Default Parallel power/bridge question.

I have an amp M4-3000D. If I run 4 speakers Bridged off the front channel. How much power can I expect. The speakers I am running are 100 RMS and 200 peak. Not looking for a firm answer because most amps inflate there power. But here are the specs for my amp. Thanks.

For one thing, the power scale is extremely exaggerated on this amp. And two, to bridge 4 speakers on the front channels they'd have to be paralleled and each be 8ohms.

So when I started this process. And I listed my equipment I was told I needed 4 ohm speakers? So you are saying it won't work with 4 ohm speakers? If I was to get another amp that would work. What am I looking for? Also as stated. ("Not looking for a firm answer because most amps inflate there power. " QUOTE. See link from past questions Thanks
So looking at the detailed specs I guess I would need a different amp. The two I have found that support full bridge fictions are:
PN4.-1000D and RZ4-3000D Any others I should consider? Thanks

According to the power acoustic website there are conflicting numbers.
Before you hook anything up and start throwing some power around I would suggest making a phone call to find out the proper ratings.

What speakers are u trying to feed? And why the obsession with bridging if u can parallel the 4 ohm speakers off the front and get a supposed 190 each at 2 ohm?

You can't bridge 4 4ohm speakers on the front channels. That puts your ohm load at 2ohms and the amp isn't stable to be bridged at 2ohms. I remember detailing the bridging aspect to you as 1 4ohm speaker across 2ch of the amp. In the end a 4ch amp will net you 2 4ohm speakers bridged. I would suggest doing as T mentioned and putting the speakers in parallel which would give the amp a 2ohm load but not bridged. That's a sister amp to the SS pn4.1000 so you should wind up with 125 watts per speaker in that configuration.

I used the wrong information. Thinking they were the same thing. It is parallel not bridged. I have never had to do that so while researching I spoke as if they are the same. As you have said they are not. With the amp I have I will be fine using parallel. As stated about 125 watts for each speaker. Received my PPS4-6 Rockford Fosgate mids too f'ng big for my pods. Magnet too big. Need a 1" riser. Thank you for all the help as always!
