how much will new alternator affect W7 setup
I just got my system installed a couple of weeks ago and everything is done except for a high output alternator and getting tuning it. I have a couple of questions though.
What I have.
Head Unit: DEH-80PRS
Front Component Speakers: Hertz HSK 130
Rear Coaxial speakers: Hertz EcX 690
4 Channel amp for highs: Arc Audio KS 300.4 90W RMSX4 @ 4-Ohms
Sub amps: 2 Arc Audio KS 1200.1 1200W RMS @ 2-Ohms, run in master/slave
Subs: 2 JL 12W7s in a ported box.
Car: 98 Grand Prix GTP
Alternator: Current 105 Amp output stock, getting 260 amp stinger alternator (160 Amps at idle)
Battery: 2nd BAttery installed in the trunk.
I've been trying to do some reasearch but haven't found any answers on a coupld of my questions.
First, How much power are my amps putting out at 3-ohms? I can't seem to find that anywhere.
Second, what kind of power am I getting now, and what will I be getting with the new alternator. What will be the difference in sound I guess. The installer said he expects it to be huge, that the 2 sub amps are starved for power right now. according to my math, the alternator is putting out 1512W peak (105x 14.4) and will be 3744 (14.4X 260) after the new alternator is installed.
Everything sounds pretty awesome right now, the only real issue I have is that when on lower volume, I have to turn "Loud" on to get bass. I hope that this changes with the new alternator, and amd wondering how you smart people that have experience in this think the alternator will affect the sound.
I don't know much about it all, escpecially when you throw in the second battery, how it draws from there.

each amp will put out around 1000w at 3ohms
with 2 good battery and no voltage drop under 12v you probably are getting the rated power, the HO alt will help to keep everything running fine but the amp wont be producing much more power... That's the problem with ported box designed to be loud, there's too much port area and you loose all the bass at low volume.
Also since you have an active capable deck, i would ditch the rear and power the front with the 300.4 (1 speaker per channel). This will give you more tuning capability and a better sound.

I'm thinking it's something to do with your box design as well. You have a lot of good equipment there with a lot of good power to it, I don't see why you shouldn't be enjoying all levels, both high and low. The only variable left is the subwoofer box itself.
I mean this might sound nuts, but I wonder what a sealed box would sound like. You have so much power going to the subs anyways, you'd lose a bit of output but in turn you'd get the low volume notes you're looking for (hypothetically, I don't know).

I thought about getting a sealed box but I would like to hearsolariums similar power first. I listen to more rock than rap anyway, and from what Ove read sealed will give you more of a "tight" bass, is this correct?

A sealed box will give you tighter bass response with SQ in mind however you do lose spl when going sealed. However in a system geared more to rock and alternative I would go sealed every time. More accurate bass response and tighter SQ overall. I tend to agree with DaVibe
With the power you have going to them i wouldn’t worry to much about losing overall volume when going sealed.
Look at your enclosure first before shelling out for the alternator

Could you elaborate on this a little more. Your saying dont even run the 6x9s, correct? How does that help for the overall sound? Sorry, but I'm pretty new to anything beyond the basics.

Without any other statement, I find this very unhelpful. Please let me know what you mean by this, and share some "correct" information about enclosures

Also with ported box group delay will be more important so that could have also a big impact on the sound...
