Okay heres the equipment:
Hifonics BXi1608D Amp
2 Alpine Type R 12" SWR-1242D 4 ohms
Soundstorm CAP350B Capacitor
The box was a challenge, this equipment is all going in a single cab dodge. The box is divided in the middle, seperating it into two different chambers,one for each sub. I originally ported it to Alpine specs with a square port, low and behold when the subs come they wouldnt fit. was hitting port. As bad as I hated to I scrapped the square ports and went with a round pvc port. This is the first time I have used round ports btw.
Using a calculator off of the12volt.com I come up with a port length of 8.9in, dia. is 3.5 in. This has it tuned to a freq of 33hz (As recommended by Alpine). The air space for the subs is about 1.7ft^3 a piece, Alpine recommended .80-1.75ft^3 for a vented box.
I wired the subs to 1 ohm, since the amp is "1ohm stable".
Run of 0 guage from batt. to cap, then from cap to amp.
I grounded on a seat bolt.
Checked rca's. They're hooked up proper on hu and into input on amp.
Now for the problems:
First problem, I had no sound output whatsoever from the subs, volume, gain adjustment did not correct this, cap would not turn on, amp was on.
I noticed that the cap has a remote turn-on lead. Run remote from hu to cap then from cap to amp, is this correct? Capacitor started working, still no sound though.
I'm setting there bumfuzzled all the sudden I get a bump, subs start working, very low output though! Volume is on 30 on hu, still low output on subs, I turn gain to 3/4. Subs are working but sound terrible, still very low output for volume to be on thirty. After adjusting on the amp and hu for a while I get a little more out of them, still no wheres close to what it should be, it was getting late so I stopped on it.
What is the problem? Do I have a bad ground? Should I re-wire the subs to 2-ohms each instead of having them both wired together to 1-ohm. Is the amp bad? Is the box my problem? Can someone give me some suggestions, something to try?
