Mono split to stereo?

[cbrrocketrdr 10+ year member]

I have an Audiobahn A8000T...its a MONO channel amp.

specs are:

400 watts RMS @ 4ohm load

800 watts RMS @ 2ohm load

now I have a Treo Engineering 15" sub...its a DVC 2ohm...now technically im only allowed to wire the sub to a 4ohm load for the amp to read. but id like to get 800rms...now here's my question. can i run 2 positive wires from the amp positive to each positive coil on the sub and 2 negative wires from the amp negative to each negative coil? my theory is it would still read a 2ohm load and since both coils are hooked up it would split the power, thus putting 400rms to EACH COIL/ 800RMS total to the subwoofer....any input on this? if not possible no biggy i have a DVC 4ohm sub on the way that i can wire to 2ohm load but i wanted to run my treo in the mean time.

In a word, to answer your question, No.

What you're talking about is known as wiring the coils in parallel (wiring both positive coil inputs to a single positive amp output then likewise for the negatives) and will show the amp a nominal load of 1 Ohm when using a DVC 2 Ohm driver.

Best case scenario is that you'll throw the amp into protection.

Worst case scenario is that you'll damage the amp by showing it too low of a resistance.

No, running extra wires to the same terminals isn't going to do anything for you. Just wait for your new sub to arrive.

Here's what you're suggesting doing and this diagram plainly illustrates the result:

alright people thanks for clearing that up...i was almost sure it would be a 1ohm load bc whether i ran + to + on the sub then to the amp or ran 2 wires directly to each + it would prob be the 1ohm load but i wanted to be sure...thanks forum help!
