Question about Infinity Reference 1052W Subwoofer - 10" Dual 4 Ohms Polypropylene Cone Butyl Rubber Surround Car Speaker

1 Answer

Blown sub, butIdon't know why

My Infinity Reference 10" 1052W blew about a week ago. It was in a small enclosed box with roughly 170W x 2 channels x 4ohms pushed through it. I used 2 channels, 1 on each coil. The speaker was not torn and when I push or pull on the speaker cone, I hear bass. If it just sits naturally, it doesn't work. Can someone tell me if it is repairable or what may have caused it? Thank you.

If you use a right channel on one coil and a left on the other different frequencies are going in different directions in each channel thus blowing a coil or badly damaging it-z

If the lights on your sub box aren't coming on it's either your ground of power wire came loose or the transformer blew. As for the subs, make sure all the connections are good, especially on your RCA wires. If your amp is getting power, then check your speaker connections. Also, make sure to turn the gain know up. The gain knob is located next to the RCA input on the amp. Let me know if this helps.

The amp may no thav eenough to push these subs, these are top of the line subs, they probably require a bigger amp, if you are running other speakers through this also, you certainly need another amp, or a bigger one with more channels. also double check all your wiring.

I'm buiding a subwoofer box. i have 2-12


Well, good luck sir. Your'e going to have a lot of cancellation and possibly some blown speakers out of al of this unless you actually build a box around the back of all of the speakers. the subs are fine but there will be issues with the speakers. Either way figure out your own loads of all and have 1 2 channel amp for the speakers or multi channel for the speakers and a mono for the subs.

It wont ******* work


I am not able to offer a for sure solution because I dont have enough information and can only seem to find small pics of this product on the internet so I am not able to view it well. So I will offer what I can to help.
Perhaps you are not using a 4 channel amp? There also may be a problem with the output terminals on the box itself..maybe the wires inside coming from the subs are not connected properly to the outputs. How are you testing each sub individually? If you are testing with speaker wires coming from you amp well then we know that you amp is working...if you have taken apart the box and messed with the subs to test them maybe there was a small mistake made when reconnecting the wires? Like a positive connected to a negative or something? Maybe a fuse blew on your amp if you have one, or in your car? I cant be certain because there is not to much info to go on here so I hope that what I have given has helped you in some way...if each sub is working when you test them then it is nothing on or with the box except the wires maybe being reversed on accident or a bad connection on the output terminals on the back of the box, make sure those are connected properly on the inside. Other then that its probly not the box...maybe your amp is not big enough to handle all 3 subs and you are running a 2 channel amp and blew a fuse? You may or should get a 4 channel amp if you dont have one...like I said not to much info provided so good luck to you and hope I helped in at least some way!! :)

Subwoofer buldging out problem


When speakers are wired in the wrong way the will do the "pushing out" you're describing. Basically the polarities have been reversed and if kept like this over a period of time will blow the speaker. Best thing to do is to disconnect the power by the negative on the amp and take out the fuse from the power supply. Check the wires running from the amp to the subs, negative to negative and positive to positive. I know it sounds basic but many people do mix it up! I would also check to see what channels the subs have been wired into?

Best way is to have one sub from channel 1 and the other sub from channel 2 for example. Or if its a bridged 4 channel amp, have 1 sub running from channel 1&2, and the second sub running from channel 3&4 still making sure of the polarities. Again this all depending what kind of amp and sub you have.

-----------------------------
For example;
A 4 channel (bridged) 1000W amp. 250W max per channel or 500W per 2 channels! So if you have 2 500W subs, by connecting one to a single channel will decrease subs ability due to the lack of power supplied. However by combining 2 channels you optimize the output!
---------------------------

Once you know all your wiring from your amp to subs are ok/good connections/good wires etc you shouldnt have to "wiggle the wires" to get it to work as this is just a bad connection. Also ensure that no 2 wires are touching. Make sure that the master volume on the amp is turned down. You dont need this to be on loud at all, in fact far from it or you'll risk damaging both the amp and subs!

Hope this helps!

2 sets of pos. and negs. on 10" infinity reference 1052w


This means you have a dual voice coil sub. It is probably a dual 4 ohm voice coil. If you hook up the left channel to one input and the right to the other you can safely push the sub but the amp will be running at a lower efficency. In other words it isn't the best amp for the job because it can't push max power to a dual voice coil speaker but it will work.

Subs cutting out


Agree with Kev. Even if the woven lead wire looks ok, it can still be bad. I unsoldered it, clipped a lil from both ends, and re-soldered it. Works great now.
