Hi New the forum but a longtime browser. I recently added a sub/amp combo to my setup. Im looking for some ideas as im not too happy with the performance. I have an old sony ga7es reciever. I had a JL12w6V1 from a few years back when it was in my car. I bought this plate amp from parts express.
http://www.parts-express.com/pe/showdetl.cfm?Partnumber=300-750
I built a sealed box out of 3/4 mfd about 1.3cubic feet which is what JL recommends.
I had to wire the sub to 12 ohms because it was either that or 3 ohms and i was concerned the amp couldnt handle 3. So im now giving the sub 75watts i believe. The performance is really not what i expected. the room is 15Lx15wx8h but its not sealed at all, it flows into other rooms. I got very poor results using the sub out on the reciever to the lfe input on the amp which bypasses the amps crossover. Apparently the sub out is not crossed over as i heard voices from the sub. I have the sub out to the regualr input on the amp. I have use of the amps crossover but the output is lacking even with the gain pretty high.
I have another 12w6 so i considered building another box for the two of them so i could run them at 6ohms netting 225 watts total output to the 2 subs 112.5 each or maybe returning the amp and looking for a used crown or somehting on craigslist. Just looking for some ideas
Thanks
