subs question
 

what are the subs actually sappose to be hooked up to. The back speackers???

To make it simple, the subs are connected to an amplifier. All the power is taken directly from your battery.

You will need an amp and a crossover to hook up subs. You can use passive crossover which cut out high frequencies which the subs cannot produce, some amps come with crossovers built in, and also you can get amplified subs which takes all the guess work out of it. Subs are usually located in the rear of the car because of their nondirectional waves. To put it simple, if you had a regular speaker in your trunk, it wouldn't be very audible because small speakers use more directional waves which is why they are mounted where you can hear them (without any thing blocking them). Subs on the other hand don't need to be mounted this way and can be tucked away in the trunk out of view and still provide sound that you can hear.

exactly i coldn't have said it any better!! but one thing i'll add don't ever try and hook your subs up and run them directly off of your head unit you'll blow it because subs have such low sensitivity ratings as compared to little speakers, so you would have to run the head unit at full volume non stop and they still wouldn't sound that great........take it from me i uh madethe same mistake and paid dearly for it:(

First of all, the first response was the best for this guy.

Be realistic, fellas - if this guy doesn't know that you need an amp and that subs are not hooked up to the rear speaker wires, what are the chances he knows what sensitivity ratings and crossovers are? Even if he reads your posts - which ARE pretty infomative - most of it is probably going over his head anyway.

Badaman3 - you need an amplifier to run subwoofers. That's starting at the simplest point in the process.

And:

Not true at all. My Infinity Reference components have a sensitivity rating of 92 dB, and my Kappa subs are 93. Kappa Perfect subs are 94. Many component and coaxial speakers rate in the mid-to high 80's, while many subs rate 90 and above.

94 decibels of midrange SOUNDS a LOT louder than 94 decibels of bass. That's the way our ears work.

Reproducing bass requires lots more energy (watts) than reproducing highs. That's why the speakers are so big and need to move so much air to function. Hooking subs directly to a head unit will blow them from a combination of distortion and no crossover (sending high frequencies to the sub that it cannot reproduce).

It's got little if anything to do with sensitivity ratings.

that' what i meant to say:D plus i've been talkin to this guy on the pm and trying to explain this stuff to him:)

If you want more info go to a local srerio shop, it wont cost you any thing for good advise on subs and amps. But if you want to bye a good sterio it will cost you. I spent $12000 on my sterio but i only spent around $2500 on this boot install and the 2 x 15 inch fusion subs and the infinity amplifier. get some advise I hope that when you get subs they go hardcore.
