The other day my sub quit working and somehow something inside my mtx amp is loose. not the fan but another large important piece. Not that i care cause i hated how it slid around my trunk area but i want to know a good fairly inexpensive component system. I've got a 2 channel 500 watt amp right now. I just want to stick to the rear 6.5's. Its a '99 Integra Coupe. I want a pretty decent amount of bass. Not real concerned how crisp and clear it is. I was thinking Infinity Kappa's. Also i want to keep the pair under 100 if possible.
