Why wasn’t this type of amplifier developed years ago?

The following review is for KTA-450, which is a part of the bundle you are viewing.

This is a fantastic little amplifier, but it’s not flawless. On the plus side, this thing really does deliver amazing output for its size, and the convenience of strapping it on to the back of a mechanical-less Alpine head unit is ingenious. The only real downside is that you have to adjust the gains before you mount the radio, because once it is strapped to your face plate and screwed to the mounting brackets, the gains are no longer accessible.

Great product

The following review is for KTA-450, which is a part of the bundle you are viewing.

The small amp that fits behind the Alpine double din radio mounts right to the back of the radio for easy installation.

Far Exceeded My Expectations

The following review is for KTA-450, which is a part of the bundle you are viewing.

I wanted a small to boost my system with smaller foot print amplifier, that I didn't have to run wires into my doors for the speakers. After my research I came across this amp you what sold me was the (DDP) DYNAMIC PEAK POWER. Let me tell you this amp gets loud and stays crystal clear. I have the KTA-450 hooked up to JL Audio C2-690tx's. this set up is phenomenal. If you're thinking about this amp DOIT you wont be disappointed much louder than I expected and will pierce your ears if you max out the highs lol.

Great OEM Upgrade!

The following review is for SXE-1726S, which is a part of the bundle you are viewing.

Replaced the OEM speakers in the rear doors of my 22 WRX. Paired with the SXE 6x9's they sound great! The lower RMS makes them perfect for using the OEM stereo without an external amplifier. 100% recommend.

GREAT OEM REPLACEMENT!!

The following review is for SXE-6926S, which is a part of the bundle you are viewing.

You can't beat the price. My vehicle (22 WRX) came with 6.5's in a 6x9 enclosure. Swapped these out and it sounds 10x better. The lower RMS made it perfect for using with the OEM headunit and no external amp. Very punchy, and hits bass perfectly. Would definitely recommend for any OEM upgrade.

Absolutely amazing sound quality ????

The following review is for KTA-450, which is a part of the bundle you are viewing.

I am blown away by this amp, which is installed in pair with the Alpine ilx-650 headunit. So nice that it fits behind the radio in dash, wiring was a Breeze. Installed in a 2007.5 silverado 1500. Absolutely blown away.

Alpine SXE-6926S

The following review is for SXE-6926S, which is a part of the bundle you are viewing.

Excellent product, at first I was concerned about fitting on my 2016 Town & Country Minivan (Rear speakers) and yes, fit perfectly. it'ss not touching the car metal.

Pro: Great quality, clear sound. I have an alpine radio and the bundle really makes a good sound experience.

Cons: It does not come with speaker wires, I would recommend buying the aftermarket speaker connectors
