Hey guys, new here and new to owning a prelude as well
So naturally I've got a few questions about a new sound system build I wanna put together.
All I'm going to do at the moment is install a new head unit (Kenwood KDC-BT562U), four new speakers (Polk db 6x9's and db 6.5 components) that all rms at 100w at four ohms, and an amp to push them at that wattage (Pioneer GM-D8604). Gonna install it in the trunk with a 4ga awg wire, and the 80a fuse that comes with the kit I'm looking at will be fine for the moment.
Now all that's fine. Obviously the alternator will be able to handle that (I mean the system's only 400 watts). But what I'm worried about is when I install subs, I'd like to push them with this amp, doing 800w at 2ohms...
The two amps are pushing speakers with different resistances, but combined isn't it still 1200w? I'm thinking that's a bit high for the stock alternator. Would a capacitor do the trick, or just larger power wires for the car, or a new alternator, or all three? I installed two amps in a Camaro I used to have but that car was beefier in general and I didn't really have to worry about anything.
Lastly, I want to run both amps on the single 4ga wire, given it's short enough. Just looking at the fuses on the amps it totals 180a, this a good fuse replacement?
Any other words of advice would be rad, thanks guys
