I've just recently brought a used 18 inch API sub for home use. It is like 1500W and it is just 1 big *** sub. I currently have a 12 inch sony sub already. My sony subs pounds nice too. How come my 18 inch subs don't pound at all. Even my speakers that produce little bass is better than my 18 inch subs. I know the 18 inch subs has not has max power potential. It is barely moving. Is that because my amps are not powerful enough to power the subs? Can someone help me out. I have a Pioneer sub vsx-456. I believe that's like 500W. So i need a powerful amp to power this large sub rite? Hope someone can reply me back. Thanx. The sub is for Dj use.

is the sub in an enclosure or just flopping around on the floor

your post has about as much information as a 7 eleven employee does in economics

Of course it is in a box. I never put a sub without a box because u can't hear any bass. All the air has been let out then. What other information do u need? It is a 18 inch sub with a 2 hole outlet in ported box. The dimension of the box is like half the size of a single bed.

well for starters you never mentioned how you are powering it

is it an active sub, meaning it has an amp built in, or passive hwich means your driving it with an external amp, or do you havre it just tied in with your home theatre receiver on one of the speaker out channels?

i think he meant its hooked up to the pioneer reciever

sound like you ave it hooked to your head unit... no way thats gonna put poout n e bass, its not a powered sub, meaning you have to have an aux power source powering it...

It is passive.It is powering the Pioneer amplifer. How do i make it powering the aux? I already hooked it up to the RCA, but then made it to mono channel and hooked it up to the sub out. I didn't get much bass or close to nothing. I have my amplifer hooked up to the tv so if i do use the RCA which input can i put it in? Someone hopefully can help me out thanx.

no the subwoofer has to have its own power supply... it has to be plugged into the wall all by itself with its own amp...
the mono cable will go to your recceiver - but only to get the signal, not to use it as a power source...

so you have the sub hooked up to the rca output on your pioneer receiver? OUCH

seriously, you need to hire someone who knows what they are doing because you have no idea.. sorry but its true

There is nothing for me to plug the sub in to get power. I got a little power when i had it hooked up to the speaker at the back. But it still didn't give enough juice at all. So i'm supposed to get a wire or something to get power from my subs rite? How does it work?

your sub is passive, which means it needs an amplifier to power it.

You need a dedicated amplifier, running it off your HT receiver wont work very well because

a.) its playing full range
b.) depending on what impedance the sub is it might damage the amp


You need to find a decent subwoofer plate amplifier, or use an external power amplifier, like crown, qsc etc and depending on if your HT receiver has a special sub out channel you can just plug the rca from your receiver to the amp.

You will need to run an external crossover if your HT receiver doesn't have a internal crossover that is adjustable for the sub out channel, but most plate amps have variable crossovers built in.

If you want a powerful amp I have a QSC 1200 for sale, good solid 300 watt RMS.
