User questions & answers

Question:	I have a couple 6x9 and a box with separate chambers for 8” subs any pros or cons
Answer:	The amplifier runs warm in high pass so it will probably run hot but does have thermal protection circuitry and will reset but wouldn't advise running it like that!!!
Question:	It quit working with in 10 minutes. It has a red fault light not green. I disconnected the speaker wires killed power turned on still red . What to do
Answer:	Make sure power lines and especially a ground wire is hooked up properly. That's the main thing ground is very important that's actually touching metal the car itself. And none of the speaker wires are shorting out
Question:	Does this amplifier support bluetooth operation
Answer:	No it doesn’t..... I bought this same 1500 watt full range amp and tried to get in touch with Blaupunkt for some tech questions I had, GOOD LUCK WITH THAT!!!! Apparently Blaupunkt amps are not associated with or made at same place as All other Blaupunkt audio units & products, search it on internet
Question:	how many true watts does a 1000 x 4channel amp actually put out
Answer:	I'll post a link to a youtube video where this amp was put on the Amp Dyno but if you don't feel like watching it the results were 65- 71 per channel (cea certified) @ 4 ohm @ 14.56V. Keep in mind those numbers will drop when an amp is installed in a car because your only going to about 13.4 to 13.9 V to the amp and that"s if everything is the right size and grounded properly. As a rule of thumb a single 30-amp fuse means that the amplifier can produce 300 watts of power at most. A60 amp fuse will make 600 watts plus or minus 10-20 depending on the quality of the amp. The quality of this amp is crap it may have 2 30A fuses but makes no where near that power. At 2 ohms it makes about 100 watts per channel. The 2 30A fuses making 600 watts doesn't account for the total efficiency. This amp is about 70 efficient which is awful ! If you plan on using this to power 4 door speaker at 4 ohms 65-70 watts it will work just fine because guess what those 6.5" 500 watt speakers lied about the power handling too. If your not very familiar with car amps and want to know if your getting a deal or ripped off watch this guys videos, https://www.youtube.com/watch?v=FbA2Vdg3uSo thats for this amp and 2 other Bloujunk amps. If you're looking for a budget amp that puts out like a prom date, 1100 watts @ 1 ohm (2 ohm DVC sub) for $104 check out his video of a dyno drag race the Ignite R3000/1D vs the 2nd best budget monoblock amp the BOSS AR4000D. https://www.youtube.com/watch?v=UvHWxhm7Eog&t=630s My advice buy the Ignite and the warranty Amazon sells for $20 so you know your going to get 2-3 years of worry free ownership.

User questions & answers

Question:	Does the R500x1D come with the remote or is it sold separately
Answer:	It comes with the remote. I thought it didn't so I bought one for it and it already comes with it so I have two now
Question:	Does this amp provides High (Speaker) Level Inputs so it could be connected to a factory head unit
Answer:	I know this is late, but it may help others. Yes it does and you can tie into signal at rear speaker wires. The built in crossover will allow use of a sub woofer. Only drawback to this set up is that if you turn down head unit bass for doors ect. it also affects sub amp. HU built in crossover would be better for a balanced and more adjustable sound. This requires the HU to be upgraded however. A line output converter is a good option too even if you have low input ability. Makes for a neater install IMO. Bottom line is that it is dooable. Good amp too. Birthsheet is 648 watt @ 2 ohm 14.4 v on mine. In vehicle at idle in real life I average 629 using amp draw and voltage formula, I also own the P300-1 which pushes about 415 @ 2 ohm real life wattage. Birth sheet of 426. Banging for years in wife's ride on that one no issues. The new one rocks good so far in my ride. Love these amps. So much power for the size. Also as a D class amp they are efficient and take less away from the vehicle power system causing less strain. Bang some high power AB amps for a few years and your whooping on that alternator and battery shortening their lives. Less light dimming too.
Question:	Does this amp have an auto turn on feature so I dont have to wire up a remote turn on
Answer:	Another option in which I chose since it does need turn on signal is to use an added retained accessory power relay or just a simple relay. Your going to remove side panels to run RCA anyway so tap easily into a 12v power source when vehicle acc is on which can be found closest to amp position that is passing to rear of vehicle already. I used this one from Radio Shack. Model: 275-233 Catalog #: 2750233 0.5-AMP SPST REED RELAY AT 12VDC. This set up should be used to turn on multiple amps and relieve the head unit circuit. No tiny wire to run either. Although if this wire is just attached to RCA prior to install for a 1 amp install then this is the easiest way. If you use the relay then remember to fuse it to protect the head unit circuit.
Question:	is this amp 4 or 8 awg power and ground
Answer:	It has 4 awg connections for both power and ground. I am using mine with 8 awg wire and it runs perfect. I am not running it at max gain though. Only using it to run one 10" L7!

