Speaker type The speaker is KFC-W1212DVC and the amp is KAC-X520....I also wanted to know, I have a 760W Pioneer amp...will that work better than the 1000W Kenwood KAC-X520...

pioneer gm 6500 is a 4 ch amp rated at 60w-4 way to small of an amp to run your sub. UNDER-POWERING your sub is more likely to damage spkr than over-powering. my advice,get mono-block to run sub

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!!

Take a look at this site this amp is what your looking for for any sub you want a mono block it combines internally both the left and right channel into one.

Could be a number of things: Low power to amp, bad ground connection, faulty amp, or even speaker being overloaded or wired wrong. Check your connections and the wattage of the amp and speakers.

You might not want to do that. The 760W Pioneer amp might require larger wire due to the power consumption of the amp. Most amplifiers require a direct wire from the battery to the amp. The power wire for the factory amp might not require very large wire and if you tie into the power for that amp the fuse could blow and wiring in your car could melt or catch fire, The best installation is to run the recommended guage wire from the battery directly to the amp with a properly rated in-line fuse.

Hello again debrahood196,

Your KAC-5204 amp is only rated to put out 60 watts per channel and really cannot push very hard. If your subs are the KFC-W110S, they are 8ohm subs and you will get better power from the amp by using the bridged connections, positive (+) on the left channel and negative (-) on the right channel. Wire both positives and both negatives from both subs to the bridged connections and the output will be 150 watts into 4ohms. Giving each sub 75 watts should make them push a little harder.

Hi firstof all your deck isnt really putting out 52 watts x4 more like 17-22w rmsx4 ,companies like to throw out some crazy numbers it seems. If your into Kenwood try out a KAC-8404 4-channel on the mids/highs that will put 50 w x4 rms at 4 ohms or if you wanna go a lil louder try the kenwood x600f that will throw 100w rms on each 6x9 at 4 ohms no problem. My system is very similar to yours but running 4 pioneer 5x7's in all the doors and powering it with the 8404 its loud and clean ,fan cooled and no problems at all. My subs are a pair of 15's soundstream t-4's powered by an Alphasonik pma2500a its throwing 800w rms on each sub running in stereo at 2 ohms.It can drown out the mids if i set it that way but my mids /highs cant take as much power as your kenwoods can or else id step up to the x600f too.

No, the sub is dual 4ohms...meaning if you parallel the positive speaker terminals and the negative speaker terminals you will have a 2ohm sub. Conversely, if you series the pos and neg you will have an 8ohm sub. if you wirte to just one set of terminals on the sub you will have a 4ohm sub.

You need to know the speaker travel distance (excursion) and a few other numbers from the maker of your speaker, then you can plug those numbers into a box calculator. Just the wattage isn't enough to know.

Also, you will get different numbers for sealed, ported, and bandpass boxes, so you need to know which type you want ahead of time.

If it was mine i'd want $200-$300 if in mint condition. Try a classified in the local paper or online ads.
