Stereo install

lol hey there is nothing wrong with that fish we all have our areas that we are moronic to. lets see if i can answer all your questions for you. for your question about the port on most modern head units some have a port that hooks to a sat radio receiver, some have a 1/4" jacks for use with i pod adapters and some have a usb port for again ipod adapters as well as thumb drives. as for wires there is a vast selection that range in price and quality in both speaker wire and power cables for amps. you've got your low end that would be installed into most average everyday rig unless you want to dish out a lil more for better quality, and then you've got the high grade stuff that is used in your bigger sound systems. as for what you want to look for when shopping for speakers, head units, subs, amps, pre amps and all other components that got in to building a sound system....1st look at your pocket book figure out how much you want to spend be it in one shot or over time. that was one of the first things we asked people at the sterio shop i use to work for. the second question would be what type of music do you listen to. there is a wide range of mid and high end speakers that vary in type of sound and quality of sound. to find what works for you with the type of music you listen to you will just have to listen to them.this will also be affected by the types of head unit, pre amps and amps you go with. this is due to the power of the signal that is put out. everyone has their own opinion to whats good and whats not. your typical chain stores will all carry the same brands with a small variance. the quality ranges from crap to decent. if your looking for something more i would suggest going to a specialty shop and looking. it also helps to do a lil research on things as well. ok now lets get into your boxes......the size and shape of the box is determined by a few things. 1 the shape of the area you will be installing the box. 2 the air requirements the sub needs to sound its best. 3 the type of box your using be it band pass ported or sealed. and last the frequency that you want your box tuned to. again that is all determined by the size, the type, and the power for the sub. for example if you take a 10" dual 4 hm coil sub that you have 800 watts to in a sealed box tuned to 34 hz then take the same box and put a 10" single 4 hm coil with 800 watts you will have 2 different sounds. as for the direction of mid and high ranged speakers the positioning of them does have some impact on the acoustics inside the car but unless your getting into a bigger sound system you shouldn't have to worry about them too much. again its all up to you and how it sounds to you. hope i got all your questions answered for you fish.
