Try getting some elctronic contact cleaner and then spray it into the controls and work it in for a few minutes on each control. Do this with the amplifier off, and after you have done this you can cheeck to see if it helps. If it does not help, you may have some broken solder connections on the controls where they connect to the board. That is something that would need to be checked by a service center and if that is the only problem it can be repaired for a very reasonable price, depending on the rates of the service center. If it is anything more than that, you may want to consider just replacing the amplifier, but that is something to determain after you find out exactly what the problem is.

There is just no way to know exactly what the problem is without being able to test the amp myself, but the advice given would at least be something you can do yourself and possibly fix your problem with spending too much money.

let me know if I can help you any more, I have been repairing car and home audio equipment for almost 18 years and have seen just about everything at one time or another.

Good luck,

Dave

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 good...be 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)...so I try to not use it much....

I have 2 12in kenwoods and a 1200 watt pyrimade amp, how can i hook these up to be the loudest


1st have your subs facing inwards towards the front of the car, not facing out the boot, This creates a better bass.

Wire 1 sub to one channel and the other sub to the other channel.

Turn down your gain as low as possible and then power everything up.

turn volume to desired loudness and then start turning up the gain slowly, if distorts a little turn in back down a notch.

avoid using bass boost, I agree it sounds great but it puts more strain on your amp and shortens its life.

after sorting out your gain, tweak all others until sound is bassy and clear with no distortion.

If you would like to use bass boost, turn on bass boost first, then up your gain etc.

Firstly, you will want to set all options to a low pass, so the high frequencies are filtered away from the subs, avoiding damaging the voice coil. Start with the Gain of the amp about 3/4 of the way up, and all other knobs, such as the bass knob to the lowest setting. From there, test your subs for soujnd, and then change the gain and amount of bass for the sound you desire, since each person is different. I have my gain about 1/2 way up and the bass about 1/4 of the way up. If you have a crossover knob, set it to the highest frequency available, since the low pass will filter all the high frequencies out anyway.

Amplifiers GT Series GT5-A604 ........explain settings


the amp probably has a x-over knob, a bass boost knob, and an eq knob. the eq is probably an internal crossover switch that will take the output from either high range (tweeters) or full range (6x9s) or low pass (subs) leave it on low pass. the bass boost however, will add distortion if turned up too high. its not noticable in the car, actually it sounds louder in the car but if you open the trunk and listen, you can tell its distorted bass and actually frying your speakers. the x-over knob is used to tune the frequency at which the amp stops pushing out bass tones. if you like rock music loud, turn it up higher, if you like low deep rap bass, turn it lower. keeping it too high might give you bad sound from either type though. ALSO THE GAIN OR LEVEL.IT IS NOT TO MAKE YOUR SUBS LOUDER IT WILL BLOW THEM .the gain is used to set your amp to your head unit which there is a procedure to do it.

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.

I plugged int he rca's but he the lowest sounding bass possibe


kicker subs arnt ment to hit the lowest bass, unless you go spend a **** load of money, im talking 3000 wat amp, ant some 15' or bigger subs. the most commen kickers are 12' subs, so im asuming you have 12' subs, if not, this (said lightly) should work. try turning the bass boost screw on the amp to the middle of its turning range. this will offer the greatest balance between high and low bass. if you want more low bass, turn it past half. if you want more high bass, turn it down. i have mine set to mid range, but i also recently purchased 2 18' kickers. with every new set of subs, you should spend at least 15 min tuning the amp to get the best performance. every sub is different. hope this helps, good luck.

Bass boost/Gain


Both the bass boost and the gain generally do the same thing, except the bass boost is essentially "additional gain" at a particular frequency (in this case, 45Hz). I would suggest lowering the bass boost (10?) and adjust the gain. Honestly, you may have to play around with both settings until you find a happy medium. There is going to be a maximum the amp can provide no matter how you get there. Hope that helps!
