Two important questions!

[Raging.waters]

1) i currently have an alpine mrp-m350 amp and im considering upgrading to a kenwood kac-500.1. My two subs are 12" mtx thunder 5500. The alpine putts out 200 watts in 4 ohm and 350 in 2 ohm. The Kenwood puts out 300 in 4 ohm and 500 in 2 ohm. The mtx's are 150-300 at 4 ohm. (These are all RMS ratings).

What I'm asking is will upgrading from my alpine to the Kenwood give a noticeable change? Like sub's already hit hard but would running the Kenwood make them run better?

2) my 4 channel amp is shipped and coming in about a week. Since I know how I will set the gain, with my new amps, what should my hz on the mono and 4 channel be set to? I heard 80 hz is good/universal for mono amps but what about my 4 channel? Like what do yal suggest I start around? 80 hz as well but just turn on the high pass filter?

Unless you really know your car you won't notice it.

What exactly do you mean?

Going from 350 to 500 is the same as going up 1 click on the volume knob. Those of us that know every detail about our car will notice it. Those that don't won't.

Ok thank you for that answer, what about my second question?

Can't say. It's up the the speakers, install, and what the car wants. 80 is a good start. Not all mids will work well that low.

Seeing as you're low passing the sub at 80, you'd want to high pass front stage there as well. (Safe bet) Some like a little overlap though,

No it don't need to be the same. The 2 slopes should work together to bring it up. If they are the same it will boost it
