The FX500 is 4 x 75 watts clean and 1 x 500 watts RMS @2 ohm mono. What subs are you running and what are the ohms per voice coil. Single or dual voice coil. By what you said (not getting hot) sounds to me like the load istoo much. Let me know.

I was/am a Cdence daler and I sold many of those amps without a problem Never had a bad one!

I have a power acoustik 0V4-1200 amp and 2-12" kicker cvr dual 2 ohms. My amp keeps getting really hot and turning off. I have two pair of rca jacks from my cd player to the amp. One speaker hooked up...

i have found the specs to your amp. 1. Amplifier connections: Lets make things simple. As we look at the amplifier speaker connections, we will number the outputs 1 2 3 4 from left to right for the top connections and again 5 6 7 8 from left to right for the bottom connections. 1 should be connected to a positive (RED) (+) on sub woofer A on voice coil (a) 4 should be connected to a negative (BLACK) (-) on sub woofer A on voice coil (b) Now using a small piece of cable, connect negative of voice coil (a) to positive of voice coil (b) Follow the same procedure for the other sub woofer using 5 and 8 as 1 and 4 This configuration should make the amp run at 4 OHM BRIDGED x 2. i hope this helps. dreamsystems

How can i test my rca output jacks with a test light? pioneer deh p3100ub. hooked up spkr, nothing. tried one rca plug to white(lt) and then red(rt). Unit has 4 rca jacks, 2 for subwfr and 2 for front...

:) the rca jacks have to be connected to an amplifier,, their signal is too lay to even light a bulb.. you have to connect it to a car amplifier and then from the amplifier to the speakers..

Just so you'd know,, once your deck plays and you hear music on your speakers through your normal speaker wires,, RCA jacks work..

Ok you have 4 jacks,, 2 subs and 2 front.. These should connect to a preamp,, which takes 4 inputs and allows you to equalize or adjust how the music should sound,, now from the pre-amp,, it runs to an amplifier,, thats powers the subs and another that powers the speakers.. Some amps have 4 inputs so you can use one amp for your subs mids and heights..

for example a basic music system is

1 cd player
1 pre amp
1 amplifier (4 inputs, 4 channel out)

you bridge 1+2 and connect this to 1 12" double coil sub woofer

the next 2 connect to 2 mid speakers example "rockford or ev 5 / 8 " and 2 tweeters for heights..

Thats a kicking tricked out basic car audio system,,,

Hope that helps you understand how it works..

I am wondering about car amplifiers, I don't know what kind to get, I have Alpine 6.5" 2-Way Car Speakers (SPS-600), 80 watt as my front speakers, and Alpine 6 1/2" 2-Way Car Speakers (SPR-17C), 100 watt...

I would strongly recommend that you get a 5 channel amp that puts out 75watts rms per channel that will deliver between 200-300 watts to the sub channel. I use planet audio amps myself and they run strong all day every day-maybe you could look at a planet audio vrx 600.5(5-channel) it throws 100w x4 and 200 or 300 to the subs depending on the resistance of the sub. Good luck

I have 2 6x9 speakers up front 4 6 1/2 3-ways

Hello rjmiller4039,

Although amps with 5 channels are pretty rare, you can get one. Alpine, Boston Acoustics, Infinity, JL audio, MTX, and Polk all have 5-channels ranging in price from around $350 up to around $1,000. The Alpine PDX-5 will output 75X4 watts RMS for the front and rear stereo channels and 300 watts to the mono sub channel. It is priced at $599.99 at Crutchfield.

Hope this helps.

What is the best way to connect 4 speakers and a sub to a 4 channel amp.

I would connect the 4 speakers to channels 1-2 in stereo with high pass filter. Bridge the sub to channels 3-4.
A thumbs up would be greatly appreciated if this answer is helpful to you. best-way-connect-4-speakers-sub-4-zb4bomd1rt4qms0dqd12kkt2-3-0.jpg

Alpine type-r 2ohm dual voice coil help

try reconnecting your rca's from the deck to the amp when finished wire one speaker positive to positive on left channel and negative to negative on right channel then connect the 1st subwoofer. if all power and sound is fine and working turn off power to amp and connect negative terminal of 1st sub to positive on 2nd sub and positive from first sub to negative on second crossing the wires runs the speakers in series another way to try is parralel the speakers wiring by connecting positive left channel output of amp to positive on 1st sub same with the negative then splice positive to positive on second sub and same with negative.

How many speakers can I use?

This should work if channel 3 & 4 are bridged at 4 ohm.
channel 1 should be stable at 2ohm
channel 2 should be stable at 2 ohm
You can hook up the right side speakers together ( + with + and - with - ) . same thing with the left side. this will give you 2 ohm each channel. this will cause your amp to run hot (this might be tuff on the amp). It will give you right (2 speakers) and left ( 2 speakers ), no front and rear adjustement if you need to balance your sound. I think you should be better buying another amp for your sub and take your 4 channels for your 4 car speakers. this amp as a rca output that can feed the other amp ( sub amp ). it is possible to do it.

Good luck

I hooked up a 4 ch alpine amp MRP-F600. The back speakers play nice but the front speakers play very low. What could be the Problem?

1)When you connected the amp to the head unit, did you run two pairs of RCA cables for front and rear reference or did you only run one set of RCA cables from the rear out to the amp?  2)If that's not the case and you did ran two sets, on your amp, swop the rear and front RCA cables. If the rears go quiet and the fronts are loud you now know the issue is either in the cables or how the head unit is set up. If the fronts are still quiet, check your Amp's gain, frequency and filter setter settings (if available). If those settings don't change anything you may have a faulty amp. 3)Check speaker connections, seems trivial, but you never know.
Message me back if nothing works and/or you get stuck.
