Can my electrical handle it?

Alrite so ive been enjoying my W7 for a while now but i think i wanna run more this summer, well considering it rite now my factory alt was 80amp and i recently upgraded to a 125amp alt, running 0ga from front to the back, big 3 done in 0ga, battery isolator upfront and a second kinetik HC1200 in the trunk(installed hopefully this weekend), running a HD750 and an Audison SRX4, also a bitone.1 I know the audison has a 15amp fuse and i believe JL recommends a 60 or 80 amp fuse for the HD, here are my scenarios:

1. will my car handle another HD750/1 to run another 12w7?
2. Would it just make more sense to sell my W7 and run 2IDMAX off my JLHD?
3. any other subs i should look it for an SQL type setup? i like bass dont me wrong but on a regular day i just use my bass **** and turn it down a reasonable level, then i have my days when i just run it full tilt anyone have a recommendation?


p.s. anyone has a DVD/NAV deck for sale? single din preferably and one that doesnt drop when i downtown like the kenwood units xD

If your two amps are 1500w ouput @ 1.5 ohm than it's going to need 1500/.80(amp efficiency) = 1875W input. 1875/14.4v = 130.2083A. Add another 340W/.7/14.4 = 33A and a bitone.1 just call it 10A, it's just a signal processor.

I don't know if it makes less power @ 1.5 and 2ohm as the audison needs a 15A fuse yet it requires double in, maybe it's 340w max not rms? I'm not sure how to calculate it.

You also need to power your car, which I don't know how much it needs. You should fully power one amp but not two.

How much to cars generally use of their total amps on their own?

the 2 amps will be running 750 at 3ohms each, the third amp will be running about 240RMS at 4ohm and i believe audison says the bitone.1 will be safe with a 1amp fuse so using the formulas i will need roughly 160amps just to run my stereo and roughly 50-60 amps for my car so if i go dual HD amps i will need roughly 220amp alt :/ yikes maybe i will stay away from that then lol

If the W7 isn't already, port it.

it is in a made to spec ported box, just after a while you get used to it and u want more, on a daily basis i dont crank it unless its realllly nice outside and im with friends, but then again id prefer to have a bit more and turn it down like i normally do maybe ill just use the gains on my amp as they are at 0 right now lol

do you ever get the urge to just right a response hastily?...like I read "can my electrical handle it"?......
and without reading the ensuing info or responses you just write"no,....no it can't"


is that just me being an a$$hole?...........or has anybody else wanted to do the same thing?
