I need a lil bit of help on this one. I've been running a 13w7 powered by a 1000/1. I have a 4 gauge wiring kit. The 80 amp fuse that came with the kit blew as soon as I turned up the volume(stock Bose setup in a 99 NIssan Maxima, I only added the sub). Then we tried a 100amp fuse and that blew as well, I used to have those fuses in a MAXI style, now I have ANL style fuse holder. So if Im doing this correctly, 1000 watt/ 14.4 should equal 69.4 amps. What is wrong here? Also what the hell is dual 1.5 ohm? cuz that is what the sub is....??? ugghhh i want to figure this out(I have everything set up correctly I just want to know the "behind the scenes" of it all) I was also contemplating the thought of putting the 13w7 in the house.(lol) I was referred to this power supply. https://www.sportsimportsltd.com/80ampfurelow.html Anyone want to help elaborate on this amp issue I'm having? Would this safely power the 1000/1? I need to figure out how much MAX amps the 1000/1 pulls, right?

4 guage power wire should be fused with a 150 amp fuse. Read here. Dual 1.5 ohm refers to the voice coil configuration or the sub. It is necessary to know this when wiring a woofer to an amp. No, I doubt there are in home converters at a reasonable price that will be near powerful enough for that amp. For 500 dollars you might as well buy a home amp that runs off 120volt instead of that converter. Car audio belongs in the car just like home audio belongs in the home. That simple. -------------

yea, i know car audio is to the car as home audio is to the home, but i just figured "what the hell..." you know? thanks for you reply

that is if the amp is 100 percent efficient and not accounting for losses ------------- Custom Enclosure Design

so then it would be even less than 69.4 amps? so therefore in theory that power supply I linked to in the first post should be good enough for the 1000/1 max need for amps?

No, there would be more current draw than 69.4 amps. Just add the 150 amp fuse mentioned above and you should be fine. The fuse is there to protect the wire in case of a short. The amplifier has it's own protection.

Are your 1.5 ohm coils wired in series or pararlell? ( God I wish I could spell that word )

Ehh? If you want W7 in the right home config. look up Gothom and Fathom on the JL websight.

Its also less expensive than the power supply you were looking at

no dice, 1,024 watts RMS into 4 ohms my sub is wired to 3 ohms, only other choice is .75 ohm! :eek:

what would happen if I would run that 4 ohm amp on my 3 ohm sub?

the amp would heat up a little more than its supposed to, and would produce a little more power, but not enough to blow the sub.
i actually did something similar to what you are trying to do.
i had an 8" velodyne powered subwoofer with a 100 watt amp for my house that i wired in parallel to a 12 kicker L7 to and it worked fine. the only problem was that if i turned it up too loud (and i mean very loud) the amp would shut down and go into protect mode. i could also only use one voice coil on the kicker,but that was a dual 4 ohm configuration.
in your case, if you decide to go with that setup, you would want to wire your voice coils in series to keep your 3 ohm load. im not sure how loud you'll be able to turn the amp up but i think it would work. if it doesnt work the way you want and you dont actually blow the amp you could probably just sent the amp back. just a suggestion, im definitely not an electronics engineer or anything but i have used car audio subs with home audio amps and it worked.
here are some more amps to look at :

it doesnt matter to that amp...between 1.5-4ohms its producing 1000watts of power. so three ohms is where you want to run that sub....if you run it down to .75 it probably wont be happy. as far as fuses...yea go with the 150amp because if i remember right our rep told me thats what it pulls...either that or 125. ------------- 2007 Acura TSX

I know that it doesnt matter to my 1000/1 amp, because the sub is what requires only 3 ohm and that falls in the range of 1.5-4 Ohm which the amp can do. Therefore, I would be able to use the amp in other applications..... What Im looking for is something to power my sub (or amp) to run inside the home. I would have gotten that Dayton amp off partsexpress if only it went down 1 more Ohm, unless someone can convince me that it is safe and any other recommendations. That power supply is quite expensive.

if you really want the W7 in your house, go with the dayton amp. my house amp was designed with an 100 watt 8 ohm sub in mind. i was running it at about 2.6 ohms which was pushing about 350 watts, maybe. that amp was a type a/b apm, and so is the dayton amp. its up to you, but if i had the money and wanted to put a w7 in my house i would biuld a good box and try it out.

I have an old mitsubishi tube amp running two arc audio 10's in my house. Check out craigslist and/or yard sales for an older power amp that is designed to plug into a wall. you might be suprised. Now if I could just convince Haemphyst to come up and help me design a TL enclosure... -------------
