Doors and dash speaker wiring

[Eventix]

I'm swapping out the OEM speakers in my Dodge Ram Quad Cab with equal size but aftermarket upgrades. Speaker sizes are as follows:

3.5's in dash
6.5's in front doors
5.25's in rear doors

I haven't purchased the dash or door speakers but I was leaning towards Soundstream's Tarantula line.Soundstream's Tarantula
Odly, the Soundstream speakers are 3ohm.

For lows I'll be using two Kicker CompVR 8's powered by a Crossfire VR401. Head unit is Kenwood's KDCX791. I have a Crossfire VR404 for the mid and high range.

I would like to keep use of the rear speakers but put emphasis on the fronts. How should I wire door and dash speakers? The two scenarios I have considered thus far are:

1. Power the dash and front door speakers with the VR404 and rear fill with the head unit.

2. Power all speakers with the VR404 by wiring the dash and front doors in parallel (1.5 ohm, amp is only 2ohm stable)?

Suggestions are appreciated? SQ is my objective but I do like to crank the Aphrodite and Rancid.

Hi Eventix. If that amplifier is stable down to an impedance of 2 ohms I think it won't be able to power the Tarantula's down to 1.5 ohms. But, if you had your mind set on the Tarantula's then maybe you can wire them in series to present a 6 ohm impedance to the amplifier. However, I have never wired anything besides subwoofers in series. It might be worthwhile to ask the manufaturer or a retailler. See if you can acquire like a wiring diagram possibly..
I know of mono block amplifiers stable down to impedences 1 ohm. However, those are usually subwoofer amplifiers.
Another option too is to use Crutchfields "Outfit my Car" feature. By entering data specific to your vehicle, you can see what speakers (or components) can fit your vehicle. You might want to look and see if Adire Audio sells speakers that conform to the dimensions for your specific vehicle. CR has kind of been a ghost forum for a while. Possibly, Easy E or CVStroker might be able to help .

I thought maybe someone here may know a little more about risk associated with running mid/high range at slightly lower impedance (1.5 vs 2 ohm). I have read that risk isn't as great as is with subwoofers.

I haven't made the purchase. I like to try the lesser known gear vs. the mainstream (i.e. JL audio, pioneer, alpine etc.). Adire? I thought they were finished http://www.adireaudio.com/. REaudio would be nice but they don't sell 3.5's.

Whoops... Sorry about that Adire recommendation. Didn't know they closed their doors.

Why are you putting down my advice? I just thought I would try to help you out since Easy E and CVStroker haven't been here for a while.
If you're so sure about running those Tarantula's in parallel off that amplifier, then why come to the car audio forums in the first place?

Sorry Kirk, it's easy to miss interprate a response through a short thread. I didn't word it in the best of ways. I appreciate and agree with your response . In fact, I'm looking around for something, non-mainstream, that is in 4ohm. I checked Adire as soon as I read your post. It's too bad because I would like to have sampled their full range speakers.

I still wonder if there is a difference between running high frequency speakers at lower then recommended impedance vs. low frequency speakers.

Oh, I'm sorry about that Eventix. I kind of misinterpreted that one sentence. To tell you the truth, I'm kind of a (Civil Engineer) Newtonian mechanics type of guy. Although I do know some about audio, just through experience.
I think Easy E can help you out here as far as impedance and wiring. Just need to be patient he'll come eventually. He's got a family so he can be quite busy at times..
And I can't blame you for wanting to stay away from the mainstream manufacturers too. Sometimes the best audio equipment you can find is through forums like this. Like Second Skin Spectrum for example.
But, I must say in all honesty, I don't know of an amplifier that's on the market yet that is stable down to 1 ohm that's intended for midbass and tweeter drivers. Just giving you a heads up. Maybe Easy E or CVStroker might know of one (or more) that I am not aware of. BTW they design their own audio equipment now apparently, so they can give advice based on education in audio technology and not experience alone..
Again, I am really sorry about that post. I misinterpreted what you posted. Good luck in your car audio ventures.
