Has anyone done this before? I was wondering if I would run into any depth issues or any issue in creating a baffle to fit the factory location which is 6x8s.

I need a box for two Fi Q 12" ported in the trunk of a 2007 Mazda 6. I went out and took some immediate measurements of the cargo space in the trunk. Roughly 28" D x 18" H x 45" W. Looking at roughly 2.0-2.5ft^3 per subwoofer, with the box's ports tuned to 30hz.

The box looks really great, and are those wires coming from the terminals on the inside? If so, are they soldered or simply connected, and eventhough, that is really nice and saving me the trouble of clamping on wires to the inside of those terminals. Once again, looks really nice.

Looking good man, can't wait to get that thing in my truck and produce some sound.

Thanks for the multitude of replies!

Email sent, tell me if you got it.

I have the design, the dimensions and everything. I just need it built and shipped. Need to know pricing info and other details if possible. Thanks.

Just making sure, I've ordered another one.

My 12" Fi Q came in today and I noticed that the magnet slugs on the motor weren't lined up just perfect. Here is a pic.

I decided to change the "sub-stage" in my truck from that single 15" in that ported enclosure that just never seemed to sound right to two Fi Q 12" in a dual chambered sealed enclosure. The enclosure has about 1.5ft^3 per chamber. The two subwoofers are without the BP option and are being powered by an AQ2200d amplifier.(2200watts@1-Ohms). Hopefully sending each Q with around 1100watts. The subwoofers are DVC 1-Ohm, wired in series to 2-Ohms per subwoofer and bringing a 1-Ohm load on the amplifier. The first Fi Q 12" has been bought and so has the AQ2200d. I plan to order the second Fi Q in a week. What influenced my decision for this subwoofer stage: 1. The Q's performance in sealed enclosures. 2. The two subwoofer distributed inside the cab should even out the amount of bass experienced on both the passenger and the driver side. 3. The smaller sealed box should provide more leg room then the previous huge ported box. 4. The Q's ability to get real loud and sound real good, also their notorious low end. 5. The AQ2200D does rated power, good backing on this amplifier. 6. The AQ2200D is used, but only 10hrs of run time, the seller is selling it due to downgrading his setup to put the backseats back into his ride and guarantees its functionality. I've been sorta deemed as an extremely unlucky person in car audio but I'm hoping things will shape up with this setup. My previous setup was a 15" Fi Q Dvc 2, in a 3.35ft^3 box tuned to 34hz. There may have been a design issue with the port in relation to the box and subwoofer which may have caused problems. It was also powered by a Hifonics Bxi1606d.

Well, I emailed Rainbow Audio after I replaced the halogen bulb protection feature and still the tweeters were attenuating and they informed me the following: "Our Sound Line crossovers feature two tweeter protections which are connected in series. By replacing the halogen bulb with a silver wire jumper you by-passed just one tweeter protection. The second tweeter protection is a PTC which is kind of resettable fuse. The PTC protection is calculated according to the maximum power handling of the tweeter. Whenever the PTC will shut down the tweeter, you have driven the tweeter to the outer limits! We do not offer to by-pass the PTC as this is the last boarder before the tweeter dies by over-powering. You may short-cut the PTC by soldering a jumper on the copper side of the crossover PCB. The PTC is that yellow/brown round small thing with two wire connections. Please kindly note that by by-passing the PTC warranty claims for burned tweeters can not be accepted." But I could see if the tweeters are sounding like they're being stressed and losing clarity or distorting but thats not the case at all. They are loud, loud enough that loud snare drum strikes can cause you to blink your eyes. But its very clear.

Lol in the last month 2 of my dogs got hit by a car and killed,both of my vehicles broke down,and i lost my job 2 days ago. Ive overpowered my Infinity perfects with 300 rms on each side and nothing happens like this. That really sucks...

Heh, I really do, its true. Alot of people have told me that I'm a great installer as far as wiring, setting up, planning and designing but it just seems that with everything I get, nothing seems to work completely right. I wish there was a way I could get my hands on a another duplicate set of crossovers for this set of maybe a decent passive crossover so I can see if its actually an issue with these specific crossovers or an issue with how much power I am sending them...... Ya i was thinking it might be a problem with a crossover,but do both sides stop playing at once? Nope, one side will quit......then the other side will quit. Eventually both sides will both quit.... But they don't both quit at the same time.
