my thoughts on subs
#1
start rant:
I have dual 10" blaupunkt overdrives mated to a power acoustic 1800w mono block, it provides way more then enough bass, now that I have heard what it does I'm thinking this is overkill and I wish I hadn't gone so big, like the problems I'm having with alternators and adding a second amp for the 6x9's is just not worth it
a single 12" sub with 350w rms then a 150w x2amp for the 6x9's would work just fine for me
right now my trunk lid vibrates like crazy, yeah seal the trunk is an option but thats lots more $$$, and the sub box takes up so much room already
why can't 6x9's put out enough bass? maybe mine can but they have always been capped and underpowered with a 2x75w amp so I have no idea of what they are realy capable off

Wilt,
A couple of recommendations:
1. If you're not happy with so much bass output then simply turn down the gain on the amp or the level control comming out of your deck. This accomplishes less output and less distortion from your subs.
2. If you do lower the gain on your Power Acoustic then it won't suck so much power. Therefore, your alternator will be happier.
3. I'm not familiar with your amp but if your amp features a bass boost then you might consider lowering it. I'm told that for every 3 db's of bass boost added, the amp requires double the power.
4. Look into the crossover frequencies going to your components. They may not be producing bass simply because the signal going to them is cutting off the bass signal.
By lowering gains and manipulating crossovers, a system with a lot of power can reach its greatest sound quality potential.

I put lots of time and effort into making that box, its stronger then your typical commercialy availble box, I know this because the one I got from the store for a single sub didn't use screws every 1 1/2" along each seem, or calking, may have been held together with just glue
also how do you know if a sub is distorting?
I can tell if my front tweeters are distorting but subs have such a low sound its hard to tell I think

Well if the box is built accurately with sq in mind then the bass notes should sound accurate. If not, distortion has likely begun.
1)Set any bass settings to "0". That includes Bass boost on the amp or HU, EQ, turn Loud button off.
2)Turn the gains down.
3)Use an active crossover or try caps that crossover the 6x9's as low as you can without having them go into distortion too soon.
4)Set the crossover for the subs lower in accordance with the 6x9's. (does the 2x75w amp driving them have a crossover?)
You might have the subs trying to produce too much upper bass frequencies which is why they might be sounding boomy, etc.
