Wimpy blue tooth sound

Crutchfield customer from Florence, OR on 11/5/2020

I installed this amp in my 1969 Dodge Super Bee. The car has the stock,non working, AM radio only. I purchased this amp because of its blue tooth connectivity without the need for a head unit. I also installed a pair of JBL Club 9632 6x9 3 way speakers RMS 85 watts at 3 ohm. I was quite disappointed with the lack of volume and lack of fidelity, even with max gain adjusted on the amp and full volume on my phone. The sound was very flat, not crisp and very little bass, even with the crossover adjusted to its lowest setting. Out of curiosity I connected my phone directly to the amp via the headphone jack to the RCA cable connections. The sound was much better and closer to what I expected to get from the blue tooth connection. So now, to get good sound, I need to connect my phone to the amp using the RCA cables running through my car. Not the clean, wireless connectivity I wanted.

Pros: Easy installation

Cons: Wired connectivity using the RCA connections is the only way to get good sound.

This amp is the perfect size and the bluetooth works great. The installation is extremely easy and the directions were straight forward. Unfortunately the amp was not strong enough to run 4 MB Quart 6.5 speakers. Once you tune the amp gain pass mid way it starts clipping immediately. Had to return it. Customer service was awesome like always.

Pros: Size, bluetooth

Cons: Clipping
