Re: How much for upgraded electrical system
Just thought I'd drop this in, it's the reply I got from crutchfield about the amplifier:
As for the wiring diagram you referenced here, you’re correct in that this is how you would wire your two subs to a conventional mono amplifier.
However, the cool thing about mono amplifiers like the Kenwood KAC-9105D that have two sets of speaker outputs, is that all you have to do is wire each of your subs to each of the speaker outputs on the amp; so no special wiring configuration is needed.
And lastly, the Kenwood KAC-9105D is well-matched for the power of the subs you have. When you connect your two Kenwood subs, the amp outputs its 2-ohm rated power (which is 900 watts RMS). As a result, each sub gets about 450 watts RMS – which is still compatible with the 400 watt power handling of each sub as you can typically give subs up to about 15% more power than they’re rated for. I hope this information is helpful.

This^
For Jordan, 2009civic is right, 4 gauge on the big 3 or bigger. I'm also using 0 gauge. Also, if you use CCA (copper clad aluminum), you need to go bigger than if you use OFC (oxygen free copper), the 4 guage or larger recommendation is for OFC.

Hmmmm, one of my posts was deleted, that had truthful information in it. Looking at this thread, it seems an administrator is a vendor for the company I posted truthful information about. Coincidence?

Re: How much for upgraded electrical system
Or it could be that the information has gone far off topic...
Read the title again, I actually still haven't gotten my answer as to how much I'd expect to pay for an upgraded electrical system.
But somehow this turned into a subwoofer/electrical company war...it's actually pretty much a joke of a discussion now, kinda sad.
Like I said before, thanks to the people who gave me advice/information that wasn't biased by their own personal opinions.

Actually, you went off your original topic first.
So far, 2009civic is the only person to have given reliable information in this thread reguarding your original question.
There is not really a reason to upgrade your electrical for that amp, unless you are going to be playing test tones at full volume. That amp will put out no more than 900 watts before starting to clip. On music, you'll never see more than 450 watts average, since almost all music has a crest factor of 3db, if you listen to loudness war era stuff. If you listen to better recorded stuff, your talking 6-10db crest factor, or 90-225 watts on average that you'll actually be using. Real quality music, old rock, classical etc, has as much as a 20db crest factor.
If you want to upgrade anyways, you should be able to figure out the cost of the big-3, as installing an amp, you should know the cost of wire, fuses, etc.
I was running 1100 watts of power on a stock 85 amp alternator on a 12 year old neon, and the lights would never dim, voltage would never drop. That same system will be going into my wifes 2010 EX, with no changes to the electrical. Scott Buwalda, IASCA World Sound Quality champion, and record holder for the highest score ever, is running 6 JL HD750's on a stock Infinity G35 electrical system. Since you said you dont want it to be rediculously loud, just to sound good, there should be no reason to upgrade.

Your post was deleted because it was off topic. And if you're referring to me, you're sadly mistaken. No coincidence. Have a nice day.

Re: How much for upgraded electrical system
Let it go dude, the whole topic is a joke now, like I said.
Honestly, is it worth it?
Admin, I don't think I'm gonna get anything more out of this topic, if you want to I'm fine with it being locked and/or deleted. Kinda seems like this is gonna keep dragging on until someone kills it...

How much for upgraded Electrical?
New high output Alternator - $300-400. There are cheaper ones on eBay but I don't know of there any good.
Big 3 ground Kit - $30
4 Gauge Wire Kit - $80-100 depending on brand.
Like what was said 30 posts ago, hook it up before you get the alternator you shouldn't need it.
I think your right! It's time to close this thread.
