philrab Posted November 3, 2014 Report Share Posted November 3, 2014 Knowing max dimensions would be fairly helpful, as would knowing what type of music/what tuning frequency you want. Or we could guess...... 2015 Toyota Tacoma Build Thread 2007 Mazda 3; 5000K HID's, Kenwood Excelon KDC-X997, Infinity Reference 6.5 comps in front and coaxials in the rear doors, JL 320.4 four channel, Rab Designs built ported enclosure with an SA12, Kenwood monoblock, Redline Leater shift boot/e-brake boot/center console cover, JBR short shifter/shifter bushings/rear motor mount.

Aj11 Posted November 6, 2014 Report Share Posted November 6, 2014 to small... i had my 12s in 6cubes. the newer gen rs. they dont make The newer gen r 15s. but i wouldn't go smaller then 7cubes net. personally id go 8cubes or more. rs love big boxes tuned low! I've owned every gen and size type r they have made. they are spl subs (with no sq) unless you tune low! considering your only putting 250w over rated to them id try to get as close to 4cubes net each and stay below 33hz. just saying if it was my build id do 8 cubes at 28hz with around 112sqin of port. just make sure your gain is set right jvc deck stinger 1800 front hc 2000 kinetic rear 2 runs of 1/0g big 3/4 ct 60.4 2 ct 1400.1 ct EXO 15 d1 lots of deadner type r comps front stage 6 kicker tweets rear stage lots of great stuff coming soon ho alt more bats ct comps for front stage more deadner sweet amp rack lots of L.E.D lights new deck (thinking 80 prs, or flip out) Link to comment Share on other sites More sharing options...
