Looks like mb quart fails

Two channels bro they both end up bridged inside...Yeah I'm young an ghey because I got a defective amp... Makes sense

RCAs in the in
Wrong, its a single channel with an extra positive and negitive teminal as a convinence so you dont have to try and cram heavy gauge wires into only one set.

Also I have delt with Sonix on this same deal with the same amplifier with these same issues just get your RMA and get another one I ended up getting one that worked well and the buyer who has it still beating up on it.

You have options if you have money you can buy another one with there buy back return deal, you buy the replacement then once they get the RMA return and tested as defective they credit you the 209.99 or what ever you spent on it.

They did this for me and I never had to pay a 10% restocking fee, that only applies if you are returning the amp if you dont like it/wrong product, not for a DOA product that neither you or them have ANY way of knowing, charging a 10% restocking fee on defective DOA items like that would put them right out of business.

FYI had 2 1500d from them DOA 3rd time was a charm.

Extra channel bro.... They are hooked together inside (bridged).

 
My amp has the same setup.. however its still a mono amp.. just the two - and two + leads are connected togeather on the inside.. its still a mono amp.. not a 2 ch.

just depends on how you look at it

 
You are wrong. It is a MONO amp, ONE CHANNEL. It just has 2 terminals that are paralleled internally. Nothing is bridged
x2 the OP doesn't understand the term "bridging", the extra set of terminals exist only for ease of install. "Bridging" is when you take a 2 channel amp and sum the two outputs together into one. Your MB Quart is a MONO, 1 channel amp so "bridging" doesn't apply.

...at least the OP isn't as bad as a friend of mine who doesn't understand dual voice coil.

My friends are the same. Wiring a pair of subs together is completely beyond their comprehension.

They all want stereos, but none of them are willing to learn how to install anything. And giving them endless free tech support is a pain in the ass...

 
It ended up being my 4 year old pioneer 1900mp the outputs went bad
Just bought a pioneer 3200ub and two American bass xfl 15s
That's kinda odd cuz when I hooked up a brand new MB Quart DSC-480 the outputs on my CDA-9887 went bad for the speakers..
