[QUOTE="AndyGiff, post: 8697196, member: 676893"] Hi guys, just finally finished installing my system and I am having an issue with my subwoofer. Here are my setup details. Electrical- Mechman ho alt ( 280 ), xs power D5100 all zero gauge power grounds head unit is Pioneer AVH-P2400BT -using fronts as input to dsp (input 1 and 2), as well as the subs out into dsp (input 3 and 4 ) ( getting some noise from HU as well, its clear while streaming though, still working on this issue as well lol ) dayton 408 dsp w bt dongle 2x pioneer amps bridged at 2x300watt each for mid and mid bass (prv 6.5 neos and anarchy 704s) 1 alpine ab amp for my tweets 2x150watt (massive audio CT2 II tweets) 1 skar rp 2000.1d for my skar 10" evl dvc 2 ohm sub wired to one ohm ( using far left positive and far right negative speaker terminal on amp for sub woofer speaker line) So far everything minus the sub is working great! Sub has some sound coming out of it but it is playing like its a 20 watt amp, started with gain at a quarter which should have had the sub thumping hard, I can barely get any bass out of it even with volume at max, dsp maxed, gain way up at like 60%, ive double checked all my freq on the channels as well as running the amp seperate from the dsp to see what was going on, same volume with or without the dsp, I am thinking I maybe got a dud amp or something? Could anyone give me a few ideas to check that would tell me if its a dud or not or if I am being an idiot? I was very careful with all my wiring, used the best stuff, double checked all my connections, tried a separate sub as well with the amp and got same results ( was at 2 ohms instead of 1 ohm but still should have been shaking the whole damn garage ) Any help or input would be greatly appreciated! I am stuck and just not sure on what to do at the moment, seems like everything else is golden except for the sub / amp problem. Power wise the skar amp is run right off of the zero gauge from the battery, I split it using a block to go to the other amps and have zero gauge going into the amp itself, double checked the ground, seemed fine, using a ground block with zero gauge attaching to bare metal on chasis in trunk. Power light on the amp is on and the protect light has not come on at all, subsonic, low pass etc are where they should be. Any help would be great guys, taken me forever to get to this point, any other trouble shooting I can do to figure it out let me know, I am still a bit of a amateur. Thanks in advance guys and gals!
