Three 8 inch subs vs. One Q12 vs. Q15

[hypnotiq 0]

Hey guys,

I have a dilemna. I have the room to fit any size sub, but i don't really know the pro and cons of each size. The amp is either going to be 1500d or a alpine 1000 watt. The 8 inch subs will either be rl-i 8's or RE 8's.

The enclosure is going to be an infinite baffle downfiring kinda like this:

Thanks.

that's not an infinite baffle, unless he has the sub firing outside the vehicle. no, that's just a simple enclosure with the sub inverted. a sub doesn't care which way it's mounted, it's got cone on both sides, lol.

the three 8s, unless getting a regulated power supply, won't match up for impedance with any amp. however, they will have the cool factor. and the rl-i8 has some serious output potential and power handling in the right enclosures.

what's the overall design goals? what are the design goals for output? low end? and what's the budget?

wheeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee

My goal for designing the box primarily is to bring out the full potential of the sub, but in doing so i also want it to have a show car quality look. I made a thread earlier about an actualy IB (sorry that i mistook the picture i mentioned earlier to be similar), but i soon realized i don't have the trunk room to properly enclose the subs. The above picture is one of the alternatives i was able to find.

The output goal is just to simply LSQ. I don't want to be much distortion at any of the frequencies at cost of spl. My belief is that all of the subs that i'm looking should be load enough for me. I apologize for not having a more specific goal, but i don't really know whats out there as this is my first sound system.

My budget is around 500 for the sub(s).

Thanks.

The 3 RL-i 8's would be very cool IMO, or maybe a pair of Q 10's (since you mentioned Q's) if you want to do a multi sub install.

Is there a pro's and cons of either setup? For example 8's vs. one 12 vs. one 15?

Thanks

The volume of the air displaced is about it...it's not like 8's are "faster" than 15's, or any myths like that...

This is the setup i would be using if I were to get three 8" subs.

The oval is my spare wheel well:

What do you guys think?
