Default Two subs to one amp?

I am asking this question while trying to help a friend.
If you take two subs, wired separately, then twist the positives together and put them in the positive channel of a 1500W mono amp and do the same with the negatives and the negative channel, will both subs receive 1500 watts?

^^ wireing mess
yes you will get more watts with runnng both positives and negs on both to th same neg and positve on the amp, you will be 1/2ing the ouhms, and doubling the power ot put , in therory, 3000 watts,, lol, not likely,
if you want to make it more stable
run positve to positve on one speaker and brdge the neg to the other speaker positve, then run the neg from that speaker to the neg on the amp,, thts 1/2 the power 750 watts but more control, hence usally less distortion,

But if both of the subs are drawing the full 1500 watts then wouldn't that be too much for the amp to put out and eventually fry it?

well
lol
1 amp @ 12 volts makes 12watts
if your fuse to the ampliphlier is a green 40 amp fuse
you are limited to a max of 480 watts b4 fuse pop
so 1500 watts is unlkley
the ampliphlier if pushed to distortion and beyond will damage the speakers
most amps are rated @ 4 ohms,, so going to 2 is not extreem, dropping to a 1/2 oh, is extreem, and wll most likly clip the amp,,
if its not distortin,, its problay ok,,
what knd f amp is it,, i would know better with that

Delicroix, I have to ask, " who wired your stereo"? You are asking a pretty simple wiring question that your signature would lead one to believe you already should know. Of course, I'm refering to you having a Kicker L7 wired parallel to a bridged Audiobahn amp.

I wired my stereo on my own. I have a good understanding of stereo wiring when it comes to multi-channel amps. But I'm asking questions for a friend of mine who plans to get a pair of Kicker 12" L7s, he was looking for the best amp configuration to power these at 2 OHMs. My brother is running two BOSS subs into a mono amp by twisting the positives together and the negatives together into the corresponding channels. And I was just wondering if that would be an effective method for these subs on an amp that is rated at 1500w x 1 @ 2OHMS, since L7 12s are rated at 1500w peak, and the amp is as well.

well kiker subs are a good start,
your brother running boss subs to a mono amp, ( what kind of amp),
you will not reach 3000 watts in a normal car, so dont worry about over powering the subs,
worry about cliping the amp, and sending distortion to the speakers that will burn voice coils,
make it easy
just get the Kicker 10ZX1500.1 it is a perfect match and will sound awsome

So if he were to get that amp, should I tell him to wire it the way I asked about or is there a more effective alternative?

If he is wanting a 2 ohm load, he needs to make sure he gets the L7s with dual 2ohm coils. He will then need to do a combination of parallel and series wiring. ...or get the dual 4ohm version and parallel everything and get a 1 ohm load.
