Like mentioned before, go upgrade the electrical system. Go ahead and get the ho alt. Then go from there.

I know that low voltage can do damage, but does it cause a clipped signal? Is that why they get hot after about a minute and a half at full volume?

very possible

11 volts ftl... look into a new batt if urs is old and def big wire... bout $200 will have you set

They get low, but they dont get extremely loud doing it. Higher notes to me is something in the 40's. I know I need a HO alternator, but is it going to make such a significant improvement that I'm never gonna want a diffrent sub again?

if i were u and i was just really lookin for some new subs, i would go with 2 15 H2's, those motha ****as pound hella hard. I got 2 15" L7's (2006 Model) not hooked up yet, but i can tell u right now, those ****s are loud as hell, ive seen and heard them in action, maybe upgrade ur electrical system and pick up some 06's L7's?

he doesn't want 06's if he's already upset with the output of the 04's

the 06's supposedly CAN get louder, but they take a lot more power to get as loud as the old models

yea what is "low end" to you?

mine got down good to about 35 hz, and then below that they tended to rolloff , but i was also underpowering them + had them in a crappy small *** box ...

Is your box braced properly? 9.5 CuFt is a pretty large box, and you will notice a decrease in output if your box is floping around like a fish.

Yea, It has a subsonic filter. I'm pretty sure I have it set on 25hz. It may very well be the box. When I built it, I didnt use bracing at all. You wouldn't think that it would make such a huge difference with or without bracing. The bax practically takes up the whole back end. They are pointed rearward.

Pointing them forward didn't make a difference. It was actually not as loud. It doesnt seem like there's enough room back there for the bass to get through to the front. I was curious if a smaller box would better utilize the space back there and give me better output.

i have 2 L7 15's with about 1300rms to each in a 9.5cf box and it is loud as hell, really loud.

but my box is also tuned to about 38-39hz, if you are looking to get loud you have your tuned (33hz) tuned too low.

how much port area do you have, mine is about 80sq inches at 9inches long, the more port area the louder you will get (generally) see if you can get about 100sq inches of port area and tune it 38-40hz and you will be happy as hell, and makes sure you throw atleast 1300rms to the subs as it takes some power to make a port that big work good for you.
