charging system is needed for sure, though.
Sweet! Thank you D-money and Nick V that is what i wanted to know, and if the amp sees proper power what will the RMS be at .667 ohms? about the same as it is rated .875 ohms? I'll need a special set up to get 2 alts under the hood where might i go to find that? and each alt would only be putting out 220 amps (that is the biggest that will fit that motor), would 440 amps be sufficient or would i need a 3rd alt? are D3100 better than Kinetik 2400? i can get a pretty good deal on kinetik 2400, about $300 a piece
"but he is going to be seeing 1ohm+ after box rise"
hey, you would be looking at the RD7500.1 more than the D9 if your looking for that much power. or if you want to wait, we will be having a D13 coming out. IMO i might would wait untill the D13 came out. because with a .667 final ohm load, after imp rise you will prolly be sittin at 1.5-2 ohm's
the D13 puts out a whopping 10,000 watts at 1 ohm i believe so at the 1.5-2 ohm load you would be seeing this amp will be putting out more power than the 7500.1.
by the way, what vehicle do you have? i might can point you in a better direction for the alt's. ones that typically dyno out around 275 each and at idel do 150-160 each
I figured something better would come out, it is always my luck to get something and with in the next few weeks something new came out haha, i'll wait and see the D13.
"after imp rise "
what is imp rise?
what is the difference between D2 and Q1? they're both 4 ohms total whether it be two 2 ohms or four 1 ohms.
I have a 1973 blazer...i believe it is 1973 that's what it says on the tail light but i'll double check with the vin number but that's not important because it is the same body style from 1973-91 i believe and it has a GM 350 motor in it. Would going to 16 volt alt be better than a 12 volt alt? (then i could use the 16 volt batt from Kinetik under the hood) idk its just all thoughts i have running through my head and putting that much money down i dont want to hurt anything (or anyone) by doing something wrong hahaha
imp rise is impedence rise, which when your start playing music or tones, the pressure and tempature rising of the sub playing makes the over all ohm load go higher.
with a Q1 there are more wiring configurations
when its time to work on the blazer i will set you towards some top notch alternator companies
oooooh hahaha makes sense! So what do you think the imp rise would be of 2 D2 12" subs at 2000 RMS total if they are wired down to 2 ohms in a 3.2 cuft ported box? would it still be or close to 2 ohms?
Thank you D-money. Can't wait for the chevelle to be done so i can show what i have done. I like doing it myself...yeah there isn't instant gradification doing it yourself, but you dont have to pay over priced local stereo shops to do what you can do yourself and feel good that you can say i did it myself haha
correct, i have always done the work myself, i just cant see paying someone else. if i dont know how to do it, i learn then try it. plus by building your car yourself theres things you can do the way you wanted it done
the amps mentioned are much more likely to fail due to voltage drop when ran at such low resistance. That is why the are sying you will need so much electrical upgrade to run these amps that way. The amps can handle just about anything....... except low voltage.
Oh i see so what is the RMS (i guess you could put it) for voltage that the amp likes to see??
I was thinking about using 3 15" Alpha V.2 D1.3 wired down to 0.86667 ohms (it would be somewhere around 1.5 ohms after imp...which would put me between 6000 and 7500 RMS which is perfect) and running a dual 16volt alt set up with four 16 volt kinetik batts(including the one under the hood) would that feed it? And how does my set up sound? oh and in about a 12 cuft box(before displacement) square ported to 34 hz
