How do i hook up the crossover to the amp?I see how to go from the cross over to the spk, but dont know how to come out of the amp to the crossover?

Crossovers separate high and low frequencies for routing to the appropriate speakers.

When I used to do this, I would run the power wire from the battery to the Capacitor and then run power wires to said amp. For the crossover, just run an 16 or 18ga wire to one of the Amps power input instead of running it to the cap if its easier. Not sure what Crossover you have, So check the manual for the correct wire size!

Your basic crossover is going to have a power (+) and ground (-). Your power wire goes to the battery, and your ground goes to the frame. You will need to hook up your RCA or speaker wires to the input side. Then hook the other two RCA connections to your amp.

Yes you Can. run them bridged parallel. meaning on the amp where the speaker wires attach there should be labeled with a "+" and "-" with a line drawn to show which terminals to hook the bridge wires up to. bridging takes power from both sides of the amp and puts it into one strong signal on half the wires. from there run your "+" wire to the first "+" on your first speaker. run your second wire from "+" on spk 1 to "+" on spk 2. repeat process from "-" on amp to "-" on first speaker and then to second speaker. __ ' a'"+"________"+"_______+ Good luck, may the force
/ ' 'm'"-" spk spk be with you!
bridged \ '__ ' '"-" ________"-"_______"-"

this will get you the most sound from the amp. if using 4 ohms speakere you will be running a 2 ohm load bridged.

you dont have to have a crossover to hook up ur amp 2 ur subs

The B+ terminal on the amp goes to the Positive battery terminal with a fuse inline probably at least 60amp for this amp. The GND terminal of the amp goes directly to the chassis of the vehicle (metal) and try to keep the ground 18" or under. The REM terminal of the amp goes to the remote turn on wire from your deck, usually the BLUE wire. Some decks have 2 one for an amp one for a electric antenna. Dont hook it to the power antenna wire or your amp will only work when the radio is on. Won't work with the cd player. Hook the left and right inputs (rca) to your source unit (deck). Hook your speakers to the left and right channels of the amp with the correct polarity (+) (-) . Set the cross over on the amp HP-AP-LP for what ever application you are using it for like subs or components. There is a frequency adjustment for the crossover on the opposite side of the amp. This should be set in accordance with your crossover selector and speaker requirements. The punch bass knob should only be used with a subwoofer application. The left and right gain turn up or down the gains of the amp. (power output) These are set depending on the output voltage of your preouts (RCA) on your deck. A small flat head screw driver can be used. Set them between 1/2 and 3/4 if you dont know but make sure they are the same. Your ready to go. Hope this helps.....

sound like you have a a bad spkr connect the spk one by one to amp and play the system and you will know and make sure the spk can handle the load from the amp too''

un plug rca
and disconnect all spk from amp and turn on if light dont come start with one rca at a time and one spk and connect and you will find the problem

that strange i dont know is some instruct you that way but wht you did has nothing to do with the spk the only think i can say if amp working fine re-tune system

connect speaker wiring for car to speaker wire side. plug the rca's into the amp ground the ground wire. run a live from the battery to the power on the crossover and run the remote wire to the blue (iso connector) wire coming from the back of the radio
