BTB is in this area but thinking price isn't high enough. Seen some 73-78 FJ40 bucket seats they had on eBay that I've bought many nice complete FJ40s for less. $6,000 for some seats that have dents in the back panels is redicuious. Personally was thinking it would work better to put a ramp on one end and test the flex on a monster truck. While never enforced it's actually illegal to have volume over a certain level. While my hearing is not that good anymore I'm very sensitive to bass. Nothing like being stuck in traffic and have the door panels rattling because someone decided that they needed to share their music with everybody within a hundred yards. I like loud music as much as anyone. But only turn it up in the insulated detached garage at our second home. Only vehicle doors rattling are those the parked in the garage. My garage audio is only 130 watts per channel and rarely get the volume up half way in a 1,100 square foot area. Why would anyone need 600 watts to listen to music inside a vehicle?
