[QUOTE="Doxquzme, post: 8855257, member: 689267"] It’s always important to remember that when you go to a stereo shop for advice, they will always lean on products that they retail, nothing else. That said, I've used the GM-D8701, 8604 and 9601's, most all of the GM-D series (and PRS) amplifiers extensively and they consistently produce to rated power and stay relatively cool – never blown one yet! This amp and sub should work well together. That is a decent subwoofer and it doesn’t lean towards a sealed (what you have) or ported (the one with the “hole” in them). Here is what the alpine site says. [B]Enclosure Compatibility Sealed Box Volume:[/B] The recommended sealed box volume (gross) range is from 0.65 (18.4 liters) to 1.1 ft³ cubic feet, (31 liters) with 0.85 ft³ cubic feet (24 liters) being the ideal size. If you are on the small side of this, may want to up the size of the box. Additionally, .5 to 1 pound (.25 to .45 Kilo’s) of Acousta-stuf will improve the overall sound of your sealed setup, in my experience, quite a bit. [B]Ported Box Volume:[/B] The recommended ported box volume range is from 1.1(31.15 liters) to 1.6 ft³ (45.3 liters) The ideal size is 1.55 ft³ (43.89 liters) using a slot port measuring 12½" (width) x 1½" (height) x 22" (length), resulting in a tuning frequency of 36 Hz. As was mentioned earlier, I would set the crossover to 80Hz to eliminate possible peaks from popping up above that frequency and stuff the box with Acousta-stuff, you should see a real difference. If you are clipping then you most likely have the gains set incorrectly. Go back to the shop and ask them to help you set the gains and the crossover, that’s the least they should do. 800 watts to that sub should be putting out some serious volume. Are using an LOC to the amp from the head unit for signal? If you are, that could be the source of the problem too. [/QUOTE]
