Your amp might now have enough power to push the subs or you need to get a better amp kit that will deliver the power the amp needs to operate at a high spl lvl

Speakers cutting in and out at high volume


The amp is going into protect on the two channels powering the speakers. Turn down the gain on those two channels. You also may want to consider crossing over the speakers a little higher than they are now.

The rating on those speakers are way too high. 6.5's and 6x9's will take 50-100 clean watts tops before they start to break up.

The best solution to get it perfect is....unplug the subs. Turn the gain on the speaker channels all the way down. Then turn up the deck 80% as high as it will go. Play a song. Then increase the gain on the amp until the speakers are as load as they go without distortion. Shut off the car, replugg in the subs and do the same thing. Gain on sub channels all the way down, deck then to 80%, find a bass heavy song, then turn gain up until subs become distorted. If you do this procedure your speakers and subs will be "gain matched" to the proper levels.

Good Luck

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

Sleuthing a 300/4 low-ohm issue. 300/4 amp history: unknown. just connected today whole system yesterday/today: head unit, 300/4(to 4 polk 6.5" component speakers brand new) 1000/1 (4-W3's),...


Are you sure you getting enough power to push everything. I have seen when the voltage is too low coming in, the amps will shut down so they don't overheat. Once they've cooled off and the volume level is lowered they will kick in again. Low voltage and a heavy draw will create massive amounts of heat.

I installed a Pioneer DEH-P800PRS head unit and 4 Kenwood KFC-1662S speakers in my 2003 Dodge Dakota extended cab truck. I used a Kenwood KAC-5204 2 channel amp connected in parallel. Sounds good at lower...


Hello.... sorry to hear about your problem. Bass is the ultimate evil of coaxial speakers. You have a couple of options here, and this is just my professional opinion because I do not know what your lifestyle details, such as truck space needs, type of music you listen to, budget, etc. If you are looking for alot of bass, the best bet would be to use 2 external amplifiers, 1 for the interior speakers, and 1 for a subwoofer. You would then need to purchase an electronic crossover. With this setup, you can remove all of the low frequencies from the coaxial speakers and put them where they belong, with the sub. You will gain EXCEPTIONAL clarity and a very high volume before distortion level. Again it will depend on what your budget is and if you are willing to compromise on some cab space. The only other option you have at this point is if you are wanting to play your music at high volume levels, you will just need to reduce the bass level as you increase volume. I hope this has helped. Good luck with your venture!!

My pioneer head unit cuts the audio signal to my speakers


3 things make sure all the speakers in the car have tape to avoid grounding the speakers
next make sure all wires in back of unit are taped

u should connect at least six 12" subwoofers (preferably 1000W each) to that pioneer amp of yours. Crank it up and enjoy. Your amp shouldn't cut off now. If it does cut off, you should change the fuse on your amp to a higher ampere.

No bass at higher volume


Your battery should be fine! Although the amp might not be strong enough for the sub. All you can do is check the RCA cables from your radio to your amp as these might vibrate loose when you get to 17 volume and also check the monster cable from your amp to your sub asit might have vibrated loose as well.
