Adding 2 more subs question

[96firebird311]

First, yes. You will have to connect the subwoofer in the stealth box with the other two subs in the milhouse. Next, I guess I skimmed over the part where you said these are dual 4 ohm subs. [img]graemlins/slap.gif[/img] With three of them, you'll have two wiring choices. Series/Parallel for a 2.67ohm load or Parallel/Parallel for a .67ohm load.

Chances are great that the .67ohm load will be too low for any amp mentioned thus far. Especially since that's just a nominal rating. Actual Re is 1.73ohms per woofer giving a final actual load of .578ohms!!! Obviously these are DC resistance specs and actual impedance will change greatly with frequency....a whole other fish to fry.... anyway, what I'm getting at is that you will almost for sure need to wire all three subwoofers in a series/parallel config for the 2.67ohm load. This will not allow you to pull full power out of the 1 ohm stable amps. For this reason, I recommend stepping up to the BX1500D.

you could get an orion 1200 those are stable at .5 ohm for daily driving.

firebird I was just about to bring up the .67 ohm load too. Would it be cheaper for me to just keep the W3 in the stealthbox wired to the 5 channel and then just buy an amp aimed more towards 2 W3's. Keeping my ohm load somewhat "normal" as opposed to the below 1 ohm or the 2 and 2/3 ohm. Then what would you suggest other than the BX1500D, or just run it how it would be.

So stick with the Hifonics amp then and run the 3 of them in a series/parallel, or run the 1 off the one amp and get a ~600rms @ 2ohm amp

I don't think the Orion is in his price range. But yeah, that would be great. [img]smile.gif[/img]

Alt, couple of issues arise while you attempt that route. One. You want each subwoofer to have the exact same amount of power. Pretty hard since your 5th channel is only outputing ...100WRMS?.. and the Hifonics is doing much more. Next, you want all the subs to be crossed over at the same frequency. Again, this is difficult because the knobs on the amps are probably poorly marked (as they all are) and are not always exactly accurate. Exaggerated even more due to the fact you're using two different brand amps. The idea is to have all the subwoofers play the exact same sound. This can be very tricky to say the least.

If you're really against running all three off the Hifonics, may I suggest either:
A) adding a 4th sub.
B) Sell your dual 4 ohm sub and buy three dual 2ohmers. You could do a 1.33ohm load with this.
C) Just buy one extra w3v2 and run them in the milhouse. Sell your stealth box on here. (Run the BX1000D)

not that I didn't want to do it, but I went to my electronics guy down the road that answers all of my questions and then some and he told me that either I'd have to spend some retarded money to get an amp that'd push the 900watts rms that the subs use at 2 and 2/3's ohm. (He's like THE audiobahn retailer in our area, I just go there for advice and information, they're a little pricy in the store). Given your quick math skills approx. what would I be getting RMS for those 3 subs with the Hifonics. Looking at the reposts on ebay I doubt they'll run out anytime soon.

[FireFighter]

Depends on what your final ohm load is going to be and which model amp you are useing. the bx1000d or the bx1500d.

[Alt space n]

It'd be the bx1500d at the 2.67 ohm load

[96firebird311]

Should be doing roughly 850WRMS. Not too shabby... and not running the amp at full tilt is always a plus.

Another note, box size plays a vital role in how your subwoofers will sound. Ideally, you want all your subs to have equal airspace. Don't know off the top of my head, but I bet the milhouse is a little larger then the stealth. This could be remedied by placing any solid object in the milhouse. Block of wood and wood glue will work perfectly.

My stealthbox is .6 as well as the milhouse, so I lucked out there. Guess its time to ebay and wait for things to ship.

Okay, went to the glorious world of Subthump and ordered the milhouse and the amp rack so I don't have to screw around with retarded mounting.

So when this all comes in I'm going to be happy, and I have you guys to thank for it!

Glad we could help. Keep us posted and take some pics. Got all your wiring already? www.knukonceptz.com , www.darvex.com and of course trusty ol' www.ebay.com

[FireFighter]

Yeah, keep us posted, it should sound awsome. I think I am going to sell my w7 and get 2 w3v2's.

Subs and amp arrived on friday, the Milhouse and amp rack are scheduled for tomorrow. Now I can't wait for the weather to clear up. I believe I will just take it to the place that has installed everything else stereowise for this job. I really don't feel like rewiring w/o a garage in the cold.

Where are the pics?!?!?
