How too hook my kac 7201 up to my two dual 4 ohm Alpine type Rs

I would think a 1000 watts would be enough for 2 10's.
You can hook up two dual voice coil subs a few different ways.
First thing I would check for is what ohmage your amp is rated for.
You don't want to push a lower ohmage than what your amp is rated to handle.
That is a good way to overheat & ultimately fry your amp.
After that, you can wire your subs accordingly.
If they are dual 2 ohm subwoofers, you can wire each of them as a 4 ohm load, 2 ohm load or even a 1 ohm load.
I would personally go by what the amp is ratted for.
Remember though, the lower you run the ohmage, the better base responce & harder the hit you will get.

Please check the impedance of those subs. Are they 4 or 8 ohm speakers? Do they have dual voice coils? this app may not be capable of handling dual voice coil four ohms and you're trying to bring it down to a 2 ohm mono.

I'm using that Alpine right now for 2-12" subs and I have compared it to 6 or 7 other amps this month and most were 4 channel 150Watt/Channel Bridged to 300Watts x 2 and found the Alpine to be superior in both sound quality and loudness. The Alpine has also not turned off even with full volume for hours at a time, Very solid amp I was very surprised due to it's size!

this amp is rated at 600w at 4 ohms and 1000w at 2 ohm so as long as you calculate your speakers to match the ohm specs of the amp you can hook up

parallel = pos to pos and neg to neg of the 2 speakres
2 - 8 ohm speakers in parallel = 4 omhs
2 - 4 ohm speakers in parallel = 2 ohms

series = pos to neg of the 2 speakers
2 - 1 ohm speakers in series = 2 ohms
2 - 2 ohm speakers in series = 4 ohms

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.

hook the positive to positive and negative to negative on both subs then run wire to the amp the amp will see a 2ohm load

Hello damasogrizzl,

The 2 sets of terminals are connected internally. Having 2 sets just makes it more convenient when wiring multiple subs. The amp is rated for 900 watts RMS into a 2 ohm load. The specs claim that it is stable at 1 ohm but does not give a power rating.

The Radial SD competition series from Phoenix Gold are rated to handle up to 600 watts RMS. If you have the model RSdC124 with dual 4 ohm voice coils, it would be best to wire the voice coils in parallel for a 2 ohm load and connect the sub to one set of terminals on the amp. If your sub is the model RSdC122 with dual 2 ohm voice coils, you should wire the voice coils is series for a 4 ohm load and connect the sug to one set of terminals on the amp. Wiring the voice coils in parallel will result in a 1 ohm load. And, while the amp may be stable at 1 ohm, the sub will be seriously overpowered.

Hope this helps.

If you have the Alpine SWR-1222D, that's a dual 2 OHM Sub. So, the way you have it hooked up to the amp ,it's 1 Ohm, and unless your amp can safely operate at 1 OHM, you are better off connecting the voice coils in series so the amp will see 4 OHMS. The link below will show how the connections are made to the amp. Look at example # 1.

It sounds like your amp is overheating.
Check to see if its location is well vented, in the past, I have had to install ports/ vents and sometimes fans, when an amp could not be relocated.
Good luck...

Dual 4 ohm subwoofers can only be wired @ 1 ohm, 4 ohm or 8 ohm.
2 ohm mono load is not possible.
You will need to use (1) subwoofer to get the 1000W out of the amp.
Wire both positives on one sub to + on amplifier and both - on the same sub to - on amplifier to give the amplifier a 2 Ohm load.
Add a second amplifier, or buy an amplifier that is 1 ohm mono stable.
You can wire both to the amplifier at 4 ohms 600W, but they will share the power and only see 300W ea.
