Ok just baught 2 new soundstream subs, [edit: link to ebay seller deleted], they are 1 ohm dual voice coil...

And baught an alpine PDX MONO amp 1.1000, which is not 1 ohm stable, its 1000rms @ 2 ohms or 1000RMS @ 4 ohms...

is there anyway i can wire these subs up to this amp to run at 2 ohm? or should i get rid of the amp and buy a 1 ohm stable amp..

Cheers

... 2 2x1 ohm VC's.

wire it all in series to get 4ohm... you still get 1kW @ 4ohm..

Could ya do a diagram for me to do it in 4 ohm series? it would be something like this would it? http://img444.imageshack.us/img444/7114/wiringge1um3.jpg

Also i got an email from the soundstream people saying...

HELLO; YES, YOU CAN USE THE T4-15 ON YOUR ALPINE AMP, THE WOOFERS WOULD HAVE TO BE WIRED IN SERIES EACH TO GET A 4-OHM PER WOOFER. THEN YOU WOULD HAVE TO IN SERIES AGAIN TO THE AMP TO GET A TOTAL OF A 2-OHM LOAD WHICH WOULD BE FINE FOR YOUR AMP.

How would i "In series again to the amp to get a total of a 2 ohm load"? lol

cheers

Why'd you buy two when youve only got the juice for 1? I guess if one is f***ed and you get no love from bitaudio then youve still got a spare hey

well i didnt research just baught lol... so you recon just run one...? and have the 2nd as a spare?

Nah, you can run them both - you'll have more cone area i guess - remember that they need a big box though, and unless your prepared the sacrifice the 8cuft space for two boxes id seriously consider just running the one. BTW your diagram is wrong: Im working on the correct way to do it

O ok thanks heaps man i've been trying to do this for days lol, yeah my box takes most of my boot, in a VT Commodore haha

The SS e mail makes no sense at all, so either youve copied it wrong or theres been a serious breakdown somewhere. (you cant wire Dual 1's for 4ohms each woofer, and in series Adds to the impedance, not halves).

Edit: Deleted wiring diagram

oh ok so in the end it ends up being a 4 ohm load for the amp correct?

I'll teach you to fish so you dont have to ask about wiring again:

Edit: Good to see that ebay sellers have such top notch customer service they are so helpful they dont even know how to wire up the woofers they sell! And then there customers are forced here for advice. Chuckle.

Cheers for this, im gradually learning this stuff heh, but How loud should it be with the gain on half way? and volume 35/50, like BANG BANG BANG or like just normal cause it doesnt have that much power going to the subs?

... the gain isnt a volume control. read the tute on setting gains... you cant just whack the gain on half and go bob's your uncle.. you need to set it properly.



The volume of your system depends on how you set the EQ's, the gains, the bass boost's, the sub control, etc. the most important thing you need to remember is, firstly, to read the tute's about using/setting these things, and secondly, to make sure that you dont "over set" these functions and make the amp clip. if the amp clips(distorts the signal) it will cause damage to both the ampa nd sub, and will sound like crap.
