07 Altima 2.5SL non-BOSE New System & General Questions

[Blood1]

Hello,I’m a brand new user to both sites: http://www.nicoclub.com/ http://www.nissanclub.com/

I have a 4th Gen: 2007 Altima 2.5SL non-BOSE system.I mainly use my mp3 player to listen to music on way to work via the AUX in. (Sansa e280R)

I am looking to upgrade the audio system for a louder but clearer sounding system. I don’t need the subwoofer box. The bass from the stock 6x9s and the space of trunk really thump already.

I did my homework @ Crutchfield looking up all the sizes etc:I am thinking of getting the following for my car:Dash:Boston Acoustics S35 : http://www.crutchfield.com/p_0...html

Front Door: Infinity Kappa 50.9cs: http://www.crutchfield.com/p_1....html|or|Polk Audio db5251: http://www.crutchfield.com/p_1....html

Rear Deck:Infinity Kappa 693.9i: http://www.crutchfield.com/p_1....html |or|Polk Audio db691: http://www.crutchfield.com/p_1....html

Deck:Nothing fancy. I will just be using my MP3 player via the AUX in. Anyone have any suggestions @ $200~$300 range. I know I’d have to get either a Pioneer or Kenwood deck to keep the steering wheel functionality and using one of these: PAC SWI-JACK or PAC SWI-PS. What does PAC mean btw?

Amplifier: Nothing extreme, just something 4 or 6 channel @ 75~100W RMS. Lowest THD possible. @ $200~$300

Questions:Now before getting any of this I was wondering if anyone could tell me the following. I’ve search both sites, google etc and cannot find a clear answer. Most just turn up cars for sale.

1. What is the standard factory radio watts on my car? RMS wise.

2. Does my car have an amp in the stereo system or is it all ran off the head unit? I tried asking the radio install guys @ the BestBuy in Westbury but I wasn’t too confident in their answers. He said he thinks there’s gotta be an amp in this system somewhere. (if this is true has anyone taken any picture of the stock radio/amp on an 07 Altima and knows where it’s located?)

3. I know I have 6x9's in the rear and 6.5" and 3.5" in front door and dash but does anyone know if the two in the front are ran in 'component' mode? Meaning is the speaker wire that goes to say the Front Left Door speaker's +/- terminals, have wires coming off them and going to the front dash left speaker?

4. With the speakers I choose above, for the front door and dash, the front door sets are 'component' speakers (ie tweeter/separates) If I was going to use only a 4 channel amp could I power all 3 speakers on 1 line (FrontDoor w/its tweeter and then the 3.5” Dash)?[AMP] 1 Channel (FrontLeft)--> FDL+FDL_Tweeter-->Dash 3.5”

5. Does anyone have any recommendations as to where to mount/install the tweeters for the component/tweets/separates in the front? Any pics?

Again these are great sites for info but just needed to ask these questions as I couldn’t find the answers by searching. I also checked out the “FAQ - START HERE FIRST!!!:” Great guide and info in there. It answered a bunch of my other questions.

Thank you,Dan

1. Pretty low. I'm not sure exactly what it is, but most stock systems are usually around 10ish if I remember correctly.

2. The Bose system has an external amp. The base system has an internal amp (in the head unit). The Bose amp is on the under side of the rear deck on the sedan (I think?) and the coupe has the amp mounted on the floor of the trunk (right side under the foam).

3. Pretty sure in the stock system the fronts are component (but I'd have to check the wiring diagram on the FSM to be sure).

4. I would recommend only using one tweeter per side. Go with a component set and mount the midrange in the door and the tweet in the dash (unless you want a custom mount like Doc has). Then a 4-channel will power the front door/dash with one channel per side and one channel per side for the rears.

5. I have my tweets mounted in the factory 3.5" locations. It's probably the easiest to mount, but the hardest to image correctly. Fine tuning the system will make it work though.

As far as your other questions, I would recommend listening to the speakers. In my opinion, the Infinity speakers are pretty bright (lots of harsh high end). But some people like that. It is ridiculously important for you to hear the speakers before buying so you know what you like. It doesn't really matter what anyone else thinks (it is your car, right?).

I'm not sure about the decks in that price range. I would recommend either Kenwood or Alpine, as they seem to have the best controls. Many on these forums like the Kenwood units. I'll have to get back to you on this one when I've got more time.

For the amp, I've been really happy with my Alpine PDX amps. You can probably find an Alpine PDX-4.100 in that price range if you shop around. It is pretty small and efficient without giving off much heat.

Thank you very much Apple!!! Appreciate it.

I would like to know an exact number if anyone knows one, because I've measured it, and based on the volt and ohms I measured the Watts to the rear speakers is like 21 microWatt's and that just seems wrong....
