new car audio. HELP

Seeing as you're having your head unit installed, I would assume you'd be looking to get the rest of the system installed as well?

It also depends what your goal for the vehicle is, and what you're looking to get, because components for the most part need to be purchased with other components in mind so that you end up with everything working well together.

If you're wanting to replace all of the vehicle's speakers, you'd want to first look in to finding some good sets of either coax. or component mids/highs for your dash/door panels, etc.. Coax being 2, 3, or 4 way speakers, which are the woofer with midrange and tweeter driver(s) built on to the speaker. Coax speakers are what you will usually find at walmart and depertment stores. These will suit most people's needs, as long as you go with a quality driver manufacturer (stay away from most walmart stuff, even the good brands they carry, like pioneer, are still the lowest end stuff that most audio shops won't ever bother with). If you want to spend a bit more on speakers for higher fidelity, higher output sound, and possibly more for the install, you can look in to component speaker systems. Component speakers feature seperate woofer and tweeter, as well as a crossover to handle basic high/low pass freq. filtering to each driver. These setups allow you to place the tweeter up on the door triangle in front of the side window, or in a pillar, for better sound staging and quality. Some newer vehicles come with these types of speaker config. Once again, either route you'll want to stick with higher end brands from a reputable dealer. Some I'd recommend from experience are CDT, Infiniti, Boston Acoustics... you generally get what you pay for.

If you intend to replace all the interior speakers, as I guide for above, keep in mind the investment will be best utilized by driving the new speakers using an external high range amplifier, most usually 4 channel. This takes advantage of most quality speaker's power handling of 50 - 100 watts RMS, which most 4 channel amp's will put out at 4 ohms, or sometimes 2, depending on wiring configuration.

Once again the amount of knowledge required to do a total install is vast, and you'd be best to go to a shop so that a professional in person can set you up based on how much $$ you hand him and what you're looking for out of it all.

You can go the route of a 5 channel amp these days which can drive, as you wanted to add, some subwoofers, as well as the highs. Some of the new 5 channel amps have all the crossover's built right in and low pass for the sub channel, with a respectable enough output to run some mid level 12's and maintain decent quality.

It comes back again to how much you're looking to spend and if you're going to attempt to do it yourself or not. If you are I'd be willing to assist further but I'd recommend doing as much research as possible first, before doing anything

I've been doing car stereo work as a main hobby far longer than my cannabis culture, and there are a vast number of things to know to get the job done right

 

How many speakers your jeep have? 2 or 4?

2 12s can be made to sound excellent with stock speakers.

Does you deck have a High Pass Filter and Subwoofer Low Pass Filter setting? Or something similar? You can just throw up the model if you aren't sure.

If so, you can easily send just the bass to the subs, and just the mids/highs to your stock speakers. The stock speakers will handle them fine running off the power from your head unit.

The subs then play just the bass, which they are well suited for.

How much room does the back of a cherokee sport have? And how much you want to spend on the subs and amp and wiring or install?

I run a similar setup in my newer jeep. Its an 2006 Commander, I run a pair of Infinity 12s powered by a big 2 channel amp. I even use the stock head unit and just the crossovers on the amp.

I used to take an approach similar to the first reply, in that I tried to get more and more equipment and more sophistication. In the end, my best systems have always been the simpler ones with gobs of power to some nice subs.

Jeeps have some very simple electrical systems, and are alot of fun to work in.

 

Car audio is not rocket science its pretty easy once you get the gest of the things that are important, so do a little research and save some money by installing it your self. Also never by from a stereo shop the mark up is insane usually 100% or more if you must use an audio shop for the install go for it, but i suggest shopping for parts else where.

I have had great success with ebay, if you have any questions about components just link them up here and I'm sure one of us will be able to help you out.

p.s. a budget would really be helpful
