    An all in one unit? From wallmart?



    Im not putting you down, my first system in my car was wallmart. i have learned since that alot of there products are cheap for a reason, But lets be sure of what you got and what we can do to fix you up.

    I checked there web site to see if i could find what you describe but they didnt show anything.



    First, Is it one of those boxes that has like two subs and tweaters built into a box that has a set of wire connectors in the back and it comes with a AMP thats seperate that came wiith it?



    Depending on if it came with it or not you may need to get an AMP wiring kit.



    You run a Positive power cable from the battery, which has a fusable link in it, al the way to the amp.



    Then you run a ground from the amp to the chasis of the trunk ( if the amp is in the trunk anyway) or wherever you have the amp at. The shorter the ground cable is from the AMP to the chasis, the less interference you will get from the car and other devices.



    Then you have whats called the remote wire that connects into you cars radio fuse, the one that only has power when you have the car on or in accessories, but not when turned off.



    Then you should have a pair of AV plugs that go from the amp to the CD/radio player. This is for the sound or base. If you have a factory installed system in front, it may not have external base plugs and you will have to wire the sub into the back speakers along with a crossover or high pass filter so only bass gets through to the subs AMP. I havent done it that way before so you might want to read up on it. Instructions come with the AMP wiring kit and they tell yo how to hook it up.



    Let me know exactly what you have and provide a picture if you can of the AMP and the box and the connectors, that way i can better asist you.

I have a 2005 scion tc, everything stock. My bass just stopped working, the treble still works but there is no bass. Does that mean i blew my speakers? They still sound fine. Is there anything I can do...


check your fuse box and find which fuses go to your radio/audio system it may have a built in subwoofer and amp in the vehicle -check those out and hopefully it will solve it.good luck.

MTX 12'' sub noise


Sounds like your sub is overextending itself, and possibly losing contact at the voice coil. Overextending will make a weird rattling sound, losing contact at the voice coil will make a popping sound.

I just bought 2 12 incch explodes the xs-l126p5 modle and i have a 1000 watt explode amp xm-1652z modl. in a bandpass box. it dont sound the way i expected to. if you can help...


Did you have it hooked up by a professional or did you (or someone you know) do it. If a shop/pro didnt do it make 100% sure everything is hooked up right. Increase the size of your power wire from your battery to the amp. Check your gain settings on the amp. If the vehicle you have this in has a trunk (not a hatch back), position your speakers against the back seat facing you as your putting them in the trunk. If none of this works, buy bigger speakers and more power!

I just bought 2 JVC CS-DX30 12" car speakers. What kind of box am I supposed to get sealed? vented? ported?


You can put these in either a sealed or ported enclosure, not vented. Your box choice depends on what kind of bass you are looking for and the power of the amp you use to drive them.

A sealed box will give you more accurate bass reproduction but will require more power for a given volume. A ported box will be louder at the expense of sounding somewhat "boomy". You should really listen a pair of 12"s in each type of box before you make your decision. Some people don't like the sound of ported enclosures, others love it.

I'd recommend one of the enclosures here:

My car subwoofers work, but theres no bass


turn them off and carefully push in on the cone (gently) and listen for scratching or scraping- push strait in and they should flow freely in and out if they DO without feeling or hearing scraping the subs are probably ok, next its either the amp is not powerful enough or the box is not soundly built, by that i mean its too small for the subs- is the box ported or sealed? if ported try plugging off the vent temporarily and see if bass increases if it does i would permanently seal the box

Premier sub used to work great ... now nothing


Did you check to make sure that you didn't blow a channel in the amp? Another thing to check would be the connection on the inside of your box, maybe there is just a wire loose.
