[QUOTE="gunz4me2, post: 6647727, member: 613729"] I just did a little playing around with the Alpine Type R sub in BassBox Pro. IF your enclosure was built to the JL Audio specification of 1.75 cubic feet per sub with the port tuned to 26 Hz, you would be golden for dropping in a pair of Type R subs. I would recommending purchasing the 2 ohm dual voice coil version of the Type R subs. Wire each individual sub in series for a 4 ohm nominal load, then parallel the pair to come back down to a 2 ohm nominal load. As for the subsonic filter, since system was professionally installed, they should have already set that for you. In fact, they should have set your gains conservatively so that you wouldn't end up roasting your subwoofers in the first place. [/QUOTE]
