i got 2 10" Kicker CompVR 05CVR104

Details:

 

» 10" sub with dual 4-ohm voice coils

» suitable for marine use

» injection-molded polymineral cone

» double-stitched, foam-ribbed Santoprene rubber surround

» frequency response: 25-500 Hz

» power handling: 50-300 watts RMS

» peak power: 600 watts

» sensitivity: 85.5 dB

» top-mount depth: 5-9/16"

» sealed box volume: 0.8-3.0 cu. ft.

» ported box volume: 1.25-1.75 cu. ft.

 

looking for a amp for these guys. wondering if anyone knew any good ones. im kinda stuck i choosing. should i be looking at a amp that provides 300w RMS x2 @ 4 ohms or like most i have seen 200W RMS x 2 @ 4 ohms. will there be a signifant difference?

Unless you plan to run your subs in stereo, I would go with an amp like 500-600 watts RMS x 1. If you are going to run your subs (and voice coils) in parallel, then you will have to get an amp that is 1-ohm stable. Or you could always run the voice coils for each sub in series, then parallel the 2 subwoofers together, giving you a 4 ohm load. If you are going to run the subwoofers on separate channels then you need to get an amp in the neighborhood of 300W x 2 @ 2/1 ohms. Since your subs are dual 4-ohm VCs you need to wire the VCs of each sub together in parallel, or in series, depending on which amp you use. Parallel means the load will be 1/2 the impedance of the 2 VCs(2 ohms per subwoofer in your case). Series wiring means the load will be the total of the sum of the 2 coils together (8 ohms per subwoofer in your case). Amps make greater power with the lowest possible impedance, as long as they can handle the lower impedances (2 or 1 ohm).

Its better to have a large amp because you are less likely to damage the subwoofers this way, than say using say a 100-200 watt amp and overdriving it, causing the signal to clip. Besides, its very unlikely that you will be running the big amp with its gain adjusted to the max.

Personally I think that Kicker, JL Audio, JBL, Alpine, and RF make quality equipment...good bang for the buck at least. Just my $.02 :cheers:

Great post^^

 

I have had the most success with Fosgate amps being the most reliable/stable at 1 ohm.

 

 

 

I agree with you. My gf has the same two 10" subs that pacx12 has and its powered with a RF BD500 amp. Has been rock solid the whole time she has used it, and I know she cranks it a good bit of the time. Only thing I could add is that running a 1 ohm load on an amplifier generates more heat than say a 2 ohm or 4 ohm load. But then again, you are supposed to have the proper cooling space for your amp anyways. If you wrap your amp in a blanket to keep it nice and warm, then I suppose it will shut down from thermal overloads. :cheers:

The Profile AP1000 M may be a good fit for your setup. It produces 500x1 RMS at 2ohms so you would be running in parallel as stated by ranger203j. I have had this amp for over a year in a similar setup with no problems and it sounds great. The amp reviews well Crutchfield.com and if you purchase through millionbuy.com you can have it delivered for under $120.

 

I agree that Fosgate is probably one of the best but for my needs the profile works great and cost significantly less. Just my $0.02.

      OCI, not when but why?

      By PunchT37 · Posted

      When I was there, most to all did not have an hour meter. They just did 5000 miles on regular vehicles and 3000 on police stuff. The modern oil change monitors should take into account engine hours, weather, etc. I don`t use the monitor on my stuff. I pull the stick, look at it, smell it, rub it between my fingers, etc. That`s my oci.   I have had many engines. Some bracket race. No problems doing things my way. I was in the mechanic business for 30 yrs or so. I still do things the old school way. Don`t care who laughs at me.   Understand, I was in the main shop. We didn`t do oil changes or tires. We had a service station for that. I don`t remember the hours they used for tractors, lawn mowers, etc. Something in my head says 250 hours.

      I don't know how far back vehicles had hour meters, be it driver accessible or diag accessible but was wondering if there was any rule of thumb your shop came up with in regards to an hour limit on engine oil regardless of the miles on the oil.    I know with construction or farm equipment its almost always based on engine hours for maintenance scheduling as no other metric really applies other than a seasonal time limit that one self imposes on items like engine oil.

      I'm not sure what to say on that mess but I will say that is an odd thing for that mechanic to speculate on as per assuming its been run out of oil a few times as the odds of that engine having instead piled up with a complete seizure would be very high if such events had actually taken place. However there is nothing saying that the oil has ever been changed although once again, what filter was on that engine as that would tell part of the story if its possible to figure out if its a factory installed filter or not. Too many items unknown and a lot of speculation, but regardless of that its one fubared mess that is mind boggling to see for a vehicle that new and its hard to imagine how it ever made it that far in life looking at the top of the engine.    His scanners, I've watched him before here and there and I'd have to say if I recall correctly that some of his scanning equipment is one or two steps up from a child's Exo Sketch 😋

      I agree. That`s a LOT of sludge for 12,000 miles. I tossed that out here since this is an OCI thread. There`s tons of people here that do not post.   I used to work on a city fleet. That includes police cars and fire trucks. Lesson is, not to only use the odo for oci. A police car has a ton of hours on the engine for the miles it shows. And, not just idling, directing traffic. They beat on these things.   Course, since it is a Kia, they were gonna use the "100,000 mile warranty" for their OCI.😉

      Manufactuer's Defect - Paint Failure - Cherry Red High Country 2021 Suburban

      By AlVeron · Posted

      CLASS ACTION SUITS?  Does anyone know if there is already a class action suit for the paint - which was to have been fixed, changed in after the 2020 GM vehicles?  Does it look like this?    Just started 3 weeks ago - No help from GM as of yet - Dealer will not assist in speaking with GM on my behalf. Confirmed it is the paint they use along with the way the put it on that causes it to fail.  Clearly a Manufacturer's Defect.