User questions & answers

Question:	My receiver has 4 RCA outputs. Can I run the 4 RCA outputs into this amp and run 4 coaxial speakers plus a subwoofer
Answer:	Yes you can. There is a switch on the amp and it will take the sound from channels 3 and 4, and use it for the subwoofer.. so you dont need a 5th rca cable.
Question:	What is the RMS
Answer:	Taken from Google: RMS stands for root mean squared.You use RMS to tell you in part how loud the speakers are going to be, you also you its sensitivity rating.RMS also tells you the most amount of watts that you speaker can handle on a continuous basis. This is the figure you use when looking for an amplifier and powering the speaker.1000w RMS is a lot and i would be very skeptical buying any speaker that says it handles 1000w RMS, most companies that put out a speaker like that inflate their numbers by making the THD level higher so once you turn it up the signal is not clear. Also they will make it 1000w RMS but its sensitivity rating is very low such as under 80db/1w.i know i have two JL subs that are rated at 300 watts RMS each and the 600 watts it puts out is enough to make me go deaf.
Question:	I have a kicker 10" sub with 4 ohms, but when I hook it up to the amp I get absolutely no sound out of it. The first four channels are running fine
Answer:	There is a switch near the sub control on the amp.. direct or channel 3-4. If you do not have a sub input the switch should be set to 3-4. So it will get the sound from channels 3-4. . Hope this helped
Question:	Will this amp be suitable for 2 pairs of Pioneer TS-A6885R Speakers 350W (60W) nominal and TS-SWX251 Subwoofer Power(Nominal)800 W (200 W
Answer:	It is extremely important to understand Ohms law when choosing speakers. One answer on another question says it is not 2 Ohm stable. They wouldn't make the UL list if it didn't. The fifth channel is 1 channel that is 2 Ohm stable. It can handle 2 single voice coil subs wired in parralel which brings the Ohms down to 2 Ohms. I do not recommend DVC in a mono amp unless the amp is 1 Ohm Stable. If you got 2 DVC subs wired parralel would present a 1 Ohm load to your amp and blow it up.

Product description

It's an increasingly common problem. You can't replace your vehicle's premium factory radio, but the premium factory amplifier isn't powerful enough for you. Furthermore, the factory amp gets digital information from the vehicle's databus and replacing the amp would mean you'd lose all audio control, like volume and balance, as well as other features like steering wheel controls, audible navigation alerts, warning chimes, and Bluetooth connection. Replacing the factory amp with Kenwood's Excelon P-XR600-6DSP amplifier along with its included iDatalink Maestro amp replacement module adds a huge amount of power and tuning ability to your system while retaining all of the vehicle's audio and communication functions.

Answer:	I have four of them 6by8 200 watts n a 400 watt sub 8 sounds ok with out the amp in a town car ....but will this amp push all 5 speakers??? Those come in 300 watts 6/9 ...and 200 watts 6/8
Question:	Will this power 4 100 watt 6x9 and a sub
Answer:	2 months ago I hooked this amp up in a 66 mustang a pair of 6x9 and 3.5 on channel 1&2 using the high pass filter and a pair of 10" Crwin Vega DVC wired down to 2 ohms each. one on channel 3 and the other on channel 4 using the low pass filter. I was very surprised by the sound. Great bass sound and clear sound. It is not competition grade by any stretch of the imagination, but it does give some great bass sound and rattles the mirrors. i was waiting to write a review until it had some time to prove itself. My friend is very happy with it, doesn't want a second amp for bass. Use the right size power wires and you will be happy.
Question:	How many ohms per channel
Answer:	4 ohms, but it's 2 ohms stable and is okay to hook up that way, according to the directions.
