Boss AMP liked this setup, but after almost a year of service, it blew up a channel. The Pioneer GM-D8704 had specs that fit my setup needs, so I got one. Let me tell you, this little 1200 watt pioneer blew up this boss’s door. No comparison, not even close. I had no idea how good the sound of these 6×9 could be .. in both loudness and sound quality.

The build quality is solid and can easily withstand all collisions with your car. Ease of installation and stability go hand in hand. it’s easy to control and comes with a number of features to describe the talent. However, over time, one or two channels may stop working.

2. Rockford Fosgate P600X4 Amp For Door Speakers

Rockford is also a big name in the music industry, producing a number of high-quality music products over time. This Rockford AMP can take input from more sources than most sources with input sensitivity ranging from 150 mV to 12 volts. If you have 8 tracks, you may want to consider this APM.

Rockford AMP 100w goes up like Alpine. I think both amps have enough power for infinity. it has good control. The parametric bass EQ lets me select the bass frequency I wanted to increase and then get a separate control to adjust the bass level as you wish. Perfect boom … but not too much to interfere with the rest of the music, but not really there. Boom All the harmonics that were missing in Class-D AMP are now back.

But unfortunately, if you have a 4-ohm speaker, it is not performing well and you will get only 75 watts per channel. Also, it’s a bit expensive. However, it compensates for the easy-to-use control.

4. MTX Audio THUNDER75.4 amp for door speakers

MTX is another brand that is brand new in the market, but it has made a name for itself in the market with great products like this. The Thunder Series 4 Channel AMP is the best bang for the buck AMP on our list. Through MTX, this AMP produces 100W RMS at 2 ohms and an amazing 75W at 4 ohms. This AMP is the best all-rounder with frequencies ranging from 15 Hz to 25 kHz, which is 5 Hz lower and KHz higher than any standard AMP.

It is the only other branch besides Alpine, with less than 1% THD. This deer is a bang for the buck. This combination brings a wide spectrum of mids/highs and lows to the vehicle. The factory makes Bose and Infinity stereos in my other cars. This amp is well spent, you won’t regret it. This little amp bangs! Run it on MTX terminators with power and it will pound the car. There are no extreme heat or protection mode discrepancies at the moment, just own this setup for more than a month.

This best 4 channel amp for door speakers is great. Its dead silence is a constant laugh in a cheap class D AMP without any music, which has no volume. It works well on power mids and heights. MTX is still great. As usual, some people do not know how to install a car amplifier and do not call it good. Have been using one for about 3 months and it’s a pleasure in my car. Set the benefit correctly and it won’t get too hot. Clip amplifier and improper gauge / using CCA wire is usually a crime if it gets too hot.

This AMP has minor noise issues because the S / N ratio does not meet the standard close to 76 dB. The frequency is 20-20 kHz. It stands at 2 ohms with RMS watts of 75 W and 4 ohms with 50 W, which is really impressive considering the price point of view.

I also tested this small amp in 3 channel mode, using 6.5 “coaxial L2 channels and the other two channels are the same 10” 4 ohm MTX Blue Thunder subwoofer. AMP looked very clean and dynamic. I was playing back FLAC files through my Canwood KML-BT312U head unit in my toolbox boom box. I bought this AMP toolbox to use in Boom Box, was very happy with the performance, I also ordered 300 double monoblocks, KDC-M3001. When I come, I will check it and report the results.
