alpine iva w 505 off ebay about 500 bucks its a good sound quality unity but the nav isnt the best i carry a garmin cause that thing had me down back wood country roads goin in circles you can get the 999hd for less than 1000 ive bought mine from abt electronics 930 you call them and make an offer you will be surprised how much they can knock off also sonix electronics spelled diff though is also a good bet as well i have tried allmost every amp alpine pdx is the best with the smallest footprint you can mount them in that hole where that awesom bose sub goes lol

is that box ported?

i am very new to learning about 370z's sound system. but from what i gather in this thread (and a little of others) if i were to install those speakers in the first link, with a touring model. i would want to get some kind of double din head unit (with the two things i read you need to buy if you have the bose system)

would i need to buy an external amp or would the headunit amp be adequate? and if i did those things if i didnt buy new rear speakers i would have to turn the factory ones off? and lastly if i were to do those things i would also want to replace the sub right?

Options
 

A lot of 'ifs" in your statement. It depends what you want from/looking from the sound system. If you have a BOSE sound system in your Z, then an aftermarket amp may fit your needs. The amp could power the front,sub, and if you want rear speakers.

The BOSE sound system has a specfic OHM rating for the BOSE speakers. An amp can be located in the rear hatch or under the seat depending on its size.

Im having some focal tweeters and speakers installed today along with duel 8" subs with an Alpine amp. The amp had to be Alpine to get ther hertz right with my head unit, somewhere in the 3000 range. I will be going to pick it up in the next hour or so and am told it will be incredible. It is rather expensive but I will let you know how it turns out.

I am also not doing anything with the rear speakers as the Nismo does not come with any.

I would love to hear this explanation. Any brand amp would have worked, No matter what they told you. (must have been an alpine dealer)

Speakers
 

Check out Hybrid speakers.

sorry i think i was a little tired when i typed that one out.

anyways i have read something i think that said you have to replace Everything when you have BOSE. so i what i meant was can you replace speakers, and ad a sub in the trunk with out adding a head unit and only having an amp. or do you have to really replace everything. hopefully that is a bit more clear.

Maybe I should have worded my post a little bit different. The amp they were going to use was a JL and it would not go into the 3000 hertz range. The Alpine amp they had was about the same price with the same specs and would go to that range, so they suggested that was a good option. They work on the Porsche cars here that we send them so I trust their opinion. I am by no means educated on sound systems, I just want it to sound good :tup:

I thought we didn't have stock rear speakers? There just duds. Unless some models do have them?

I added 4" JL C5s back there.

I'd replace everything, speakers, and add rear speakers, subs and two amps.
