Review: I didnt get the warrant for this and the thing doesnt work now - What can i do for its just 4 months
Review: Gran bajo para algo pequeño - Muy buen bajo para mi Jeep TJ. No requiero más. Es importante mencionar que la instalación sea con RCA, la respuesta del bajo es enorme que con la instalación vía cable de alta. Quieres un buen bajo, compra un set de instalación para subwoofer y verás la enorme diferencia. Además proteges más el equipo pues trae un fusible para el cable de que va a batería.

## Questions & Answers

**Q: Can I wire the input from the rear left/right speakers and then wire them from the amp ?**
A: Yes it can come from the rear speakers it has an amp. you need 12V power. just need LFT Right wire. 
amp wont boost your OEM rear speakers, amp is only for the blaupunkt speaker.

**Q: How many Ohms what's the impendance?**
A: This information isn't listed, not even on Blaupunkt site.

**Q: Does it good enough for single cab truck with 4 channel stock stereo ?**
A: Fits under the seat. Requires good sized wire for 12 volt power and a ground. comes with a volume trim controller if you want to use it. 
good base narrow clearance under seats.

**Q: Do this amp turn on using the hi level input? And not the remote trigger?**
A: Not sure if it has the auto turn on feature.  You can try it without the trigger wire and see if it turns on.  If not then you will have to wire the trigger wire to something in the  fuse box that is only on when the ignition is on.  Otherwise, the battery may be run down.

### ⭐⭐⭐⭐⭐ Great bang for the buck
*by S***L on 1 May 2022*

This one performs far beyond my expectations. Bought this as an experiment to see how well it would fill the low end of the sound system in my extended cab F250. I wasn’t looking to fill the entire back seat with an enclosure etc. and figured I’d give this a shot. After a bit of tuning this completes the system perfectly. It has a great range of bass and sounds amazing. I didn’t expect it to have even half the power and volume it has. Highly recommended if your looking for big bass in a small package. It’s slim enough to fit nicely under any of the seats and not be in the way. 100% completed the system in my truck!
