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

Re: amp overheating and adjusting gain and frequency

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.

I have a kicker sx650 powering two kicker cvr 102 at 2ohms but i havve no clue on where to set the settings at and i know this amp should make these subs pound. i need to know exactly what to put each...

How I tune:
turn amp all way down or disconnect rcas for now, turn up stereo to a song with some bass you listen to and crank it as loud as you would (not max about 3/4, use this to tune inside speakers (don't have bass maxed/distortion...)). Now dial in amp: turn up a bit probably to 1/4 or so then tune frequency I'd usually say around 100hz, then adjust gain again to where it sounds easy on them for awhile to let them break in (don't blast them all day!). Usually bass boost is only 1 frequency with a curve (40hz or something) I try to not use it much....

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 kicker ix 500.4 hookd up to polk audio 6x9 and 6.5. if you play the system past about 25 volume the subs will keep playing but the speakers will cut out for a few seconds as if its hiting the

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

I have 2 kicker l7 12s 4ohm speakers and was

Hello gonenutz14,

It depends on how you define the "best way". Driving each sub with a separate 750 watt amp will result in about 50 percent more power than having them share the output from a single 1000 watt amp. But with 2 amps, there's more wiring issues to contend with and the adjustments are more complex. The 2 750 watt amps will cost more than a single 1000. Plus if the 1000 watt amp is stable to 1 ohm, the power difference will actually be less than 50 percent because of the lower impedance. But if the 750 watt amps are also stable to 1 ohm and their outputs can be combined, we're back to 2 being better than 1.

I'd say that the simplest, most economical way is to use a single amp. If maximum power to the subs is the highest priority, and cost and wiring is not an issue, then 2 is better.

Hope this helps.

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.

Kicker kx600.1 class D mono amp

This question really can't be answered accurately online for a few reasons.. we don't know if you have a ported or sealed box, we also don't know what kind of box you have, wether it's a 4th order, 6th order...blah blah blah. We also don't know what the box has been tuned to (if it's ported). unfortunately, you'll have to play around with it yourself or get someone to physically see your set up. But here are some tips to help you tune your set up.
1st set up the frequency( or crossover). this basically tells you sub the range it should run in. alot of people don't set up their crossovers properly and the sub is reproducing frequency's the mids are producing so some notes are far louder than they should, which makes for unbalanced audio. when you get that sorted out move onto the gain. (keep in mind, that if you've only installed a sub and have stock speakers or are running upgraded speakers off the head unit and not an amp the frequency is going to be harder to control since you can't control the other speakers.) next the gain, the gain is really just volume. Play a song with alot of bass and set the sub at a volume that pounds, but not to the point where your other speakers get drowned out and there you go, you should have a pretty good sounding setup. If this is the first time you're tuning it may take some time, but please do this with your car running, far to often i hear people killing their batteries as they don't realize that amps really do **** alot of power.
If you purchased the subs and box separately the box usually tells you what it's tuned to (if ported) and you can use that to guess where to set your frequency.

2006 12" Kicker L7 4 ohm

first whats the range in terms of WATTS that your 12" sub can handle in 4 OHMS ? second , lets check the AMP , POWER ACOUSTIK 1800 WATTS , Now thats a lot of power to drive a single 12" sub speaker . your amp is 1800 watts , per channel is around 500 watts , if BRIDGE thats around 1600 watts rms for ONE channel , if your sub can handle that kind of wattage fine , but it will not blow the amp , what it does is shuts down , some kind of protection mode , it will come back on after a minute or so. I suggest to use one channel in stereo mode , or purchase another sub to use the other channel. i hope this helps AJ
