Need answers to a couple ???

1. I'm gonna throw a 2000 rms amp on my HDC3 (I doubt i'll use all of that). But if I have a kinetik up front and one in back, can my 105 amp alt. handle that?

2. My box in my car is 4 cu.ft. tuned to 40, the port is right up against the back and the sub is back also. I heard that in SUVs, you should have sub up and port back but the port should be at least 5 inches away from the back, would I notice a difference if I changed to that?

Thanks.

1. i really doubt it. i was dimming a decent ammount on my 135a on 1200wrms.

2. yea, it messed the tuning up. why such a high tuning if this is a daily?

1. I think it'll be fine overall, I just wanna be sure. I was running around 1300-1400 watts on it for a while and got little dimming.

2. Dude....it's an HDC3.......It likes the 38-40 tuning.

Dude 2k rms aint shit, you will be fine...

I ran 2500 with no extra batt and stock batt.

I probably won't even be running the amp that hard anyway.

That's what I figured, thanks.

But now......what about my second question......?

You may run into equipment or electrical issues but your amp 99% of the time wont be even at half output.

The second one, I don't know. Just have enough room for the sub's excursion and you shouldn't be able to notice unless you have a sharp ear.

I heard that you need to have the port away from the back so the air has more room to flow or something, lol.

When I had my memphis prs (in avatar) the box wasn't bolted down so it moved a lot and I could tell when it moved up against the back because the bass just wasn't there. I'm just wondering if i'm crazy or not.

if possible, just turn the box on its back and have the sub and port facing up. problem number 2 solved.

and your electrical will be fine. I run 2kwrms off stock 70Amp alt and batt and big 3 and only dim when at full tilt on bass heavy songs. you'll be fine

......I think what i'm gonna do is.......build a box...sub up, port back away from the back of the car....and see what happens.....

At least we got number 1 solved

You'll be just fine electrical wise, as long as u don't beat on it all day long.

 

4ft3 @38hz, 50-60sq in of port, sub up/port back works best in my SUV experience (but play around w/ different boxes and you'll find the one that suits ur setup/vehicle properly)
