Hey guys, long time lurker... occasional poster here...

Anyways, i recently bought a 2000w Volfenhag 2 channel amp and 2 10" AudioPipe 500w subs... and ive been noticing that i cant get them to hit very hard before they start going on the bad side of sound...

My question is, did i choose a bad type of amp? Or was it the speakers i chose? I have plans to add a 3rd sub to that, since my amp allows me to ghost a 3rd sub on it, so i dont wanna get some bad speakers if thats the case. any help would be appreciated.

Honestly, probably both are bad.

yea i got a volfenhag amp\subs combo. they sound clean but htey dont hit hard. but also keep in mind that out of 1200watts max they are gettin like 240 watts...

well since its only stable into 2ohms, the subs will wire up into a 4ohm load. so you wont get much power. that would explain why they arent loud. same problem with my set up

nexibat

So my problem is a little of column a, and a little of column b then?

Question for ya nexibat, what size box do you have the subs in, ported, sealed or bandpass, and are you running them one to each channel or parrellel bridged at the amp

Twidget722

Actually the amp is stable at 2 ohms when one speaker is on one channel, if it is briged it should be at 4 ohms. if you run the subs parrellel the total load drops to 2 ohms and if you bridge the amp it might work but it also could run really hot and cut out, of worse fry the amp.

with two dual 4ohm woofers running on a 2ohm stable (not 1) amp, what are all the possible set ups? this could be a start for help

simplespirit

coils and subs in parallel = 1 ohm
coils in series and subs in parallel or coils in parallel and subs in series = 4 ohms
coils and subs in series = 16 ohms

you get what you pay for. wattages shouldn't be the deciding factor . i have 2 JL Audio 12W6 on a JL Audio 500/1 amp and it seriously hits too hard for me.

sraudio

wire each sub in parallel for a 2ohm load on each then just put a sub on each channel of amp and turn your gains up a little bit if the gains are to low and the head unit is up real high in relation the your amp is amplifing distorded signal which gives muddy sounding bass. you should also check your lowpass crossover and make sure its about 65 to 70hz that will tighten the sound up a bit as well

nexibat

Thanks for all the help guys, and as for the box its a two chamber sealed box

check you wiring. If your amp is running 2 ohms and your sub is wired for 4 ohms your only using about half of your wattage. Read your manual for proper wiring.

Install is everything.

i don't think he cares really about your equipment...

Actually I found that post saying what he had running off of 500W being plenty loud to be quite insightful/useful...
I'm considering an upgrade to my sub stage myself, I want it to hit hard but I don't need it to induce nausea. I'm actually considering something under 500W under the passenger seat and going for SQ. I have a JL W0 under the seat now running off of around 150W and it sounds nice but doesn't hit hard enough for me.
Sorry for rambling, I realize from your comment that you don't care about my equipment

shinkuu

the point i was trying to make was you don't need monster wattages to have subs that hit nice and hard. the subs i have are 300watt rms and the amp is 500 watts. im sure they hit harder than the two 500 watt and 2000 watt amp that nexibat has.

maybe 2 12s would suit your needs better nexibat. i might actually go down to one 12 but then again, i'm running them on a stock headunit with stock speakers. once i upgrade the rest of my system, i will be able to accurately gauge the performance of the subs and see if they compliment the rest of the system.

im going to be running two JL 10's on 1000w and install is the key to nice sounding systems

StackTrayce

When people say "install is key" what type of stuff are they referring to? Nicely built boxes, setting the amp gain correctly, running the proper load (ohms) on the amp, wiring, setting the EQ correctly?
I'm pretty new to high end car audio, but I've read a lot and constantly hear people talk about the importance of the "install" but I don't know exactly what they mean.
