I have a 2007 5.7L crewmax. I already have a CRUNCH PZT900.4 PZT-900.4(4 ohm: 115w x 4ch). I'm planning on adding a sub with either a Crunch PZT1100.2(4 ohm: 1100w x 1ch) or a sony xm-zzr3301(4 ohm: 600w x 1 ch).
My question is will this burn up my alternator or dim my lights? Truck seems fine with 4 channel amp i just put in. Do i need HO alt? Would a capacitor work in this situation? I really don't won't to spend $400 for a new altenator, if i don't have to. Thx.

I'm not familiar with Crunch brand, is it a true 1100 watts? Depending on how much power it actually pulls, you might get away with a good capacitor.
