Sorry! Sorry!! Sorry!!! I apologize profusely for being away so long, i hope you guys have not tuned out for good. I got caught up in another thread and neglected my own.
Anyway... I appreciate the feedback and I hope I can clear up a few things, as I said I hope you all are still tracking this thread, as I still have not figured this out.
I am very sure my amp is one ohm stable. It is a Hifonics HFi3000D. The issue I have , the reason I can not just parallel the two L7's together, is the enclosure is sealed and each sub has it's own sealed compartment. I would either have to drill through the dividing wall or snake a bunch of speaker wire back and forth on the outside of the box. Neither one of those options will work for me. Now, I understand that both sets of speaker inputs on the amp are connected internally, so wouldnt that prevent the amp from "seeing two two ohm loads?" I am asking, so do not mistake the "quotation marks" as me being a smart ass. That's kinda what it looked like to me. Also, to answer the other unanswered question from above (I wish I could figure out how to upload a diagram to this forum. If anyone does, please enlighten. You can email me private so as not to anger the forum Gods by straying so far off topic. chrisv213@gmail), I have two pairs of speaker wire (one each + & - from each sub) running to the amp. Each attatched to it's own terminal, but since they join together internally, that doesn't really matter. Reversing direction now to let you know the rest of the wire path. The sub enclosure has two terminal caps, each with one positive and one negative post dedicated to each individual subwoofer. So on the inside of the sub box, each subwoofer (isolated in it's own chamber) has a positive wire from the positive terminal of each voice coil, twisted together and secured to the positive post of it's respective terminal plate. (I use heavy duty gold plated binding posts that accept banana plugs. I just got used to them in all of my home audio systems) Then, as stated above, two runs of speaker wire, one from each sub, to the amp. Each wire has a dedicated positive and negative terminal, but they are connected inside the amp.
Alrighty then, Department of Redundancy Department. Hopefully I have covered everything at least twice. If any of the past posters are still out there, suggestions are greatly appreciated. BTW-the system sounds ok. Pioneer AVH-4300BT head unit, Hifonics HFi 55 four channel (110 x 4 rms @ 2 ohm) pushing Hifonics Zues 6.5" components in all four doors. I have a pair of additional tweeters in the front center console and a pair of Rockford Fosgate 6x9 coaxils in the rear deck lid. That makes eight speakers on the four channels. Each quadrant of the car has two speakers that are wired together so the amp sees two ohms. I also have a Soundstream processor that cleans up bass and boosts voltage to the sub amp, up to 10 v. My battery is in my trunk so I do not have any long power runs (I use 0g and 2g power/ground cable any way) and I also have a Kinetic 800 power cell right next to the battery. The digital readout on my main fuse holder reads 14.4 - 14.8 when the car is running, and only drops to 12.9 - 13.5 when engine is turned off. I have a 150 amp alternator. My reason for dumping out all the minute details of my system is that while it sounds ok, its not where I think it should be, both in terms of overall spl (a victim of my alternator, I am guessing) and sq (who knows, soundwave interference between the speakers maybe. I could possibly have too many. ;))
OK, I am done for now. Thank you in advance for all of your wonderfully helpful and detailed responses.
