Honestly listen to it buy ear. Thats the best way to "tune" your amplifer and your subs. I would turn your stereo to the desired volume level then start tuning your amp while it's playing. Make sure that you put the signal all the way down to start with and if you want it louder, that the signal level (knob) is the last thing you turn up.

dissconect your speakers and check the resistance on them you may have blown them

If you know how to use a multimeter, you can test the amp this way:

-unhook the subs
-hook up a cheapie speaker you know for sure works to one of the channels
-unhook the audio inputs
-turn the amp on
-set your meter to VDC
-put the positive probe on the inside of the input connector, being sure you make contact with th inner contact
-take the negative probe and tap it on the outside of the connector

What you are doing is sending a low voltage (replicating an audio signal) into the amp audio circuit and allowing the amp to amplify it. If the amp makes the speaker pop each time you strike the probe, the amp is working.

There is an inherent problem with band passes. The naturally filter out high frequencies like a crossover, including distortion, so it makes it hard to hear when the subs begin to protest.

I wouldn't, you need an amp that can support a 1.1 ohm load. I don't know of any head unit onboard amp that can!

Hi Robert, whenever you put two or more speakers in parallel, the power handling must be equal in each speaker and the sum total of the power of the speakers, must be greater than the power of the amplifier, to avoid breakages due to excesses of power
I hope my comment has served you
Greetings Franco Dosil

Hola Robert, siempre que pongas dos o mas parlantes en paralelo, el manejo de potencia debe ser igual en cada parlante y la suma total de la potencia de los parlante, tiene que ser mayor a la potencia del amplificador, para evitar roturas por excesos de potencia
Espero te haya servido mi comentario

Check all wiring/connections, fuses, etc. and don't forget the one on the back of the deck itself!
