Question about Kenwood Car Audio & Video
SOURCE: adjusting wattage on kenwood kac 9103 class D mono amp
That amplifier is 900W x 1 @ 2ohms.
If your subs are 4ohm SVC wired Parallel, resulting in a 2 ohm load, each sub will only see 1/2 of the rated power. (450W ea.)
Your gain (sensitivity) setting should be between 75% and 85% to max. You will be fine.

I'm using that Alpine right now for 2-12" subs and I have compared it to 6 or 7 other amps this month and most were 4 channel 150Watt/Channel Bridged to 300Watts x 2 and found the Alpine to be superior in both sound quality and loudness. The Alpine has also not turned off even with full volume for hours at a time, Very solid amp I was very surprised due to it's size!

The sub Thatcher's with the JBL sub box amp combo wasn't I dont think anyways. But the Rockford Fosgate Punch P3 dose have dual voice coils.
Run one amp bridged with one voicecoil and the amp with other coil.
