Thank you everybody I will probably get another amp dedicated to just the speakers.

Yeah those are my speakers, the GTO8628 but mine are the coaxial version rather than the component set.

The 1200w crunch is a 4-channel amp producing about 500w rms total. The rear channels are bridged at 4 ohms producing about 200-250w rms. The front channels are set up to run 4 speakers, so each speaker should be getting around 55w rms each if wired at 2 ohms. The stock headunit is indeed installed, but I have achieved an RCA output by tapping into the circuitry within one of the control boxes.

Hello all, I am currently in the process of revamping my system. I attempted to do it last summer when i knew nothing about car audio, and it did sound quite decent. I now realize that there is alot more potential. As of now, there are JBL Grand Touring 5x7's up front and in the rear. In the trunk is a Pioneer 12" sub. The powerplant behind the whole deal is a 1200w Crunch amp, which gets the job done quite well. My problem with the system is the bass coming from the speakers. The only way i can get the speakers to sound well at high volumes is setting the HPF to the lowest setting, which on the amp is 60 hz. If i set the crossover to Full, the speakers sound good until about half volume. After that it is complete garbage. The "bottoming out" just kill the sound if you know what i mean. And for any of you who have the thought in their head, I have in fact set my gains properly with my trusty oscilloscope. I know speakers are capable of reproducing crisp and clear mids, because my friend has a 2011 Lancer with the oem RF system. When a song with good mids is played, your legs get a massage I believe he has 6.5 Punch components up front, and 6.5 coaxials in the rear. Its all stock, but Rockford Fosgate made the speakers. Now i can get to my question after describing my situation. My car is a '99 Sable, and it has the abnormal 5x7 speaker size. I plan to get some 5x7/6x8 to 6.5 adapters so i can throw a decent set of components up front. I know nothing about manufacturers and their reputation in terms of sound reproduction. Based on what some of you have experienced, what would your recommendation be for me? I think JBL doesn't have good bass reproduction. Thanks in advance.
