Im totally confused n where to put the settings on this amp and i just want some straight forward help please?


Your SX650.1 is 2 ohm stable so wire the voice coils in parallel and the speakers in series, then bridge the amp. Keep your multimeter close. Don't forget to beef up your input wire size to 4 gauge on the positive and the negative side. The rear channel should be set around 80 Hz. Your amp has a variable low pass crossover (30-200 Hz) with adjustable slope (set at 12/18 to start) but you should be able to hear the bang and the boom in the sub woofer. This is only a starting point for the real ear tune. I turn the gains all the way down and give the head unit 3/4 volume, turn the gains up just before it starts to scream then fine tune the frequency (Hz). Do the front and rear separately by disconnecting the RCA's, and then together. Try and play a wide verity of music while your adjusting your amps, but fine tune what you like. I hope this helps to get you started, Ray

I have a clarion m 309 radio and I'm trying to hook up a fusion FM 402 amp for a sub woofer. I had all speakers playing but, I could not control the volume of the sub with the radio. I need to know...


Amps usually receive their signal through RCA wires. Your radio should have one pair of RCA outputs on the back. (red and white) You will adjust your subwoofer volume by adjusting the gains on the amplifer (little knob next to the RCA inputs of the amp), then you can turn up the bass on your radio.

How do i get the best sound from my infinity 1250w subwoofers


Make sure the ohm's are the same on all your speakers and amp.
You amp watt should be equal or higher then your speakers total amps.
You base box should be completely air tight, and have about 1/2 of the box stuffed with cotton.
Make sure you use a good thick speaker cables to connect from the amp to the speakers.
and finally, make sure your trunk seals tight and wont rattle... cause nothing sounds worse then someone pulling next to you and all you hear is a buzzing sound from the trunk rattling... Also... sell the infinity's and get something like memphis, or panasonics. :P

Someone gave me amp, dont know how to adjust it


What kind of amp is it? This will help with proper setup. 1st turn down the gain on the amp. 2nd if the amp has a crossover determine if you want high pass or low pass. There may be a switch and a knob with markings like Hz 40-100 ect.. with the gain down turn the volume up on your radio 3/4 of the way up. Now slowly turn up the gain till you hear distortion and back it down a little. Sit back and enjoy :D

There is no "perfect" setting that can be placed in a manual. It's all done by ear. Your settings will vary depending on the vehicle you are in, the type of enclosure you have, the type of music you listen too, how much voltage your deck put's out. There are many variables, but I can try to give you a basic guide.

First of all you need to know your enclosure. If you have a ported enclosure tuned in the mid to low 30's you may want to set the low pass to around 70-80 hz with your sub sonic set at 30 hz. this will give you the higher bass frequency you need for the loud bass you want, and protect the sub from going too far below the tuned frequency of the enclosure, and losing it's composure.

As far as the gain, and bass boost are concerned, you just have to adjust them by ear. First adjust the radio volume to normal listening levels, by that I mean as loud as it can go without the speakers in the car sounding like ****. Now you adjust the gain first. slow turn the gain control, carefuly watching and listening to the sub.. Adjust the gain to the point of the woofer getting a lil sloppy then back it down a bit until the sound is clean again. Now do the same with the bass boost. if there is a bass boost frequency adjustment, set that as close to the tuned frequency of the box as you can.

If you are in a sealed box the adjustments are a bit easier, and are all about taste. Adjust the radio as described before, and put on your favorite song. Next start udjust thing lowpass frequency to taste, not too high tho, try not us higher than 100 hz in your sub's for better sound. Sub sonic is not quite as important in a sealed box, as there is much less danger of the sub losing control.

Well good luck, and hope this helps!
