Phoenix Gold Phorum

i bought this amp a couple days ago. i have 2 12 inch boston g3s dual voice coil subs. i hooked all the wiring up pluged the fuse in and turned power on. played for about 30 seconds then amp red lighted.all amp settings were on low. i didnt even have a chance to turn bass boost up yet.i left it overnight and the next day i turned on and the amp was red then green then it would blow the fuse under hood. i thought the fuse might have been faulty so i changed it, when i turned it on again it was red then switched to green and blew the fuse.i unhooked amp and put my old kenwood in and everything works fine so it has to be the amp.i paid alot of money to hear my subs for 30 seconds lol anybody have any sugestions

Those amps are only 2 ohm stable mono did you wire your subs for lower imedance?

I am guessing your subs are dual 4's?

IF you bought it new then take it back, I ran a few of those amps to play with and they seem pretty solid and did well.

But taking them lower then their rated impedance will kill them fast as they are not designed for it.

the subs were wired exactly as shown in the pg manual that came with the amp.my buddy bought it in austin texas and has lost the recipt.i live in saskatoon saskatchewan canada

thats all i can think of too.

model of subs, and tell us how they are wired up

positive to positive on subs neg to neg and 1 pos wire to the left pos terminal and 1 neg going to the right neg terminal pos x x neg

going to take some tommorrow. i am putting this all in a dodge 1500 reg cab lol should be loud.i took the subs and amp out because i am getting alarm installed in a couple days and ive heard of shady alarm installers in saskatoon so i dont want them to see what im running.the subs and amp are in a friends shop.im going to shop tommorrow so i will take some pics when im there

subs were ran parallel and bridged at amp.bostons web site says that running parallel brings subs down to 2 ohms

Do you have the 7.5 amp fuses set correctly?
What do you have them set for 2 or 8 ohm?

If you have the two subs paralled you have either a 1ohm or 4 ohm load at the amp.

Did a little more checking.

The web site says to run a 2 ohm load you have to switch to SVC g3 subs paralled.

Try running one sub set to 2 ohms.

i had both fuses in both subs.so thats set for 2 ohms. so if i have 2 that would bring them down to 1 ohm? i dont want to just run 1.what would be a better amp that i could use so i can run both subs?

well you could just change the way they are wire back to the amp to a series, and that would show the amp a 4ohm load, which is safe, but the amp wont make max power either.

you could run a pair of smaller amps, one for each sub

what you really need is a amp that makes big power at 4ohms, or is 1ohm stable


the NEW pg mono blocks are 1 ohm stable, as are the xenon and newer exile mono amps.

you could also run a xenon 600.1 or 1200.1 at 4ohms.

i think i would like to try and find another amp like the one i got.so now im looking for the same amp and a 4 channel for my interier speakers.i only got to take 1 pic of my subs in the box then the batteries died and i left cam at shop.i just spent the last 5 hours re running all my wires and adding the 3rd set of rca.does anyone on this board have a amp for sale?like the one i got or a 4 chanel?

vw337 has a few of the v4001's (which are kinda cool becasue there are only 6 of those) but i dont know of anyone selling a 8001


one thing that you can do is run rca's out of the first amp's aux out, and then you can control both amps with 1 lpl and not have to run all new rca's

front back and sub is my 3 rca`s.i was going to try amp to amp if i can find another.the amp is now at a shop in town and i should here back soon. i hope its not to much to repair.i guess i will wait and see what they say then plan from there.i had to put my subs in lol im running on my very old kenwood 600 watt max amp.sounds ok but i know those subs can perform well in my little truck.thanks for the help.
