Trying to decide here for myself.

Which one could be louder? :

8 8" RE Audio subs with 125 watts to each sub in a common chambered sealed enclosure

or

1 18" RE Audio sub with 1500 watts in a vented enclosure



????????????????????????????????????????????????????????????

it would depend on the box, the car, the amps and speakers. but uhm my guess is you could do more with 8 8"s

Box after displacement 2.66 cu ft internal on the 8's
Box after displacement 5.44 cu ft internal on the 18

Speakers:

RE Audio SX18 dual 2ohm (1) rated at 1200 rms

Amp:
RE Audio DTS1500.1 if I run the 8's
RE Audio XTX3000.1 if I run the 18

car:

Mostly price. I can get one SX18 for about the same price as 8 re8's. Everything else i have looked at would either not handle the power or would require way too much power. Plus i have a very small car and want to keep the enclosure no bigger than 38w x 20h x 18.5d

8 RE Audio 8's are $316 shipped and I can use the amp I already own RE Audio DTS1500.1
1 RE Audio SX18 is $273 shipped have to buy RE Audio XTX3000.1 for $230 shipped so $503
2 Sundown SA12 is $390 shipped have to buy RE Audio XTX3000.1 for $230 shipped so $620

Multiple motors means less power compression (heat induced resistance increase)

Remember that your sub is also a space heater. Single motor on 1500 watts or 8 motors sharing that 1500 watts...

NOW, as I am going to lunch, determine what has more SD the eight 8" subs or single 18.

That alone will help determine output no other factors determined.
