Amp overheating and adjusting gain and frequency

Ok i have a rf p5002 amp with a single kicker L7 and my amp keeps overheating. Im not to tech smart with this subject right now, but i have some knowledge. I just want know how to stop it from overheating. My ground wire and b+ wires seem to be hooked up fine...i also really dont have access to volt meters and all of that so i would like to have the simplest solution first. also i heard it might be my gain and frequency adjustments, what would be the best settings for that? Thanks

Overheating in amplifiers is often caused by a speaker load of too low impedance. If your L7 is a dual 4-ohm voice coil, and if you're using the amplifier in bridged mode, that may be causing your problem. Dual 4-ohm subs, with the voice coils wired in parallel, present a 2-ohm load to the amp. Your amp is capable of running a 2 ohm load in 2-channel mode, but not bridged mode. The best fix with your equipment would be to re-wire the sub's voice coils in series, resulting in an 8-ohm load. The amplifier's power output will drop sharply, but you won't have problems with overheating in that configuration. There's a good chance that you'll still be able to get all the volume you want, even with an 8-ohm setup; otherwise you'll probably want to switch to a mono amp designed for a 2-ohm load.

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

Make sure your frequency is no higher than 80 on the low and 120 on the high. Check speaker polarity with a AA battery(Speaker pops out when polarity is correct) Make sure the speaker crossovers are working properly. Check your ohm load when you connect the speakers together with a multimeter at the amp. Ohms that are too low = heat. See what your amp is rated for. After all that, turn the gain down all the way, turn up the volume to 25-28 and readjust the gains

@aol.comI have a kicker zx 1500.1 amplifier and a 15 inch L7 2ohms. Is the amp too much for it?


the amplifier is never to much for the sub. If the gain on the amp is turned up to much then that will pop the sub.

Got a 12"kicker L74ohm sub and sony xm-D9001GTR mono amp


Hello juan_penaloz,

The Kicker L7 has an RMS power range of from 50-750 watts and a maximum power handling capability of 1,500 watts so your Sony amp will power it OK. A more powerful monoblock like the Alpine MRP-M1000 or the Kicker 08ZX750.1 would provide even more power and could operate safely at 2ohms.

You have the voice coils wired properly for the Sony amp. It's OK to have the sub impedance higher, but you definitely do not want it lower than the 4ohms the amp is rated at in bridged mode.

Hope this helps.

What Amp would i need to push three Kicker L7 12's?


Hello,

It depends on the specific subs and exactly what you want out of them. You have practically unlimited choices for amps.

The 10" L7 has a power range of from 30-600 watts RMS, the 12" from 50-750 watts, and the 15" from 100-1000 watts.

So if you have the 10's, you would want an amp that puts out at least 90 watts RMS and not more that 1,800. Unless you are really into SPL and have an unlimited budget, it's probably best to go somewhere in between.

Keep in mind that these Kickers need to be in a proper enclosure. They like a little more volume to work as compared to RF's or MTX's and some others.

So you have to run both of the subs to your amp so that its see's 2ohms. The L7's probably have to voice coils to connect both the positive's together and both the negatives together to the positive and negative on your amp
