HI all, I am new when it comes to messing with 4 channel Amplifiers and right now I have no idea what to do, if I even have an extra wiring option.

Ok, so here is what I am working with. I have a Pyle PLAM1600 1600-watt 4-channel Bridgeable Amplifier and I have 2 Kicker CVR 15" 2ohm DVC's. I was just wondering if my only wiring option is to bridge one speaker's negative and positive to channel 1 and 2, and the other to 3 and 4, which is supposed to make the amp see a 2 ohm load Or if I could maybe do another wiring option to maybe possibly give me more power. Now from the amp's manual:

Tri-way configuration:4/3/2 channels

4 x 400watts total output at 4 ohms

1600 watts total system output at 4 ohms

Mosfet pulse width modulated power supply

2 ohm stereo stable

Was just wondering if I could do Option 2 (not likely I do not think) or maybe Option 3 of https://www.the12volt.com/caraudio/woofer_configurations.asp?Q=2&I=22 to get more power out of this amp and to my speakers.

Right now I am very displeased with the power output of this amp. My old school Rockford Fosgate 360 watt amp I had that I blew by stupidity produced more power than this. lol I am beginning to think I might just need to get a new amp. Any help will be appreciated, thanks.

The only safe way to connect those woofers to that amp is option number 3. What happened to the Rockford amp? Did you already throw it away? What model is the Rockford?

Ok thanks, I was thinking that would be my only other "safe" option.

I still have the Rockford amp, it was a Rockford Fosgate Punch 360a2. Just 2 little capacitors blew. Nothing terrible to replace. The only problem with this tiny amp is it would overheat within like 10 minutes of high volume. And this is actually why it is blown I was stupid and plugged 2 12volt computer looking fans (which kept it cool) into the amps power and ground and eventually it didn't like that. Like I said blown by stupidity I wished I would have just hooked it up to different power and ground haha. But that's what I'm here for to learn :)

DId the capacitors just vent, or did they explode? Where are they located? Can you read the value and the voltage off of them?

DId you ever have the cover off of the amp and adjust the 2 controls inside the amp? If you did not do that, DO NOT.

Well looks to me that one exploded and the one right beside it might have just vented. I've took a pic but not got it uploaded yet.

And the numbers I could pull off were: NL904 M MTP 5()N()6V

If I could find a replacement it would be easy as that and have good bump again lol.

Thanks for your help man :)

That is a transistor. A capacitor is a small can with plastic wrapped around it. The power supply has failed in your amp. Chances are there are shorted output transistors that caused this. Not as easy to repair as capacitors.

Oh, ok then. I kinda didn't think they were capacitors but couldn't think of the other name for them Honestly was unsure. Is there a place you can find one of these transistors over the internet? I know why they blew in the first place and maybe can get lucky by replacing them and the amp will work again hopefully.

It is highly unlikely that just replacing the transistors will make the amp work again. You can find a suitable transistor at Mouser or Digi-Key. An IRF-Z44 will be the easiest to obtain.

So I should look for a IRF-Z44 transistor to replace with then?

Thanks
