Affects of vehicles on SPL
Ok, I've got a question or two. A friend of mine has two kicker comp VR 15's pushed by a Power Acoustik Gothic Series 1600 watt amp. This amp is rated at 740 watts RMS/ 1600 peak. He has these in a ford bronco. Its bigger than a ford explorer as far as internal airspace goes. I have two solo baric L7 12's pushed by a JBL 1200.1 in my single cab F150. Sound wise to our ears anyways, his seems much louder and it also is more noticeable on the body(actually feeling the bass). I always thought that the VR 15's and the L7 12's should be similiar or that the L7 12's would probably beat the VR15's when on about the same power. Both sets of subs were in sealed boxes, about the middle range of the recommended, and I actually had more RMS power going to my 12s. He has not yet metered his 15's but I think his is louder. What are the affects of the vehicle on this? Would my two L7's in his vehicle seem louder than the 15's? Would his 15's in my truck(if the box would fit) seem about like the L7's or maybe less? Let me know. Also shouldn't it be easier to get Sound pressure in a smaller area than a huge one? Thanks.
