Hi... I'm looking to power a set of 6.5 front components and a single 12" sub. Is it better to get a d class mono amp to run the sub and a separate 2 channel amp for the front or just get one 4 channel amp and bridge the rear channels for the sub.

Thanks for your replies. [img]smile.gif[/img]

If it was me I'd go with the two separate amps so u can get full power to each component outta each amp. If u go with the 4 channel ur splittin the power everywhere and an un even amount if im correct? The sub more than likely can handle more than the components so possibly risking over powering them as well? I could be wrong im just givin my two cents.

Depends on the amp, and what type of x-overs you are gonna use (passive or electronic)Both set ups will work, although you can have more control with two amps.

Hi ... Thanks for your reply. I'm thinking about getting an Alpine 9815. Same as hog_hauler. I should be able to use the internal crossovers within this deck right? Do you find the blue buttons too bright at night or not? I'll be running a set of 6.5 Polk Momo 80w rms 300w peak and an Eclipse 12" single 4 ohm 300w rms 500w peak. How much power should I be looking at running to these speakers to make them sound their best? Now that you have more information, would you suggest a 2 channel and a mono block or a 4 channel to run all.

Give the Polk's their full 80 watts RMS. Assuming they are a 4 OHM configuration, consider a 2 Channel amp such as the Phoenix Gold Tantrum 300.2. They're dirt cheap on sounddomain.com right now, although sounddomain only ships Phoenix Gold to the USA.

For the Eclipse give it the full 300 RMS watts if not a little bit more. You could even run two of the Phoenix Gold 300.2. One to the speakers and one to the sub and it would make for a nice consistent setup.

The only reason to use a 4 channel amp is if you plan on upgrading in the future. A 4 channel amp will give you a great deal of diversity in a future setup especially if you choose to throw another sub or a more powerful sub into your system. This way you can buy a bigger mono amp for the sub(s) and still designate the 4 channel to the speakers or throw another set of speakers in the car and still power them with the 4 channel.

muskyhunter, I have a friend running a pair of those eclipse subs in a sealed box on a mtx 1501d. As long as you careful with your power those subs will last a long long time. Plus they sound pretty good too. Muckalucks right, try to feed everything you've got their rms rating in power. The sub will easily handle 300 rms but you also dont want to drive the guts out of it either. I don't think i would get any bigger than a 500 rms amp for the sub. Then all you have to do is set the gains properly and your good.

If you do go with the 9815, then defintely go with two amps to take advantage of the head units built in x-over. I don't have any issues with the blue lights, however I can't remember the last time I drove at night. As far as power goes, I personally would use a amp for the front of at least 100 watts rms and for the sub,I would start at 300 watts rms.
