Question about front, overhead speakers, and amp

I currently have the factory radio and speakers in my 2000 TJ. I have the 2 fronts and the overhead sound bar. I was thinking of putting in a new stereo deck with 2 new front speakers and 2 new overhead speakers with an amp. Will that make it sound a little better, or would I have to add a box inside the Jeep to really change up the sound?

I'm not very smart with car audio but I first changed out the factory deck to an aftermarket kenwood deck and that made a huge improvement on the stock speakers.

Then I put 6.5's in the bar and 5.25 in the dash with templates i made out of license plates and that is a HUGE improvement without an amp running them

for the best results you should first look into a new headunit, just adding a head unit will make the factory speakers sound better, and it will also make it much easier to ad an amp. how much are you looking to spend?

Thanks yea, I priced out some stuff and the new head unit, new speakers and amp came to bout 600 including the install. It's more than I want to spend so thats why I was asking about this. If just putting in the new head unit will change it up, then I might just do that for now.

thanks

Jim

Head unit first, you can do this yourself easy enough with a mounting kit and wire harness where you don't cut any of the factory wires. If that's not enough, then speakers, 5.25 with brackets up front, and 5.25/6.5 in rear. You really don't need the amp for those speakers. Then look for an amp/sup, 8/10" later. You can do this closer to $600 if you can do it yourself. check out crutchfield, comes with instructions/harnesses and brackets if you buy a head unit from them.

Ok here's the deal. I used to install stereos and the one thing I quickly learned is that stock speakers suck! They are made out of paper and are crap. An amp would help but with a good head unit and new speakers you will be able to hear with the top off which even the premium stock stereo out if my 04 wouldn't do. If you have factory sound bar I would by 4x6 for the front 5.25 for the overhead an a deck should se you back less then 500 for a good deck and mid level speakers. If you really want to get the most out of it also get a small sub. I'm not a bad person but when your in the freeway at 70 mph top off stereo cranked the lows will distort your small speakers a lot. A deck with a high and low pass filter will only put the range the speakers they are built more for. Also a sub and a two channel amp is uaaually cheaper then a 4 channel by it's self and you won't be removing your lows so you will still have distortion. So IMO it's best to do a deck and speakers first then add a small sub and amp. The 8ohm speakers aren't going to mix well with a new head unit anyway I blew mine our in two days.

Ah and do it yourself its really easy installs are outrageously priced on jeeps because they are so easy. If you need instructions send me a message.

i put a new head unit i mine with new 6.5s in the sound bar.....and it still sucks. IMO...even with new everything, you'll be disappointed. esp. if youve been listening to good sound before getting the jeep. a box and amp is a nessessaty but for what i do with the jeep, theres no where for all that, so im stuck.

Truck sub box with the amp mounted on the box. I fit mine right behind my seat and strapped it in. Saved time and space above building buying something custom.

Putting a new head unit in with the same power output as what you have now won't help improve sound quality enough to hear in the least. It would take a sophisticated piece of test gear to determine the difference between two different properly functioning head units with similar RMS wattage power outputs.

If you also install an auxilliary power amplifier, your choice of speakers is expanded because the added power the aux amp provides will allow it to adequately drive those speakers that require more power.

But you can still improve your sound significantly without adding an aux amplfier with proper selection of speakers. The key thing to look for when selecting speakers for a head unit without an aux amplifier is the speaker's Sensitivity rating. The higher its Sensitivity rating, which is expressed in dBs (decibels), the better it will sound because a high Sensitivity rating means it doesn't require as much power to make it play loudly enough to make the sound enjoyable.

Sensitivity ratings you will be ok with will be anything over 90 dB. Once you get down into the 80's, especially the low 80's, the more they need an auxilliary power amplifier. One brand of speaker that generally always has high Sensitivity ratings of at least 90 or 91 dB rating is Polk.

There's really not much to it at all. Remove the trim piece the covers the defrost vents. Under there is two screws (on mine at least ad every tj I did at circuit city was the same) take them out and the trim peice around the heater controls and the head unit will come off. Check for extra screws some models have screws in the front. After that just unscrew the head unit and unplug it. To put a new one in you need a dash kit and an antenna adapter. I also recommend a wiring harness because lest admit it you may have to put your stock stereo back in at some point since we are so prone to ferric them stolen. If you want to get really fancy you can get an overhead locking console for 250 bucks or something from quadratec. I built my out out of diamond plate for about 100 after getting my stereo jacked in Vegas. 1000 miles home with no tunes... It was a long trip. GL man hope this helps

I went through the same sound dilemma a few months ago. Replaced the stock head unit with a Kenwood MP345U, replaced the stock 4x6's in the dash with some low end Focal 4", replaced the soundbar 5.25's with some Pioneer Premier 6.5's that I had never installed in another vehicle and finally disconnected the stock subwoofer in the center console which was blown. The improvement was OK but not what I had hoped for. Finally, broke down and took it to a local, independent, car audio shop and had them install a four channel Kenwood amp under the driver's seat with two channels powering the 6.5's and two channels bridged to power a JL Audio 10" sub with enclosure behind where the rear seat would be. Now I am very happy with the sound as I can hear it perfectly cruising along at 70mph with the top off.
