Move your amp to a place in the car where it gets more air than it does at the moment so that it can be kept cooler for longer...

How do i wire a kenwood amp to two 8in woofers

at low volume any speaker works impedance mismatches wont matter(thats the 4 or 8 ohm resistance speakers have) , but at huge volume you need to consider a crossover circuit in the wired line
or a booster amp that does it for you.
when you have a huge volume level, the coils will feed back (counter emf ) some of that power back into the transistors driving it.
some transistors can die if mismatched badly at power up with high volume level. or disconnect while runnning a load.
depending on the amps design..
hot plugging anything is taking a risk no matter.

see page 8 of your manual below

either bad ohm load or over heat if the ohs on the speaker wires to the amp are lower than specified use in the manual it will act funny cause it is pusing harder than its meant to and if it gets too hot either bad location or bad amp you can try turning the gain down a little until the amp stays on constantly at high volume

Kenwood KAC-9152D monoblock

The amp says it's 1 ohm stable, so assuming the DVCs are dual 4 ohm, you should be able to connect all "+"'s together and all "-"s together, like the picture below:

As for the amp shutting off for a few seconds, it sounds like it's either:
A) Not getting enough power at high volume.
B) Overheating.

The cap on the +12V to the amp should help, but putting a meter on the +12V might tell you whether it's dropping too low (<11V).

When you first turn the volume up, how long does it work fine before shutting off? Is it with the vehicle running or not?

Since there's been no response in over a month, I guess I'll assume the problem was fixed!

when your amp cuts out,is it when your stereo is produceing a long low note.if it is then the problem lies within the power distribution from the your sub pulles a long low note it draws a lot of power and sometimes the battery cant supply the power fast enough and the amp cuts out. useing a power cap is one way to solve the problem,but the best option for you to use becouse your running high powered amps is to have a sepparate battery for your audio using a split charging system.when your car battery is fully charged a relay swiches the power so that it charges the audio battery,so your auio system will have constant power without putting stress on your car battery. you can get thes from all good audio shops. hope this helps you.

Amp keeps overheating

Try to turn down the volume??? LOL No really most likly the voice coil is overheating on the speaker, or the unit is over heating. Try to add a fan on top of the unit as I found this on high powered units, that they are being push hard and getting hot. Is the amp really hot when it does this? If it is then its a normal thing as not enough venilation. if its not hot then theres a problem in the amp and should be bench checked by a pro with load resistors and a tone generatoe as well as a scope to check if theres a clipping problem in the output stage.
