I am thinking of putting coaxial speakers in the door of my Ram where the 6x9 speakers are as well as swapping the dash 3.5 for some Boston Acoustics 3.5. Questions are, I have heard that the door 6x9 only get mid/lows and don't put out full-range, is this correct so if I hooked up a full range coaxial it would only get the mids/lows? Also, if I wanted a cheap and quick upgrade for the sound, I want to swap in some 3.5 Boston's that are 4 ohm. What impedence are the factory Infinitys? I wouldn't want to swap in something that is 4ohm on an OEM setup geared to run at say, 2 ohm or 8 ohm.

Thanks!

Yes the front door with the infinity system are only miss and bass. The factory amp would only play miss and bass on any speaker you put in. Best bet is to do like I'm doin, run an amp for your highs and run all new wires. You should be able to look on the bottom of the oem speakers to see wat ohm they are...

Are you goin to be using the factory cd player??? And using a line inverter for the amp?

Also...the factory amp is a high current design. The lower the overall ohm rating the more power the factory amp will put out!

The speakers in the Infinity system are 8 ohm. You're going to be disappointed in your sound if you are only replacing factory speakers with aftermarket. I just went through this recently. I worked with Crutchfield to find something that would fit my front door factory 6x9 speaker locations, and they warned me ahead of time that nothing I was going to put in the factory speaker location with the factory head unit / amp was going to give me the same bass response as the factory system. I didn't listen and went through a couple of speakers trying to find something that would work.

First, you are limited because of the mounting depth. You aren't going to find 6x9's to replace the factory ones that will fit because of depth. If you go with a 5 1/4" , 6 1/2", etc... you aren't going to get the bass out of them that you would with the factory speakers. It's frustrating. The factory speakers are cheap paper cones that distort really easily. I ended up blowing mine up, so I needed replacements. When all replacements failed, I called Dodge. Wow. Sticker shock. They want more "per speaker" than you would pay for almost all aftermarket pairs of speakers.

In the end, my choices were:

1) Live with the reduced bass, but slightly cleaner sound of the aftermarket (which I did)

2) Go with factory. Yech.

3) Rewire and go with an external amp, new speakers, probably a new head unit, etc... I passed on that. $$$$ + I'm getting older and grouchy. :) In my younger years, this would have been the route I went.

Hope you find something you like, but I can almost 100% guarantee you that you will NOT like the sound if you simply replace the dash and front door speakers. You won't get the bass, and you won't get clear mids. It's going to be muddy and weak.

All the best,
Glenn

GREAT info guys. So basically if the factory are 8 ohm and the replacements I put in are 4 ohm, they will have less resistance and maybe sound better/get louder?

Maybe...

You have to remember that you are going to be driving the amp a bit harder and that equates to heat, which could shorten the lifespan of your amplifier. When I replaced 8ohm factory speakers with 4ohm, I actually think my speakers were the opposite - they were not as loud as the factory speakers. I could tell a noticeable reduction in loudness and sound quality. I went through more than one pair of speakers trying to find the right combo. The worst were the Infinity Reference 6030CS. I was only using the woofers and they were horrible. Very low volume and almost no bass. I ended up using Boston Acoustics S65RC's. They were decent at first and got better with time. I've never "broke in" a speaker before, but it seemed the harder I pushed these speakers, the more they loosened up and the deeper the bass became. They discontinued that model this year and replaced them with the SR65, which I am almost certain is just about identical. Very few cosmetic changes to the tweeter area.

All the best,
Glenn

Glenn is correct. Kicker also makes a great add on system you can get their Mopar kits.You can get the plug and play 4.1 amp, and the Mopar 6x9's in the door, which are not papercone and sound way better than the Infinity and factory. Then there is a 3.5" coax that fits in the dash as well, then you can add a sub all off this small amp.

they may be, why if you put another coax in place, most are 4 ohm, you'd use half the amps power. Bose did the same thing, so you need to swap alot to go from Bose to aftermarket. Pretty much need to gut all the Bose gear.
