Unless you turn up the volume too much, you will feed the speaker, but watch out for the loud sound, the outputs of the tape may be damaged.

I always recommend a compenant suit instead of an oval. Although it is an ancient tradition, ovals are now the era of era comp. Maybe there is a price difference, but the sound difference and quality you get will not be discussed. Bass and twit kill each other, you can perceive neither the low nor the high frequency, the middle disappears without any existence.

I will show you an example of my own vehicle. The hpf setting of two of my amp's stereo channels wasted, so I put it into the service so only the ovals on the back (2-way pioneer 6973 400w) are fed from the tape. Believe me when I turn up the sound, I regret it. If I turn on the bass, the treble dies. If I put it on the treble, it feels like a moan from behind.
I have infinity mid sets on my doors, the sound setting is 5 and the quality is the same at 62. I get it in treble, I get it in bass. If my head hurts or is uncomfortable, I turn off the bass from the tape. Even the mids of the stomach is enough.

teacher, what do you mean by the compenant team..they say loudspeakers on the front doors..mid treble team they say 2 tweter and 2 front door speakers
