Do you think its worth the money to buy an amp for two 6x9s or is running them off the HU going to yield the same results (just quieter). To make this happen I would have to buy another amp, distribution block, increase the current amp power wire guage and maybe add crossover. So is it worth $200 for this upgrade? Could you suggest a good, moderate priced 2 channel amp with 60-75w rms per channel with rca outs. Thanks.
