I hooked up the amp and its just a surge of power and will not hit with the beat? How come it is doing this? If i hook up the positive speaker wire without the negative it also does this?

you need speaker wire. you will hook one end to the negitive on the amp and one end to the black(negative) spot on the speaker. then hook one end of the other wire to the positive on the sub and the other end to the red(positive) spot on the speaker

how do you have them wired? have you tried to cross wire or conect the speakers to gether

ohm load check the way you wired it if the amp can handle 1ohm make the sub 1 ohm dule 2 ohm subs hook the neg from one coil to the pos on the other then take the empty neg hook it bridged to the neg on the amp and empty pos to the pos on the amp also check to see if you hooked it up bacwards subs dont hit hard when they are beating in and not out

the speakers have a neg/positive wire make sure you hooked them up right easiest thing to do is hook up the power and start with two speaker wires once you have sound coming from a speaker label them with masking tape .

first you need to run a power cable for the battery to where ever you are going to place the amp DO NOT hook the cable to the battery until the very last just wire it to the amp for now.next you will want to ground your amp hook the ground wire to the amp and the other end to a solid piece of metal in the car this is very important if you don't get good metal on metal contact you'll blow a fuse. If you can hide it well strip back a bit of carpeting and use sand paper to remove all paint from the metal and drill a hole for a screw. once that is finished you will need to run a remote wire from the amp to the car stereo usually these are the blue wire on the harness in the dash. once that is hooked up run the rca cables (reds and whites) plug in to amp and then in to back of cd player. once this is all hooked up and fully secure hook the power cable to the battery make good contact and if everything is grounded right you should get the lights on in the amp. Next step hook up the speakers run speaker wire from the amp to your speakers make sure negative goes to negative and positive to positive or you'll get clipping and it will sound like ****. that's pretty much the jist of it. if you have any questions let me know.

remote wire turning on amplifier?
Ground for amplifier?
Gain improperly set?
Radio output crossed over above tuning freq. of enclosure?
Just suggestions. Not much info to go by.

cd players work without use of volume controls coax cables hook up's and then by setting reciever to proper button so sound can come out
you might have had a power surge that fried your system but lets look at easy stuff first
fuses
lines in properly and connected
test on an old sterio with speaker hook ups and test your speakers by plugging in to old beat box
make sure wires are not scorched
turn on receiver fm see if speakers work change channels to sterio and mono settings if speakers start to work on sterio or mono setting chances are power surge blew out your system
hope this worked

sounds like they have your sub amp in mono but they put the speakers in series which totally cancels the benefit of running your amp in mono. you will probably be happier if you just hook the left speaker to left plus and minus and the right to right plus and minus. Cuz even though subs aren't directional they do pass some higher frequencies that are and that dilutes the stereo effect.

parallel wiring. hook all 4 positives together and run to the positive output from the amp, hook all 4 negatives together and run to the negative output from the amp.

hope this helps,

First of all, make sure your amp is bridgeable. There are a few ways to bridge subs. series: hook one wire from the negative on the left amp output (or whichever is labeled on amp for bridged)to left sub negative. left sub positive to right sub negative, then right sub positive to the amp positive output.(like a big loop through both speakers) parallel: both speakers get their own set of wires, both negatives go to the bridge negative terminal, and both positives go to the positive bridge terminal. Series-parallel: A combination of the two. say two speakers in series, and one hooked up alone, but all to the same amp outputs. Bridging your amp/speakers basically lowers the resistance of the circuit and makes more current flow, more power, louder, harder hit. In series, it also makes both speakers do exactly the same thing, instead of "stereo sound" or L/R differences. What you're probably looking to do is Bridge in parallel. That will drop the resistance of the circuit the lowest, allow the amp to put out the most amount of current to the speakers, and allow your bass to hit the hardest. If your amp only has one output, hook up the same way as above. Just see what resistance your amp is stable down to. If down to 1 ohm, no worries. if stable only to 2 or 4 ohms, you may want to bridge in series to be safe. That will cause the resistance to go up, and will not pull as much current through the amp. The whole time, just remember Bridgeing and higher current mean HEAT so watch your amp. I hope this helped.
