[QUOTE="hispls, post: 8739761, member: 614752"] IF you're planning to use this for music most of the time, it won't matter all that much, but if they use clamped power as you run you could very easily buy a 2K or 3K amp and just dial in your gain at a specific volume level so that you consistently measure just shy of the maximum allowable power when you're actually up on the meter. If they're not going by what's printed on the amp or in the owner's manual may as well go big, much easier to turn it down if you're clamping too high than getting more power once your amp is at maximum output. You will not know what your impedance is at any given frequency until everything is installed, doors and windows open as allowed, glove box, visor, and seats adjusted, etc. etc. and you actually measure whichever frequency real world real time. NOBODY can accurately predict this and there's little you can do to change the impedance once you've dialed in a good peak. [/QUOTE]
