How should I wire these subs?

[drummin89]

I have a Kenwood KAC-9105D amplifier and 2 different sets (2 subs a set) of Pioneer dual voice coil subs. Set 1 has dual 2ohm voice coils and Set 2 has dual 4ohm voice coils.

These are the subs http://www.pioneerelectronics.com/PU...502D2|D4?tab=A

The amp is a mono amp. At 2ohm the watt output is 900 and at 4ohm its 500. The subs are rated for 800watt rms and 3000watt max, same for both sets.

Currently I have sub set 2 wired. I have the voice coils of each sub wired in series to get 8ohms per sub. Then I have the subs wired in parallel to get 4ohms final.

Any other possible ways to wire these subs to the amp? Which subs should I use and how should I wire them?

Heres another question. The subs are rated for 800watt rms and the amp at 2ohms is rated for 900watt rms. Will I without a doubt damage the subs if I wire the subs in a way to get 2ohms final?

I was thinking of putting in sub set 1. I would wire the dual voice coils for each sub in series to get 4ohms per sub, and then wire the subs in parallel to get 2ohms final. But I don't want to do this if I will damage the subs.

Thanks!

I've installed a few basic systems before but never really dealt with multiple dual voice coil subs wired to a mono amp. With all the numbers my head starts spinning after a while.
