SUBWOOFER ENCLSURE FOR TWO PIONEER TSW307F 12" FREE AIR
i m building an enclouser for two tsw-307f subwoofer from pioneer ,it's a free air subwoofer .the box size is 3.1 cubic feet .and i want to install one of the sub inverted(i will invert the polarity in the amp)
i did a graph on win isd and it shows a peak of 100db
so do u think it's a good setup
i like the sub coz it got 94db all the designed subs for enclouser got 89db
can you please advice.clear loud voice is all i need

Do you have the subwoofer amp connected to the pioneer thru pre amp connections; pre amp output of pioneer to pre amp input of Kicker amp. Page 10 of the manual explains how to adjust the subwoofer output. You can select the cutoff freq. that will pass to the subwoofer; The slopes don't match perfectly, but if you use the -12 slope , it should work fine.
80HZ same as kicker cut in freq
It will drive the speakers but not the subwoofer. U need to connect the subwoofer pre- output from your amplifier to another amplifier that will drive the subwoofer.
If you connect the subwoofer directly to your amplifiers speaker output it will force the subwoofer to play the entire spectrum of frequencies (not designed to do that) consequently causing damage to the sub and maybe even the amp. So use the sub pre out.
Hello sir, hi, YOU DON'T bridge no more speakers, this upsets the impedance load of the amp. to install another sub-woofer, get another amplifier. You may have damaged your power amplifier, If you experience repeated fuse blows, your power amplifier is now SHORTED. This needs IC amplifier replacement.
dude TRUST me what you are using and have setup already is plenty..ONE TIP...of all things anyoine ever needs to worry about is the R...M....S power rating...the PEAK means NOTHING! its safe and fine to use what you got.
Run one set of RCA lines from
head unit to amps if you only have one set of pre-outs on the head
unit, then at the amps, use an electronic crossover to split between
the two amps, and this will also allow you to control what frequencies
go to which amps/speakers. You should use one amp for the speakers and the higher power amp for the subwoofer. You should not try to connect both to the subwoofer. Use 4gauge cables if possible. If you have more questions, just ask.
here is a short test you can try, remove the rca audio cable from the amp & connect a diskman or toher audio o/p device that you can hook up with the same rca wires, turn on the amp & see if you have sound. you can also remove the speaker wires from the sub & using multi meter read the ohm's of the sub, most subs are 4 ohm. Hope this help locate your problem
