Simple Speaker Recommendation for Base...

FoesFlyDennis · 05-30-2009, 11:39 PM

Hi Robert,
I've been considering doing the Infiniti Kappas in my own base model 370z followed a little later with the same Kenwood deck. I'd prefer not installing any other amplification so I think the increased power provided by the DNX7140 might drive the 2 ohm Kappas enough to fill the tiny cockpit. I appreciate hearing from you that the Kappas were a significant improvement in sound over the factory speakers and that they fit easily. Have you heard any warnings about the 2 ohm speakers damaging the amp in the new head unit you'll be installing? A sales kid at a local chain audio store was saying to stear clear of the Kappas for this reason. I am thinking that actually the Kappa's lower impedence will provide more sound volume with the rather low powered amp of the head unit. Any other thoughts or experience is appreciated. It's great when you are doing exactly the same thing someone else has already done (or is doing). Are you also not planning on installing a sub? I don't listen to rap or hip-hop. I'm a classic rock guy; Led Zep, Badlands, Whitesnake, etc.

Be very weary of using crossed impedence speakers/HU. You can run into some issues with using a 4ohm deck and 2ohm speakers. If it was the other way around, you'd be ok. I'd stear clear of doing this if you can. You could do some serious damage to the H/U if you're not careful.

Kind of jumping in this late, sorry if I touch upon already asked questions.

Concerning the base Z, is the conclusion that the door speakers are fine and the thing to replace are the rear speakers? And if those are replaced, would you need an additional amp, or is factory sufficient?

well the base z doesn't even have rear speakers. it has 6.5"s up front and some 2.5" tweets in the dash. so the real question for you would be can you put rear speakers in the z and the answer is yes. anything you want really, I suggest a new headunit and amp to power everything.

Wow, I actually thought there were rear speakers. Oversight on my part.
I do like your setup tommy.

So, maybe replacing the door speakers (they're 6.5" I believe?) with 6.5" alpine type-S speakers 240w, and 1" alpine tweets? I want to keep the stock dash to keep the stock look going, so I was thinking a 500w alpine amp.

Tell me what you guys think.

Thanks for the props. Speakers are a choice that can only be made by you, as far as the amp is concerned, I think its way to much power. 80watts x 2 is more than enough.

Well, I was thinking of getting the 500w so it can cover if I decide to get a sub later.

But, if I get a 200w (up to 4 channel I think) would be enough to power the two 240w speakers and maybe a small 10" sub later on?

Also, aftermarket 6.5" speakers should fit right in, in place of the door speakers right?
