You can build a new enclosure. 5.5 is far to small for that 18. Minimum I have ever used was 6ft3, but in honesty they like even larger then that.
It is hard to base anything audio related off of other's builds.
AQ's love large enclosures. Sorry but no way around that what so ever.
aq's love small boxes not large, they need gigantic ports and small chambers.
Trust someone who worked for AQ and builds boxes as a semi-significant part of his income... or trust someone who's an asshole who honestly believes he knows everything about car audio?aq's t/s are pre broken in, and worth less. I say run an abc box,
2.6ft first chamber, 1.3 second chamber.
45'' of port big chamber tuned to 30hz and second tuned to 42hz
Naw, I posted what needed to be posted. Everyone is allowed to have their own opinions. The OP has been given info and can do what ever he likes with it.Me thinks this is going to turn into a pissing contest
To do so you have two choices to pick from,I like pissing contests, Pro-Rabbit I challenge you!
