any other ideas on amps guys?

tCeeJay

whats the final impedance to the amp?

shadow_shifter

becareful with 1 ohm loads very few are stable and if there not stable they can mess up your system

YanksFan

That ED Nine.1 will handle 1 ohm daily, no problem.

As for an amp for you w7, maybe a phoenix gold xenon1200.1.....regulated power supply does 1200rms @1-4 ohms.

for around $250 or lower:

or my used ed nine.1 for $150

amps over your listed price:
alpine pdx1000
Rockford Fosgate Punch P1000-1bd
Orion HCCA-D2400
Memphis 16-MCD1000

Is the hifonics bxi1606 a decent amp? I was looking at getting one for my 13w7. Is that too much power? Let me know what you guys think. I found them pretty cheap.

trialsindude

I wouldn't go with a hifonics amp, I always hear people saying it doesn't do its rated power.
That 13W7 will handle a lot of power if you know what you are doing.
Also for RF don't do their Punch line, if anything go with the Power series.

jesterscourt

Anyone else feel the same about hifonics? The price is so good, but I defenitly dont want to put a crap amp on a good speaker. Any other suggestions for a cheaper route but without sacrificing too much quality?

tCeeJay

heres a forum discussion on that hifonics:
http://forum.sounddomain.com/ubbthre.../1#Post1310216

I think this sums it all up,
"all depends on your budget. the hifonics amps are hella bang for the buck, but if your willing to spend the cash you can do better."

jesterscourt

ok well I think after reading that and a coupple other things I found online I might take a shot with this amp. I know I can do better but money is a factor here for me. I'll let you know how this turns out.

jesterscourt

when I get this amp, how do I go about wiring up this sub to the amp?

jesterscourt

tCeeJay

I'm not 100% sure, but I think that sub is a dual 1.5ohm voice coil. If you wire it up in series you'll see a 3ohm load and in parallel you'll see a 0.75ohm load.

Here's a wiring diagram from our friends at Elemental Design:

tCeeJay

from searching online, i believe you're only option is to wire the sub in series @3ohms. Thats because almost all amps (Even the JL 1000/1v2) are not stable at .75ohms. Maybe you're better off getting the 1000/1 since its supposed to supply 1000watts even at 3 ohms.

YanksFan

Correct me if I'm wrong but since the sub is dual 1.5, wire in parallel to get a .75 ohm load. Taking into account for box rise and what not, would it not be more like a .9-1 ohm load?

Or get a Phoenix Gold Xenon 1200.1....does 1200rms from 1-4 ohms.

tCeeJay

you may or may not be right, but I was just cautioning on the safe side. I also looked on other forums and the majority of opinions was to go the 3ohm way.

jesterscourt

ok that sux cuz I bought the amp already. I thought I could run it in parallel. Now it will be under powering the sub if I wire it in series. What would happen if I did run it parallel? Would it blow the sub or the amp?

nodsetse

^ No, you won't be "underpowering" the sub, it'll be fine wired in series @ 3 Ohms with that amp, you'll have plenty of power AND some in reserve for improved dynamic headroom.

Don't try it in parallel, as it's possible you could damage the amp once you turn it up. That shouldn't happen, as the amp's protection circuits should prevent damage, but it could. Also, it'd likely be fine at low volume (most amps will handle lower loads that they're rated for...until you turn up the volume a bit), but then either activate it's protection circuit, or something worse.

Hey guys just giving a progress report here. I got my jl 13w7 yesterday and man I cant believe the shape it is in. I bought it on ebay and really lucked out. I totally expected there to be something wrong with it for the price I paid but this thing is in mint condition. I paid $310 for it counting the shipping. I also got the hifonics amp in, I'm not sure when I will get to building my new setup but I hope to start soon. I'll continue to keep you guys posted.
