So I was able to fit some 9 inch woofers in the front, they definitely make the sound much fuller especially around the mid bass region of 80-250hz. To me it sounds like mini subs but of course it’s no replacement for a sub system imo anyway out with the 6.5s and in with the 9s. also, upgraded the amp to a 160watt per channel class AB from zapco. Previously had a 70watt per channel from morel and it sounded fine but really lacked depth at higher volumes. This new zapco brought out much more bass and overall a cleaner amp than the morel mps.400. So imo always buy the highest amp you can to have that head room for loud dynamic bass.
