Replacement amp for a burned out JL amp
Robert B on Jun 8, 2016
These amps are considered a great deal in the world of SQ car amps.
James T on Mar 23, 2016
Reviews on this were good, i was surprised when i installed it, that the sound quality exceeded my expectations. At the price I didn't think i could go wrong...the reviews are true about the strange connection terminals with a bar in the way and the manual is all but useless, particularly if you are looking for the proper way to bridge the 4 channels.
Beau L on May 7, 2016
Compact Size, Power Ratings I was looking for, and this amp has many favorable reviews for its price point. I actually purchased two of these. One for my left side and one for right side.

Can I the 4 channel at 4 ohm and the subwoofer at 2ohm with this amp?
Chris S on Oct 15, 2014
Best Answer: Yes absolutely. I have the 4 channel half running at 4 ohms on all my 6x8s and the sub channel is at 2 ohms on my two 12s and it barely gets warm. I've run it hard everyday since April with no issues.

How do I run a 4 ch amp and a 2 ch amp off of only 2 RCA outs from my head unit? I have a clarion m502 and want to run a PPI P900.4 for my 4 cabin speakers and a PPI P600.2 bridged for my subwoofer.

Best Answer: Hey Darin, first you need to get two 1-male to 2- female connectors( and attach them to each of the rear RCA cables on the rear of your Clarion head unit. Next you will connect your P900.4 to the front channel like normal, and connect it to the rear like normal, only you will now have 2 extra RCA cables left that you will use to connect your 600.2 with. I hope this is clear enough to answer you question

What is the "source' switch that has choices for "int" and "sub" for/do?
Sean W on May 14, 2016
Best Answer: looking at my manual, it doesn't give specifics on that circuit. But from my year's of car audio experience. What I believe is, if you only use the front output from your receiver to connect to this amp. You would insert your RCA cables into the front input RCA's of the amp. You would then select ST for *input select (#3 in manual). Then the source would be set to INT.

If you put a parametric EQ in between your amp and receiver like I did to have more control and quality sound. You would connect the receiver's front output RCA's to the EQ front input. From the EQ, it has dedicated RCA's for front, rear, and sub. I use all three sets of RCA's from the EQ to connect to the amp instead of just one. I set the amp *input select to 4ch and set the source to sub because the sub channel of the amp now has its own dedicated signal from the EQ. Where as in the before setup, you have full frequency range coming from your receiver to the amp through the amps front input only. The amp has a small built in 3 way internal crossover that splits the frequencies when you select Int for the source. It basically gives options for system building. Using my method gives a lot better sound quality because I'm using a much larger 3 way crossover ( my parametric EQ). Hope this helps

how do I connect 4 gauge wire to amp?
Jim W on May 22, 2015
Best Answer: from what I remember, the amp comes with a 4 gauge adapter that plugs into the power, ground, and remote using gold plated posts. This adapter looks like a three pronged block that you then use to plug in 4 gauge power and ground and your remote wire, which remains its standard 18-22guage size. This amp is amazing, i could not be happier.

I have four punch 6x8's and a punch p1svc4ohm 12". Will this amp do the trick? I currenty have a prime 250.4 running the 6x8's and they don't sound too good. The p1 is extra from another setup not currently being used. I would like to just use a one amp setup.
Jason L on Dec 21, 2014
Best Answer: it may have been wise to purchase a dual 4ohm voice coil sub so you could wire it parallel bringing the ohm load on the amp down to 2 ohms. that way you would have achieved 440 watts at a 2 ohm load instead of 270 watts at the 4 ohm load you are left with now. not sure where/when you purchased your other equipment, but when planning a system it is always wise to think ahead, map it out, and really contemplate how all of your components are going to interact and work together. that being said, your sub is only rated at 250 watts RMS, thus running it at 4 ohms should be just fine, in fact, even preferable since it should have a little less distortion and will be easier on your amp (and it will run cooler). you could probably get away with running two of the subs you have (2 single 4 ohm drivers can be wired parallel into a 2 ohm load). the RMS rating would be 500 watts, and you'd be pushing 440 but that's just fine. Again, it will push your amp a little harder, but this amp is up to it. trust me. I am running a 10" 4 ohm DVC Kicker L7 and that is rated at 600 rms…. and it sounds amazing.

Does anyone using this amp have the need to use a farad cap? I have a 2.0 farad cap I bought for another vehcle that I never got a chance to use, and was wondering if anyone had the need to use one with this amp.
A shopper on Apr 10, 2015
Best Answer: Hello,

We just wanted to chime in with a quick note. Your question is far to relative to get an answer that is going to suite your application. There are way to many variables involved and no install will be like yours. With that said, we hope you are asking if the Amplifier has the need for the Cap, not the Vehicle. A vehicle doesn't benefit from a Cap, the amplifier does. It just so happens that a vehicle will sometimes benefit from the caps ability to hold a quick burst of energy and so forth. Nevertheless, it is unlikely that your vehicle , unless a very small one, will lack the power needed to run the amplifier. If you fear it does have that lack, then upgrade the battery, don't add another load in the form of a cap. Keep in mind, the vehicle will need to recharge the cap AS well.

I purchased the PPI 900.5 on 5/27/15 I installed on 6/22 I used Stinger RCA Interconnect Cables from the HU to the amp for the 4 channel output and the sub output all the 4 channels work, but the sub channel you can barely hear. I double checked all the connections everything is ok. I previously had a PPI S320.4 Sedona amp that I used to bridge 2 channels for the sub and it works fine. Is there something with the 5 channel amp that I am not doing correct? Thanks for any answer.
