the amp was from one of my friends because he owed me $50 so I did not spend a lot of money on it

I just picked up a Kenwood KAC-9152D mono amp so I have a little more power now I can do up 900 wattsX2 at 4 ohms with dual mono drive so my dubs wont handle it

That amp has 2x30A fuses.

60A * 14.4V = 846W

800 / 846 = 94.5% theoretical efficiency.

This would likely be closer to real-world output:

846 * 70% = 590ish Wrms

Can anyone confirm this?

from my understanding it takes about 130% of the fuses capacity to blow on a dynamic load. Which really is just the rms figure..

So its really hard to judge by fuse capacity. Some manufactures might overrate their fuses and risk it and others wont. plus ~95% efficiency? give me 10 of them please. lol. 75% sounds more like it.

Alrighty, that can be quickly calculated:

846 * 1.3 = 1100W

1100W * 0.75 = 825W rms.

So that Kenwood amp can be expected to put out close to it's 900w rms rating?

oh and just to anwser your question about the profile amp before. When you wire to subs into 8 ohms each and then bridge them to the amp that makes the amp see a 4 ohm load. so now as that 480 watts goes out at 4 ohms it gets split between the 2 subs.
