Will a sony 600watt amp run a 10 300watt 4 ohm sub?

First make sure everything is wired correctly, correct polarity and channels. If the amp is a 2/4 channel and 800 watts @ 2ohms, then you would wire your dual voice coil sub at 2 ohms to match the amps output. Same thing if your amp was at 4 ohms, it all depends on how you wire it. Now if your running door speakers off the amp then I would put in an equalizer to better tune it and make sure the amp is set at the proper channels with correct polarity. Double check to make sure your ground,power, and remote wire are getting a good connection

You can't bridge that amp onto a load lower than 4 ohms. So you can't bridge that amp onto two 4 ohm subs. To get the most power out of your subs is easy. Run one channel to one sub and the other channel to the other sub. 165 watts RMS is plenty for most subs.

no there are no xplod amps that are 2 ohm stable. only 4 ohm stable.

Sure is.

The sony is bridgable as follows:

100W x 4 @ 4 Ohm

100W x 2 + 250W x 1 @ at 4 Ohm

This will allow 2 channels to run 100 watts each @ 4ohms with an additional single channel with 250 watts @ 4 ohms.

The single sub channel is created by bridging channels 3 & 4

Only way to drop the impedance is to putting subs in parallel or to use 2 ohm subs. I will add you a link to wiring subs:

it depends on the amp what can it handle. will it do 2 4 or 8 ohm is it 1 ohm stable are the subs dual 2 ohms or dual 4 ohms. 1042s are dual 4 ohm subs so if you wire them both in paralel it will drop both subs into a 2 ohm load for each sub that is pos of one coil to pos of sec coil then pos to pos on amp and same with neg to neg to neg on amp. now if your amp is 1 ohm stable i would do both subs the same way you will get the most power out of the amp. but itll run a littl hot if you dont have adaquate power running to the amp. now i wanna think your alpine amp maybe only 4 ohm stable. i would run both subs like i had said pos to pos then neg to neg now both subs will be a 2 ohm load so what you do to bring it back up to 4 is you run the 2 bridged subs into a series which is pos from one sub to neg of the other sub the remaining pos and neg will run to the amps pos and neg. which will make it into a 4 ohm load. now the last scenereo is your amp is 4 ohm or 2 ohm stable. this is how to wire it to 2 ohms and not 1. take one sub go pos to neg then pos to pos on amp and neg to neg on amp this will make an 8 ohm load with one sub take other sub and do the same neg to pos on sub then pos to pos on amp and neg to neg on amp this will tell amp to run a 2 ohm load. 2 ohms is a good run for these subs if the amp can handle a 2 ohm load. now if you would have given the amp model number i could have looked it up to just give you what you needed but with this short info i gave all possibilities.

it has a detector that kicks in it will usually shut off your amp and it keeps you from blowing your amp the speaker may have to much power and amp may not push it it will start to protect itself

as long as the speakers are wired in parallel it should be ok dont wire them in series as they will overload the amp it is designed to run at 4 ohms

take the positive on the sub and run a wire to the other positive the run a negative to the other negative then to your pos and neg on the box do the same on the other side then tie your two positives and two neg together and you got 1ohm and that amp willl handle it all day
