the trailer is a matter of money. will get one sometime next year, finances allowing. the car is a saloon, i could fit 4 4cubic foot subs in the back - carefully, with seats folded down. maybe i should get the eminence kappa 15 lfa, seems right for a compact sub. won't have the power hadling i hoped for, seems very suitable though. i can't see any reason i should get the cast frame version, maybe i should as the price is very close. thanks for your responses, oyou've cetainly given me food for thought!
