You need a low pass crossover set at 80 hz & below. It will stop the music you hear in the sub. Don't expect the feel of a single 10 in a room to be like the same sub in a car. A car fills with pressure & gives the feel you want. A ported box designed to work with your sub will give you 3db or more output than a sealed box.
For optimal performance there is really only one size for the box .Firstly, you get two different types of subwoofers, an open air, or closed air sub. If it is an open air sub ( hole with mesh in the center of the magnet) no ports are required, and the box should be sealed on the inside with silicone sealant. If it is a closed air sub ( no hole in the magnet) you need a 50mm port about 120mm long. Box size will be 11 inches x 11 inches x 11 inches. Hope this helps
Hey i'm no expert either but maybe just maybe your amp has a subsonic filter on it which cuts out the lowlow bass maybe check that and either disengage it or turn it all the way down if it even has one thats all i can think of unless you have a ported box and going below the boxes tuning frequency other than that im as stumped as you are-good luck with it
i beleive that underneath some dustcaps is unsealed. the dustcap in some subs encloses the motor that drives it. I would suggest getting it fixed in 1 way or another just incase. Having the motor exposed( if it is) can burn out if unattended to.
I hope this helped.
are you gong to use this in your house or car?? any type of enclosed box air tight.. will do if your useing it in your house a box you can face the cone faceing down would be good with a port in the front about 3in would be good. be sure to purchase a cover for the speaker you dont want the cone smashed .you dont want any air leaks .. you can go to any car stero shop and have a box built.if you have good wood working skills build it your self 1/2 in partical board works ..you can also get the port tube at like a raido shack.and speaker port for conections weather it be rca or speaker wire type do not nail your box wood glue is best
Try taking tha cable out of the amplifier and touching it, this should create a low hum, as your body is sending throug a small current. if this works then you may have accidently switched the sub woffer on in the amplefier. if however you get nothing through the sub then you may have a dry joint in the solder, or the board may be dead. Other option, try an other cable. they also use lead based solder so they do get old.
just connect your subwoofer mono RCA to your amp sub single out rca connector. you do not need to megre all those 4terminals into one. in fact internal circuit of those 4rca are merging inside to one since the sub uses only a single amp. 4inputs was meant for sources with multiple sub out
