amp and sub combo

What would be the best way to wire these subs with this amp? Could i wire them to 4 ohms load to get a good sq? I have wiring diagrams to wire them to a 4 ohm load or 1 ohm load but dont know which one i would get the best sq out of. Im not looking for a ton of bass just good sq.

A 4 ohm load will be 4 times easier on your amp.  Wire it like that and if you have enough bass, then leave it that way.  If it is not enough bass you may have to wire them to 1 ohm.

Or you could do both:

If you are going for sq just go with the 4 ohm setting. I would think your system would be pretty unbalanced with 900 watts of bass unless you have your other speakers amplified. If you are just running your other speakers of your head unit then 500 watts of bass is more than enough.MECP Advanced

Hello Is that the pioneer Ts-308D4 ? Because I would like to install 2 like this one and I wonder which amp I should choose to be able to extract all the subwoofer power ? I saw some nice hifonics Hifonics HFi1500D Hifonics Brutus BRZ1200.1D Hifonics Brutus BRZ1700.1D Hifonics HFi1000D Thanks in advance guys lsd972

To the OP... I agree with everybody else. Go with 4-ohms, the amp will run cooler with less distortion, and your damping will be higher. You will also have less than a 3dB difference in output between the 4-ohm load, and the 1-ohm load.

Contradictions in terms, there, amigo. HiFonics USED to be close to OK, stuff. But now? Mid-range Swap-O-Rama gear, at best.
