Ok, here's the setup. I have a Solo-Baric L7 12 in a small sealed box with a Sony 300W 1-Channel D-Class Mono Amplifier (at 4 Ohms). I have it running at 2 Ohms, therefore, it is pushing 600 watts. The amp says it is stable down to one ohm which would give me 1000 watts, but as I have read there are very few amps that can actually run at 1 ohm and not fry. Being a broke 16 year old, I have no intentions on even trying this setup at 1 ohm, even though I believe the solo-baric would take the extra 250 watts over it's rated 750W max. I have read reviews on these subs that commend them on their small box requirements but the box I built is a little on the small side, so I do plan on buying a box of the correct size in the near future, but I don't think that will solve my problem. Oh yes, my problem. For a Solo-Baric, I think it distorts way too easily. Yes, when I put a bass excursion test or something like that in, it will render my rear view mirrors useless...but when I listen to regular music, it does not get quite that loud. Anyways, if I have confused you with all of this jibberish, I'm sorry.
But it all narrows down to this: What do I need to do to get my Solo-Baric sounding as loud as it should?
