What would be te best amp setup?

Answer 1

You should use two separate amps. Running an amp in tri-mode which allows for one stereo channel and one mono channel, will not make enough power for the subs to run full force.



You need a stereo amp for your mids. Look for something 4 X 50 watts RMS. That will be plenty for 6 x 9's. It will sound really clean cause you wont need to crank the amp.



Run your subs in Mono if you can, and bridge an amp to mono so you get the most output possible, and the subs are hitting evenly. Runnin subs in stereo results in cancellation of sound since the subs are not moving in sync.



You really need to include the resistancein ohms of your subs. If they are dual voice coil list that.

Answer 2

As far as wattage, matching the watts RMS is best as is the impedance (ohms) for the load to the amp.



Be sure you use the right guage wire with fuse blocks to prevent fires and deliver enough power. If your headlights dim with the music or you don't get bass with enough "punch" to it, consider an alternator upgrade.



A cap is only good so far as the audio system isn't trying to pull too much from the electrical system. A cap doesn't provide more power, it's designed to 'stiffen' the voltage to the amp, nothing esle. If the current isn't there, a cap won't help.



If your total system power is a 1000 watts RMS or more you will need to:



1. Upgrade the alternator to a high output alternator

2. Upgrade to a heavy duty deep cycle battery

3. Upgrade the "Big 3" - that is to replace the power wire between the battery and alternator, the ground from the battery to the chassis and the ground strap from the engine/tranny to the chassis with at least 1/0 AWG wire.



Failure to do this will result in you replacing them anyway as the alternator will eventually fail.



Here is a guide that will calculate what size alternator and power wires you need as well how to set the gain http://www.datafilehost.com/download.php?file=6d26c621



You'll need Microsft Excel to use it.

Answer 3

You'll get better stereo separation, clarity, and bass the more you split it up. I would do a 4-channel amplifier for the 6x9's. It won't take up much more space than a 2-channel amp, and you'll be able to have front/rear fade. Use an active crossover to send only the mid & higher frequencies to these (nothing below 80hz). Then, use a separate 2-channel amp for the subs. Stereo separation isn't important for the subs and nicer amps will let you bridge the channels and run the subs in parallel off that. You'll have to look at the ratings of the amps and subs to make sure your impedence doesn't get too low for the amp to handle if you think about doing that. If in doubt, just leave it 2-channel and run one sub off each channel. Again, the crossover will come into play here. I wouldn't send anything above 150hz to the subs, but you'll have to play around with the crossover points to see where your results are best in your truck.



As far as wattage, the more power the better. Don't worry, you'll only blow out those Alpines if you send too much bass or unclean power, or if you really crank it up way too high. In that case you are either trying to win a competition or you've just blown out your eardrums - congratulations.



Be sure you use the right guage wire with fuse blocks to prevent fires and deliver enough power. If your headlights dim with the music or you don't get bass with enough "punch" to it, consider installing capacitors for the amp the subs are connected to.



[edit] True, a good working alternator and battery are important to a good system. But getting too big of an alternator saps your car's power and mileage for having to run it, and it still won't solve all your problems. The path of least resistance will be your high-quality power cables running to your amps, so then your battery and alternator still limit you. A capacitor stores energy by definition, so it will be able to provide power for the bass when needed. They can deplete their power with big enough bursts, but they'll give you punchier bass and save your battery and alternator from unnecessary wear.
