efficient amps and hybrid car?

[haydenlake 0]

Although I'm not worried about buying an amp with enough power (bc I buy quality gear) I'm still unsure how efficient an amp really is.

My really old PPI PC 2150 A/B class says in the manual something like 70% efficient which is better than many class d amps now (I read something about the JL 500/1 being about 50% effiencent.)

Anyone really know how efficient their amp is or how I can find out without buying one?

PS I have a 06 Toyota Highbrid and I'm thinking that the normal 12v system is going to get taxed pretty hard with a moderate system in there.

My system will be

pair of 6.5's up front (likely XR's or Mpyre's) powered by my PPI PC2150

Single SS RLP 12 in a ported box (hopefully) but I want to converve space

Anyone know if the normal 12v electrical charges off of a typical alternator and goes straight to the 12v batt, or does the big alternator that charges the electric motor bat also charge the 12v batt. I would think this would make a huge difference. I really don't want to spend a bunch of money on a full on charging system and more bats

thanks in advance

Anyone have an ICE-power class D amp out yet? Them are crazy efficient.
