Amps making whining noise when strapped.

Recommended Posts

I ordered 2 pure 1500 monoblock amps a month ago. I finally got around to hooking them up in my expedition. Every time I bridge them, they make a low whine noise. When I unbridge them and run them solo there is no whine. I had brutus's strapped before without this problem. I have 2 runs of 0 gauge from starter battery (which is a duralast platinum agm battery) to my xspower agm battery. 1 run negative and 1 positive. I have a 270 singer alt. All my grounds are fine. Do I need a special patch cable to bridge them?

N8 that would be correct. $500 to you sir!!

seems like he has all the right gear but then went cheap on the amp.

Thats cool. Im way too old to be upset by shit like that. Your name is winston. Your own parents hated you even before you were born.

My penis is bigger than your penis

I'm far from loud and my roof/headliner flaps around like Adam's ass on a windy day. I think it depends more on the structure of the vehicle.

So it is the amp. I had some brutus's before that and they didn't whine. As a matter of fact, The pure amps sound better and seem to hit hard. Oh well, when I bought the pure amps they were 135 a piece, now they are 275 so I should be able to sell them for more than I paid and I still got the brutus's so maybe I will hook them back up until I find a decent price on a used sundown.
