Rear fill

[scatterbrain 10+ year member]

Hi,

My current set up is Infinity Kappa 6.5 inch comps in the fronts powered off a 100 watt rms per channel amp. There's a pioneer champion pro sub in the back running off 1000 watt RMS amp. I want to upgrade the fronts to Morel Maximo 6 and run 6x9 (mid bass only) off the HU for rear fill.

HU us a pioneer dvd player

I have a few options.

1. Run 6x9 (as rears) off HU with rears set to play as subs and set the HPF on the HU at 80HZ.

Will the sub (running of the RCA sub out) function as normal?

2. Run 6x9 (as rears) off HU with rears set to play as full range and use the crossover from the kappas to filter out high frequencies and set the HPF on the HU at 80hz and let the subs hadle everything lower.

3. Install something like Tang Band W69-1042 and run them as sub or full range and set the HPF on the HU at 80hz and let the subs hadle everything lower. Are the Tang band for free air use? Can the handle mid bass well?

Which option is best?

I don't use rear fill so i won't answer the first two but the Tang Band W69-1042 is an 8 ohm driver with a frequency range of 35Hz to 350Hz, you would have to run 2 of them in parallel to provide a 4 ohm load impedance. I don't classify midbass, only midrange. Tweeters, Midrange, Subs.. 20Hz - 150hz, 150Hz - 3kHz, 3kHz - 20kHz..

I never use rear fill

but if you have to do not use 6 x 9

Let me guess, you think he should use a round speaker instead of an oval speaker? For midbass only the 6x9 is the winner. A smaller round speaker has to have a longer 1-way stroke to approach the amount of air a decent 6x9 woofer can move.

For the OP, I don't like any of the listed options. On a low budget, and IF the head unit can run the rear speakers as subwoofers, option 1 is the best out of poor choices. A better setup would be to use 6x9 woofers with both a high pass filter and a low pass filter, powered by an amplifier . This is called a bandpass crossover. It takes the deep bass away as well as high frequencies. You want the subwoofer to do the heavy work making the bass loud, yet you don't want too much music coming from the rear to pull your attention away from the front of the vehicle. For obvious reasons, a more powerful amplifier sounds better than head unit power.
