Feel the Punch!

The Punch P400X4 multi-channel amplifier is versatile to power any audio system configuration. In addition to 4-channel stereo mode, you can bridge both channels to create a high power 2-channel amp, or run stereo speakers on the front with subwoofers on the rear in 3-channel mode. The variable HP/LP crossover and built-in Punch EQ allows for precise tuning of Bass frequencies and the Pass-Thru RCA jacks provide flexibility as your system grows and keeping Y-adapters to a minimum.

Solved that static alternator whine issue

The following review is for XFLOC4, which is a part of the bundle you are viewing.

My brand new car's factory sound system sounded terrible so I decided to upgrade it. I had to keep my factory radio because the car's functions depend on the screen/radio of the car. I installed a JL audio 300/4v2 along with Focal components and after I was done installing everything, there was a tremendously loud static noise coming from the speakers, even with the volume all the way down. When I would rev up the engine, it would make a whistling, whining noise from the alternator. I spent 2 days trouble shooting the problem. Separating wires, re-grounding, running new wires, adjusting gains, etc. and none of that worked. I saw this LOC from NVX and decided to give it a try since it claimed to have a digital noise filter feature. Man, as soon as I installed I was blown away. That annoying noise was GONE! The music sounds crystal clear now. I purchased that particular set up because I wanted an SQ sound system and now it delivers that very clean music with absolutely NO distorting noise. I was stressed out for 2 days wondering how to fix it. If you are in the same situation, buy this LOC. It will end your problems with all that unwanted noise. Forget those "solutions" people talk about all over the internet about re-grounding, ground isolation, and all that junk. This LOC solved it for me. It was so easy to install, it has adjustable gains, and feels very sturdy. Even if you turn the gains all the way up on the LOC, you will still hear no unwanted noise.

perfect!

The following review is for XFLOC4, which is a part of the bundle you are viewing.

No unwanted noise, soft turn on and off, cant even tell its there. It does its job seemlessly in my 09 Jeep Grand cherokee with boston acoustics system. I wanted full range sound out of the door speakers so I pulled off the output from the factory amp of the dash speakers and rear speakers. All speakers are now full range and amplified with a kicker ZX350.4. I can keep the gain super low on the amp and cross over the speakers to keep the bass out with the amp controls. This LOC made all that possible to use the kicker amp with NO NOISE.

The following review is for XFLOC4, which is a part of the bundle you are viewing.

Durable, small, easy to use, fun, quality build and sound! Great LOC! No unwanted noise! Love the gain controls and remote turn on for an amplifier! Works wonderfully with my NVX JAD900.5 and my NVX 4 channel rcas! NVX is the only way to go! I just can't get enough of NVX! Thanks NVX and Sonic Electronix for all of your support!

The following review is for XFLOC4, which is a part of the bundle you are viewing.

I used this to convert wired to RCA. This device worked great. I eventually replaced the factory head unit with a Pioneer that had RCA outputs.

Worked great!

The following review is for XFLOC4, which is a part of the bundle you are viewing.

I installed this unit on my boat due to my radio had to pre amps.. Easy to wire although theres a bunch of wires. Works great for triggering your amp though! My radio put out 160W so I left all my channels on the unit turned down. Would highly recommend!

Great Buy!!

The following review is for P400X4, which is a part of the bundle you are viewing.

I purchased this amp to run 4 Pioneer TS-A6995R 6x9s in my 2002 Toyota Camry. I upgraded all my speakers from stock and purchased this amp & I've noticed a huge difference!! I love the settings this amp has to offer, sleek design, but most importantly, it's CEA-2006 Compliant. Normally rated at 400w RMS, my amp came rated at 568w RMS!! So at 4ohms, I'm pushing around 84.75w RMS per channel, which is how I have my speakers wired up. At 2ohms, it pushes around 142w RMS!! I would definitely recommend this amp to anyone looking to upgrade their stock speakers and need an amp that's gonna push!! Also, this amp was small enough for me to fit it on my backseat between my secondary battery and my other amp for my subwoofers.

Awesome amp!

The following review is for P400X4, which is a part of the bundle you are viewing.

This amp is a great amp. It was a great buy and the built in clipping detector is awesome!. This amp I had on a set of rockford door speakers and the sound quality was amazing. The only thing is it doesn't have outputs. If your looking to get this I would recommend just getting the punch 600 4 channel so you got the extra power if you ever need it and it has outputs. If you don't need the outputs or the extra power this is still a great amp to buy and I recommend!
