Default KL40 amp problems

First time responding on here but I've been having an issue with high swrs on my kl 60 which I believe to be very similar to the kl 40. I have tested the swr in multiple ways in the system, with amp and without. To give a rundown of my setup I have 9ft of coax running from radio to amp because the radio is mounted on the ceiling console however you want to call it. I have the amp on the floor then I have the coax running out to the antenna which for that antenna I'm wanting to say 17ft but I'm not sure what the antenna came with. The antenna is a tram 300. So without the amp being there and putting a meter there instead to check swrs, and with a meter at the back of the radio everything seems within reason swr wise. I'm getting between a 1.4 to 1.6 on 1 and 40 which I'm not complaining though when it rains it starts to climb on 40. My main issue is when taking a reading with the amp there but not on, taking it from the radio side or antenna side it reads a 2 to 1 on 40. I suspect that the amp is the problem because everything checks out without it. Now get this, with the amp on, on the antenna side it drops back down to 1.6. So it's only high with amp being there and off unless I max radio power to amp when on then itll show 2 to 1 again. Anything below 3 or 4 watts deadkey its fine. So someone explain to me what inside an amp would give for a high swr when off, thanks.
