Need Proper Wiring for 1 Ohm
I am waiting on my Kenwood 6140 to arrive and I plan to buy an amp for my (Correction) 2 JL W0.4 subs. I was thinking of wiring them together and running a 1ch amp bridged down to 1 ohm. What is the proper way to wire the subs together to produce the desired effect?
Another question, I have a component set for the doors and the pre put specs of the radio are:
2 Sets of 2V preamp outputs (front and rear/sub woofer switchable)
So the rear output would go to the mono amp powering the sub, do i need just a 2 channel amp for the fronts or a 4 channel?
What are your thoughts on the power acoustik amps? Should I just use kenwood amps since its a kenwood receiver??
Thanks

Which W3 subwoofers do you have? And what is the impedence? Original W3's and W3v2's had dual 2,4,or 6 ohm voice coils. Most W3v3 subwoofers have single 2, 4, or 8 ohm voice coils. Also, which amp are you going to use?

Need the actual model/size of the subs to get the proper impendance from the JL website, then the wiring
A 2 channel for the fronts would be fine unless you wanted to go with an active crossover network.
Personally, I would go kenwood over PA, but that's just me

There aren't very many amps today that are 1 ohm stable. I"m curious what amp you're using. IMO a good setup would be a 2-amp system. The full range amp running at about 100w per channel and a 300w mono-block amp for the subs.

Thanks for the advice George. Would the Kenwood's be a good choice? Is there a particular set of RCA's I should get or just order some when I get the Amps. I had a 1f cap on my last setup. For something like this, should I get another cap and what rating one? Thanks again

These are the amps I was looking at:
KAC-9104D - Kenwood Mono 1800 Watt Amplifier
KAC-7204 - Kenwood 2-channel 1000 Watt Amplifier
Any other suggestions? Not trying to break the bank on these but dont want to buy crap.
Also, I only nee 2 sets of RCA cables right? How does say the front RCA pre-out power 4speakers? Front are components but I dont know what active crossovers are or how they work. What would you suggest for a entry level set?
Sorry for all the probably dumb questions.

I'm using KnuKoncepts Krystal RCA interconnects. They're a bit overkill as far as shilding goes, but I like the design, looks and the ease of which the length can be trimmed for a clean installation.
A 1 farad Cap wold work, but i reccomend at least 1 farad per 400 watts. A 1.5 would work best.

OK so I did a little reading on active crossovers. I think im sold on them yet still know nothing on whats good bad or indifferent. So if running a 2ch for the front components which are a 6.5 and a 4, what type of crossover do i need? Will i need a separate one to do the subs?
Is the KICKER KX3 ACTIVE 3-WAY a good one? It has 2 inputs and 3 outputs.
Help OB1-George-nobie!!...LOL J/K J/K
Seriously though, If you could help me design a decent sounding system with what I got I would really appreciate it. For the subs I was just going to put them in a stealth type box. I would build a custom one like I had when I did the nitrous but I cant build crap out of wood.

OT:
When you coming by the house to check out the turbo build? Its done now, just doing a few other things. Still have to tune it but waiting on meth parts.

if you're going to go active, This usually consists of a midrange driver (usually 6.5-5.25") and a tweeter. A good active crossover will have at least 2 sets of outputs per input (one high pass and one low pass).
here's an example:
http://www.crutchfield.com/p_1616XSG...ay.html?tp=117
Here's a one i found on ebay:
http://cgi.ebay.com/AUDIOPIPE-3-WAY-...A1%7C294%3A200
I'm using the Alpine PXA H701 with C701 display (you'll need the display since you're not using an Alpine screen headunit)
Assuming you're only running front stage, you'll need a 4 chanel or two 2 channels to effectively use an active crossover network.

The crossover you selected only has 1 output for the front stage. This means you're only crossing your tweeters while your midrange speaker try to play WAY higher than they were meant to.
Take a trip down to the local car toys or mobile 1 to hear some equipment, and try various setups. if you have it, take a CD of 320kbps audio and a wide varaity of music you listen to.

Hmmm, that might be the best suggestion yet. I know the "good stuff" cost the cabbage but I basically just want loud, jackhammer crisp, clean clarity that draws you into the music like your in the middle of the ocean. Music that like gettin into 20# of boost and hookin it for the first time ever.
Yea I know thats gonna cost out the yang, but if I can build it up in stages Ill do it that way. I chose that crossover because it has 2 inputs and 3 outputs. I thought that would be good for the front tweets, mids ( off the 4ch ) and subs off the 2. As I said eariler, I have no clue. Ill burn me a DMB cd @320 and head down to the store. Thanks for the awakening thought that i am an audio dumb ***...LMAO what happened to the good ole 8 track days??
