Do I need a specific type of 4 gauge wire for my monoblock amp?

Go to a professional installer and save yourself the angina!

Crutchfield sells a wiring kit for $70 that has 4 gauge wire and a fuse.

Thanks for all the advice. I ordered a good copper wiring kit.
 I might get a stiffening cap for it too.
This is for a jbl bp1200.1 (car audio mono amp) *not home audio.

Ill be hooking it up this week. 
Thanks for the advice everyone.

Dont forget to mig weld a bolt to the chassis as close to the amp as possible and use "heavy" cable for the ground.I have seen many dodgy installations where the installers use a self tapper.When it does come loose the next ground is your front loader...which will be toast!I run 400+400wrms in both of my cars, at 130 x 2 it is mind blowing as i use hi fi 10's and fane compression'sThe frontloader runs the original car speakers..phoenix gold 6.5 x 4.PS dont forget to use a HQ battery in the mobile..I swear by Varta from germany, they can handle it and last up to 10 years.You may been to up your alternator unless you have a high current bosch.

Oh yes..and a nice big 1-2mf cap with a digital display to monitor the drop if any. Helps the alternator and battery for the low peaks.
Voltage drops = clipping+distortion = heat and bang!Good luck..blow your mind..that power in a car is insane..people often ask what i am running, one word...HI-FI.
