Another This Vs That

[Boon]

You need more amp for a start. If you're even seeing 2000wrms after rise I would be amazed.

4 SDC15's should kill 2 18's.

that massive amp your using sucks i know ive had that exact one and though i was doing something those 18s want way more power than it can dream of putting out change that first

I had a T20001bd and couldnt have been happier with the Massive, even though im a huge Rockford fan.... Is it really worth me spending the money on an AQ3500 or SAZ?

I agree i may not be seeing the full 3kwrms, but look at it this way

Couple hundred watts more or....

30% more cone area

I remember when i had 2 12" T1's off a T10001bd and went to 4 12" CVR's(back in the day) and was simply amazed at the difference.

Im wondering if this would be a similar change.

The AQ is rated 1kwrms.... i dont get how your saying it can take way more than wat im giving it. Yeah ive heard of people running 2 and 3kwrms but thats not practical, and im not steve meade so im not good with clipping,gain settings, etc. I figure if im giving them 1500 a piece thats more than enough, i dont really want to flirt with thermal or mechanical issues.

If i knew how to design a box to run more power and have my settings to where i wouldnt have to worry about cooking my subs i would definately throw way more power at them, but i dont want to run over 3 or 4kw in my truck.

But i do know what your saying, im not trying to contradict anyone, if anything its good to know this stuff.

Well both will make a huge improvement...you just have to decide which you wanna do first. Boon is just saying that a bigger amp is definitely needed.

[mxman38]

yeah im not disagree with that but then that leaves me with 1 more question.

If i order the 4 SDCs they are only 600wrms per woofer... Assuming thats 2400 watts and im getting around that after IMP rise, how much more should i push to these woofers safely?

i cant just buy a bigger amp for my HDC3's because i will be at 2 ohms on a SAZ or AQ amp.... thats or .5 ohms, which i dont have the electrical for.

[mxman38]

ok so i was doing a design on sketchup and ran into a problem, if i do the 15's i will have to put the port on the side in which case i will need a 5.5" opening to achieve 31.9HZ

I then will only have 10 cubes and 130 inches of port area... FML, this was an epic fail

10 cubes and 130 inches is nice port:box ratio-wise but not enough airspace for the subs... especially with the power.

Believe me, you're not getting 2400w after rise. You might be getting a touch more (like 2500 total) before rise but that's about it from those amps. It's pretty damn similar to a AP30001 inside and despite all the poorly done bench tests on the net they only do about 2500w @ 2 ohms before THD goes way up.

[mxman38]

What am i going to need for this to work space wise?

[mxman38]

o shit, i just noticed that i typed 26 tall instead of 36, lol. I actually will have 14.7 cubes with 189 Sq inches of port area.

[mxman38]

Bump, is this enough airspace, without driver displacement?

Il pay someone via paypal if i have to for a box design, just need some help.
