[quote="trevorb27"]I was also wondering if i should be worried about over powering my door speakers? The front door 6.5" JBLs hold a rating of 60 watts rms each while the rear 6x9s are 100 watts rms each. I was really just looking for something that could give the rear 6x9 speakers a little more juice but unfortunately for the front speakers its a lot more. I understand earlier somebody told me not to worry about this. The 4 channek amplifer is rated for 600 watts rms and is 150 x 4 @ 2 ohms

Adjust your amp for the front speakers with the rear turned all the way down, then bring up the rear gain until you get a nice rear fill. 75x4 will match up well with your 500 watt amp on a sub.

You can do with the built in fuses, so you are good to go.

Dont worry about overpowering, you simply adjust the output on the gain switches on the amplifiers, thats standard..

Ok so i picked up a 0-1 guage to 4 guage dual amplifier wiring kit. It comes with a distribution block and a 200A fuse which i am hoping isnt too big but it was all i could find that was over 150 and i was told it is always better to overestimate than to underestimate. I did however notice that the kit didnt come with any fuses for the 4 guage wires however. Was i wrong for assuming that would be necessary as well? Feel like im getting different information everywhere as someone told me earlier today if the fuse is too much more it can cause an electrical fire lol my mono amp has a 60A built in fuse and my 4 channel has two 25A fuses built in. Thanks everybody. Im still trying to grasp this but hey gotta start somewhere or ill never learn

I would just like to stress the importance of remembering the fuses for each amp as well.


1 fuse (150-200A) near the battery on the 2 gauge to the dist block, and place the dist block as close to the amps as possible, and a then the fuses before each amp.

So you'll have the 2 amps (1 sub amp, and 4 channel for everything else?)

I would go with the 2 gauge to the dist block.
I didn't look at the specs of your amps, but a 150 amp fuse near the battery sounds right if you're using the 2 amps. That fuse is to protect the wire from shorts.

The from the dist block to the amps. Use the largest wire that your amps will accept.

that's about all there is too it :)

Ok thank you. I came across a good deal on a 4 channel amp recently so now irs just a matter of getting the wiring kits and everything i need. well i could use some help figuring out what i need. I currently have a kenwood x500-1 mono amp hooking up with a 8 guage wiring kit and a 80amp fuse. I recently bought a hofonics zxr616.4 4 channel amplifier to run all of the speakers. As far as wire it looks like i am going to need 2 guage wire 159 amp fuse with distribution blocks? I have been researching like crazy lately but i would just like to know for sure before i spend money on all this stuff. Whats my best route? Should i just add a second 4 guage wiring kit instead?

Hi Trevor,

Please do not focus on the rear speakers, that is not the way to go.

If you are not to run 4 channel amp for the front and rear, then use a 2-channel amp for the front, the rears off the headunit and a separate amp for the subwoofer.

There is no need to foccus that much on the rated performance of either the amp or speakers.

Buy the best amps you can afford/want to spend on the project, they are sort of the key point for any future improvements.

Ok then thank you guys. I guess my last question would be with the front speakers having a 60 watt rms rating each and the rears being 100 watts rms whats my best bet for being able to give my rear speakers a little over 100 watts each without giving too much to the fronts? Or should i just use my deck to power the front speakers and use a 2 channel for the rears? Also i notice your from Washington also.

I agree with Chris, separate amp for the sub and for the other speakers..
