jw if anyone has any suggestions on how I can get louder

i drive a 04 type r ive dynamated the entire car I use 2 audysy batterys all single ott streetwires wiring , soundstream 4000 d amp and 2 soundstream t5 12s , im currently hitting 148 on the termlab , I have a custom box being built but jw if theres much else I can do ?

try more and more boxes with different sizes and tuning. or a bigger amp

im getting a box built right now , I might go with the 10000d amp

the draw from the 10,000 would be insane... The 6500 would prob be better for you.
Test TEST TEST... trying several boxes, as generally the first box built isn't neccasarily the best

ya either stay with the 4000d or go with the 6500d i dont think buying another amp is the answer as much as tuning and finding the right box

you should always try get the most outta the gear you have, and once you do if your not satisfied...THEN look into new gear.
Are u tuning for daily driver or spl??z??

tunning for spl competitor im also sponsord by soundstream

you should post up some pics of your box and it in the car! help for suggestions
