Unless I'm still asleep, that's a mono amp. Mono amps cannot be bridged. You can use whatever positive and negative terminals you'd like.

Yup. On the amp it should have the two labeled on how to bridge it

so i will get full power of the amp if i use either channel?

Yes, well technically there is only 1 channel just 4 inputs.

yeah, arent they connected together? like aq1200d.. so you can use more wire to distribute all the amperage..

if amp is 1 channel. why do they make 2 outputs on the amp a left and a right?

Are they labeled left and right, or is there just two outputs? Also, are the inputs labeled left and right?

Just found a pic of one. Outputs are not labeled left and right

It's a mono amp with one channel. Wire it up as we mentioned.

I'm sure theres a good reason for this. Can't think of one though, outside of for the sake of RCAs

 

[Eddie Jones]

you are exactly right looked at it and only the inputs are labeled. what would happen if I connect one set of those outputs to a side of the r2d2, and the other output to the other side of the sub?

Bad things. Don't do it. I'm sorry but you need to ditch the sub or the amp.

unless you keep the gain turned all the way down it will likely cook that sub or the amp.

how ever if you wire the sub in series and then to the amp it will play just fine you just wont get a lot of power out of it.

I am going to wire the sub in series and get 4 ohms at the terminal. that amp is 275w at 4ohm x 1 so is that about 140 watts per sub? i also plan to add 1 more wired in series so that will drop the amp to 2 ohms.

they do it that way so it can be easier to wire up...its only 1 channel...so use a + and - and it will be ok
