Im looking for some help on how to build a good system curently i have 2 12's that are Rockford Punch XLC's with a Farenheit by Power Acoustik amp that is Q2-1500 watt max also say HPF/LPF and 2 ohm stable i have no idea what those things mean a little help would be appriceated! and is that a good setup? its a ported box with tweeters
thx

 

Assuming you mean you are stuck on the amp specs...


1500w max means that the most power your amp will produce at any one time is 1500w. This may only be at a specific frequency, with a specific signal strength going to the amp through RCA and with a specific voltage powering the amp in a controlled test environment for one second, but it is the most it will produce.

There should be an RMS value somewhere in the user manual, this is the nominal or constant guaranteed output the amp will have, and it is a much more accurate definition of the amp's power output. Usually it is about 1/2 to 3/4 of the max output the amp is rated at.

HPF/LPF (High Pass Filter/Low Pass Filter) means the amp is equiped with a crossover circuit. It can be set to let any frequency above a givin frequency through to the speaker(s) or, and frequency below a givin frequency through to the speaker(s). This is very important when using subs, as you want as few highs as possible going to the sub. Whereas with a highpass you can stop lower frequencies from getting to smaller speakers that do not respond well to them and therefore prevent or at least minimize distortion.

Your amp being 2 ohm stable means that it can safely run with a load of no lower than 2 ohms. This means you can connect speakers with a 2 ohm impedance to your amp.

Or you can bridge the left and right channels to make a 4 phm speaker appear as a 2 ohm load on the amp.
