Yep, 80% is too high. At the most you would go up to 75% (3/4) of the way. However, how you tune an amp is...

1) Turn the gain on the amp all the way down to 0.
2) Turn up the headunit to the max listening level that you would use.
3) Slowly adjust the gain up until it starts cutting out or clipping.
4) Once you hit that point, you need to adjust it down a little from there.
5) Then you should be fine running at that level.

You can run a gain high as long as you do not turn up the headunit. When you turn up the volume, when the bass hits, it makes the amp overload which makes it cut off or go into protect mode. This will happen on all amps, no matter the brand.

As far as going to Kicker, you will not getting anything different. When power levels are equal, amps are pretty much the same when it comes to pushing a sub since clarity is not as much as an issue.

Ok got it! I guess I used to do this all the time and didn't have too many problems until I started buying newer amps. I really miss my orion 225hcca. Well, Im still looking at getting the Kicker zx650.4 or either a Boston Acoustics GT-42. The Boston acoustics seems to be 2ohm stable in brigded mode while the kicker is only 40hm stable when bridged. Im leaning towards the boston acoustics since its about $10 cheaper and puts out a little more power in bridged mode 400wrmsx2@2oms versus the Kicker at 325wrmsx2@4ohms. The only problem is I would have to run a 10'' sub that is dvc to get the 400wrms from the amp opposed to my old school 12'' solo-b that Is a single voice coil of 4 ohms.

You might want to check out JL Audio too. They are great because they put out the same power no matter what the ohm load.

Finally got everything resolved. Problem was user error! Sonic took about 3 weeks to get my amp back to me. I ended up locating a better ground and ran some extra grounds from the the battery to chassis and the alternator to chassis.

I rewired the the speakers to allow for balance. The tweeters sound great. Thanks DynamicSound! Ill probably send someone else your way soon for some tweeters or may come back and pick up some extra for myself.

I'm happy with the Zeus zxi 6406 and it has plenty of power for my needs. I now have the gains for the sub and the mids/highs at less then 40% mark! Thanks everyone for all the help.
