Hey guys, i just got a system, a502 d.e.i. amp, and 2 single coil pheonix gold octane r 12's. Will a 8 guage power wire run this alright? My freind says i should go with at least 4 guage So the power can run more freely/faster. I dunno, what should i put in?

 

Go with the 4 ga. That way, if you ever decide to upgrade your equipment, you won't need to upgrade your wire, too.

 

You have two 12" SVC 4 ohm 250W "RMS" subs and you are going to run them with an amp the makes 2x90W RMS into 4 ohms or 2x125W into 2 ohms, there is no indication at DEI what the output is when bridged or if it is stable below 4 ohms when bridged or even if it is bridgeable, assuming it is bridgeable and not stable below 4 ohms, [like most 2ch. amps when bridged] it will make about 180W RMS into 4 ohms, [all the above ratings are at 14.4V and 1% THD+N]

The only possible way you could run it is as a 2ch. amp, [one ch. for each sub] 90W RMS into 4 ohms, kind of under-powering the subs big time.

IMO it is the wrong amp for those subs, it has just barely enough power to drive one of the subs, but any way you look at it, that amp dose not need a 4 ga. power cable, although as mentioned 4 ga is OKBCHA. 94

 

ok so what do you suggest i do? Should i just bridge it then? I have a year warranty on it, my freaind has the same subs but has a pheonix gold D800 amp powering the two octane r's 12's and they pound decent. Is there a bid difference between these amp with the exception of the power rating?
edit-how about if i trade my A502 in and get a Absolute ABS9070 amp? specs:
* Maximum Power Output
* 800W x 2CH (1600W) @ 20HM
* Power Output: 320W X 2CH @ 20HM, 220W X 2CH @ 40HM
* MONO: 640W @ 40HM
* THD less than 0.05%
* LPF (Low Pass Filter) Variable 30Hz - 250Hz
* HPF (High Pass Filter) Variable 50Hz - 1KHZ
* Bass Boost (0-18dB @ 45Hz)
* 2 OHM Stable Stereo
* Low/High Level Input
* Frequency Response: 20Hz - 20KHz
* Gain Control, Power Indicator
* Gold Plated RCA Jacks

Because you have two SVC 4 ohm 250W "RMS" subs I would find a mono block sub amp that makes 500W-600W RMS into a 2 ohm load, [two 4 ohm subs wired in parallel is a 2 ohm load] however although still a little underpowered, [2x220W RMS into 4 ohms] you could use the "ABS9070" in 2ch. mode, 1 ch. for each sub that is a lot better then 2x90W RMS into 4 ohms.
I can't find a P/G "D800" amp at P/G site so I don't have any info on it, the closest is a Ryval Dysigns A1.800d, 1x800W RMS into 2 ohms @ 14.4V, more then enough to drive the two 12" subs properly. 94

 

O my freind has a D800 Directed (d.e.i.) amp, so its pretty much the same thing except its mono, and more watts lol.

i've got an mb quart reference 2400 for sale if you want it... $200 shipped.. few months old... bought it brand new... still like new...

specs are:

-- 200 watts RMS x 2 at 4 ohms (400 watts x 2 at 2 ohms)
-- 800 watts RMS x 1 in bridged mode (4-ohm stable)

you can run each sub on each own channel and will be able to run 200w for each sub... a little underpowered but much much better than what you're doing with your current amplifier.. let me know if you want it
