[QUOTE="alexbridenbaker, post: 3173362, member: 578750"] Installing 2 amps, new door speakers and 2 subs. First thing I'll do is give a list of what I'm working with any any info/help would be appreciated. Here's what I'm working with: 1. JVC KD-G720 head unit, not much but wanted a front usb port for flash drives 2. Polk Audio DB6501 6.5" for the door 100w rms 3. Average 6x9's for the rear, figured the back speakers wouldn't be heard much over the sub and door speakers qn 4. Rockford Fosgate P4004 4 Channel amp for door and rear deck speakers. 5. MTX Thunder6500D Mono-Block Class D for subs 6. 2 10" jbl gt4-10 subs that I'll pick up friday 7. Rockford Fosgate dual amp wiring kit I've been doing some reading trying to make sure I understand how to set it all up, This was my plan. Was going to use the 4 channel RF amp that though says it's 50x4 rms on the amp, the specs say its closer to 85x4 rms which seem plenty to power the 100rms polk db's I purchased for the doors. My queston is about the subs I was about to buy new off a guy friday, the jbl gt4-10's say they are dual voice coil subs online even though he had them posted as single voice coil subs. If they are dual voice coil, can the amp that I purchased to run 2 SVC subs, the MTX Thunder6500D Mono-Block Class D, handle it? The MTX is rated : 2 Ohm Load 500 w x 1 Low Level 4 Ohm Load 250 w x 1 Hi Level w/ Smart Crossover(s) Power 14.4 VDC Low Pass 40Hz-200Hz - 2 Ohm Load 775 w x 1 Variable 4 Ohm Load 450 w x 1 I understand how to wire two 4 ohm subs in parallel to get 2ohms which my amp would have been fine to push but if the subs are in fact dual voice coil, do I need two amps to push them or is there a way to make the mtx do it without causing any problems? A guy yesterday told me I would need either a different amp that was not mono channel or a second amp to run both of those subs. Thanks so much up front, any help appreciated. [/QUOTE]
