Hi,
my car has an amp and a subwoofer built in and it performs perfectly with the radio, CD’s, USB and SD card, but when i try using the aux input with my ipod, it cant deliver any bass and it sounds rubbish. how can i fix this and what other way can i get to use my ipod with it without trouble.
Thank you 
check the settings on your ipod turn off the eq. your head unit also may not be compatible with your ipod you should check the owner’s manuel

So you just dropped $800 for a good auto sound system. Now comes one of the hardest decisions you will have to make: do I get this system installed professionally or do it myself? While you may be very tempted to do it yourself and avoid spending another $300 or more having it professionally installed, you need to ask yourself several questions before you decide to do it yourself.
Can I Do This Myself?
The first question you need to ask yourself and answer honestly is “Can I really do this on my own?”. Installing an auto sound system is no easy task. It requires concentration, a certain proficiency at mechanical tasks, and a fair amount of specialized knowledge. Something as simple as running too small a wire can cause physical damage to your expensive components, and some of the more common problems like ground loop noise or alternator whine can be difficult to fix if you don’t know the electrical theory behind it all. Mounting speakers and your head unit usually requires some sort of modifications to your cars body and dash, and if not done properly can damage your vehicle and look lousy. Even installing a subwoofer requires enough knowledge of acoustics and how sound actually propagates to be able to build an enclosure that sounds good and works with your subwoofer rather than against it.
If none of the preceding examples made much sense to you, then you are probably better off having your auto sound system professionally installed. It will save you a lot of time, headache, and quite possibly money of you damage expensive components or your vehicle.
But if you have some idea what all this means, or are willing to spend a couple of weeks learning all the ins and outs involved, then doing it yourself may be a viable option.
Do I Want To Do This Myself?
Even if you either already are capable enough, or feel confident you could learn how well enough to do it yourself, you may not want to. For one thing, doing a good job of installing even the most basic auto sound system takes a lot of time and effort spent cramped in your cars interior. Wires, screws, and other things you have to get at invariably seem to be in the most awkward locations. In some cars, even getting the part of the dash off you will need to can be a nightmare. Having a professional do it can save you a lot of time and effort, and will usually wind up with you listening to the system you just dropped big bucks on a lot sooner. Plus, any shop worth going to will offer a warranty on their work. So if some wiring they install shorts out in the future, you may be covered for any damage resulting from it. This can be especially important in auto sound systems, since they are routinely subjected to vibration, shock, dust, and temperature extremes.
Sound Quality is Paramount
If you think that installing an auto sound system is as simple as hooking everything up and going off down the road, you probably don’t need to be doing the installation yourself. After hooking everything up comes probably the hardest part to get right for the amateur: tuning the new system. Things like crossover frequencies, overall sound balance, and the precise speaker locations can make a HUGE difference in the way your system sounds at the end. If you don’t know exactly what to listen for, and don’t have some audio tuning CDs, your sound will be very suboptimal. Even though it may sound alright to you, you will be amazed at how much better a properly tuned auto sound system can sound. A professional can more than likely do a much better job of this in less time than you can.

I am a speaker lover and I am working on constructing a powerful subwoofer cabinet. However, I need some help. This subwoofer is intended to be used at parties and at clubs to enhance the bass frequencies of songs. The rooms will be relatively large and I have a 2000w amplifier (just for the sub). I am considering building the cabinet to save money. So what I am asking is:
1) Where are there quality subwoofer drivers that I can get for large vanues for under $400? (Brand Names Please)
2) Where can I go to get enclosure designs for speakers?
3) Where can I get more information on building speakers? (More specifically subwoofers?)
Thanks for the Help!
Is it just me, or did that make no sense whatsoever?

So, i am building a subwoofer for my house, and I need some help. I am using this 1000 watt rms 10" driver http://www.amazon.com/Quantum-Subwoofer-Ventilation-Technology-Competition/dp/B00371AK8Q and this 1000 watt rms amp module http://www.parts-express.com/pe/showdetl.cfm?Partnumber=300-809 I am building my own box, so im not going to worry about that, but my questions is, I want to put a volume control on my subwoofer. I dont want to mess around with the gain or anything. Like this subwoofer has a bass colume control http://images.kenwood.eu/files/image/852/8/original/sw-40ht-bk.jpg My g51 logitech speakers have a bass volume control, and my dads subwoofer has a volume control (he bought his). So i want an actual plate that goes on the subwoofer that just control the volume of how loud the bass is. Can anyone help me with this, becuase i cant find one (Iv looked up "Subwoofer volume panel" and stuff like that already) Thanks guys!
Hey lance, do you think you could recommend a good suvwoofer to work with that amp? I found some 8 ohm drivers, but they are like 400 w rms. Thanks!
The gain is a volume control just by another name other wire you can also control the volume from the receiver if it has a dedicated sub out then it should also have the ability to control the volume or gain same thing…just different words…also you need an 8ohm driver not a 2 ohm…
