Wiring problem for my Kicker ZX450.2 amp

Well you really can't run both speakers on one term. because you will over heat the amp , unless your amp is rated at twice the capability of your subs , Then if so , Try positive to one sub , then neg. to the other sub , then bridge the remaining positive to the remaining negative terminal , But it is really best to get a two channel amp for your subs !!!

You are running more then 1 speaker on a 1 channel amp. You need to verify how many ohms your subs are, and what ohm you are wiring your subs to run at. Your amp is only capable of running at 2 ohms.

Here is a link to figure out how to wire them correctly.

Here is a link to your amplifiers specifications.

If you want to use two Kicker Coaxial or Component Speakers on a single
channel of your amplifier wire the speakers in series. This will improve the sound quality, lower the total harmonic distortion and
lessen the thermal load at the amplifier. This may prevent an amplifier from shutting down, due to over-current protection circuitry.....so definetly on the SUB terminals as this channel provides the better bass response........

if you bought that equipment today then your answer is yes your amp will power the subs but if i was you and you want more bass I would go with a two channel amp or even a mono block amp that will be 1 ohm stable and if you decide to do that you might want to get subs that are dual 4 ohm voice coils and run them in series that will get you 1 ohm of resistance

Short in amp ? try swiching wire's to speaker's around . if other speaker then work's , speaker's are both fine . if not , then short in amp , or blown channel in amp . get new one or find someone who know's more than i do about amp's

Run the subs in series then bridge the amp. So run the normal + to - to the one sub then hook up a spare wire (not connected to the amp) to the same + and - connections. Then run the spare wire to the + and - of the other sub. This will tie the 2 together so you can bridge the ampfor more power instead of using 2 seperate channels.

scanman84: i would recommend using the 2 channel 300W amp to drive the dual voice coil alone. i wouldn't combine the single channel amp with the 2 channel. you can't tie the 2 channel outputs together & use that on 1 voice & attach the single channel amp to the other, plus there could be slight differences in amplification & timing which, could cause the sub to have minimal movement or cause a canceling effect which would reduce the spl, sound pressure level. if you need more volume use the lowest impedence speaker recommended by the amp's mfg & if you need serious volume, go with a higher output single 2 channel amp. just make sure you have sufficient wire size to handle high powered amps. example, 8awg wire is rated for 73 amps. also make sure the amp is well grounded with nut & bolt connections to the frame & that there is good ventilation.

peace-out

How you wire it depends on how hard you want drive your amp. If your woofer runs 4ohm per coil I would wile it in series (amp +to sub +1 sub -1to sub +2 amp - to sub -2) then run it for a week and see if it has enough power. the lower your Impedance (the resistance load on the amp) the harder your amp works and more THD (noise) is produced. (Dclass amps aren't know for being clean to begin with) configured like this your amp will see 8ohms and sound the clean east. if this turns out to be not enough power wire it in parallel and double the output. wire amp + to sub +1 and +2 then amp - to sub -1 and -2.

A word to the wise... start with your volume very low and work up slowly most speakers will puk up the voice coil before the amp starts to get warmed up. you would hate to have to buy a new sub.

Have fun

check the wire inside of the sub box

Disconnect all speaker wires and signal cables from the amp. If it powers up, the wiring needs to be checked. If it still shuts down, the amp likely has blown output transistors.
