Does anyone know how much is a acousticmax hd70 is worth todays is it a rear speaker?

Contact Acoustic Solutions directly to request the manual.

It is an indicator. It indicates the power.

A Bad Connection at the Power, Ground, or Remote Wire is likely. If it’s overworked it’ll shut down before you’ll smell it or see anything glaringly obviously, adjust the gain level down to lighten the load on the amp and see what happens. Make sure you’ve got enough amp. Subwoofer Specs & Impedance would be helpful.

Also, insufficient voltage to the amp will cause that, make sure your power wire and ground are large enough, use 4 Gauge Minumim but I use Zero Gauge for max voltage transfer and feeding the amp with all of the power it needs. Wiring is an issue. Also be certain your alternator and battery are healthy. Upgrade them if necessary, adding a 2nd alternator is simple, a large derp cycle battery(optima yellow top) is worth its weight in gold! Do the big 3 upgrade, google this, it’s just upgrading the wiring from battery to starter and alternator, plus using a larger ground wire to ground engine to frame/body. Huge Difference In Performance & Reliability of power supply to be had and simple for anyone to do with general knowledge. Good Luck!

P.S. I’d run Zero Gauge to your amp ASAP. Just my opinion, ask a few local scorers in the car shops and stereo sections!

use a quality condenser cardiod or super cardiod microphone not cheap dynamic mic esp omidirectional. speaker in font of mic. keep gain on mic to a minimum. do not use mic speaker assembly that the mic and cable are one piece. try to point speaker at hard surfaces as these reflect the sound back

Please type the "acoustic solution ds1233" into the search engine of your computer, and a lost of dealers, and maybe even the factory , will pop-up so you can find the part you are looking for. God bless your efforts.

Use the rotary Tune/Select control on the HiFi itslef, or the two triangle buttons on the remote control to highlight each mode option until it goes to DAB Radio or FM Radio. Short press the Tune/Select control on the HiFi or the Select button on the remote control to select the option. If that works, the manual at the link below is compatible with your equipment. http://documents.4rgos.it/v1/static/7347948_R_D001 http://documents.4rgos.it/v1/static/7347948_R_D001

My personal suggestion would be to go for these repair catalogs. I know this website reliable-store.com that i used to buy them from, and they have online it was very good manual. Go ahead, I bet.

The power acoustic BAMF is a really good amp if that’s the amp you are referring to. If you are wanting to go with power acoustic subs the mo fo would be the way to go. The mo fo is an amazing sub. If everything else is going to be power acoustic you might as well stick with that. Power acoustics has some good head units as well.

Re polarity - the diode should have a band nearer one end. This band is the cathode. Usually labelled k in schematics. The un-banded end is the anode. Usually labelled a in schematics. On a standard rectifier diode: The positive + supply enters the diode at the anode and exits at the anode. However, the component's ID is ZD3, which tells me that this is a Zener diode. A zener diode is connected opposite polarity to a standard rectifier diode, as it only conducts when reverse voltage from k to a exceeds a pre-determined level. This is probably part of a voltage regulation or voltage clamping circuit. ie: when voltage on 'k' line which is positive goes above 'X' volts the zener will conduct, shunting voltage to ground or another part of circuit. So on ZD3, band is +. A new diode is advisable, as it serves as over-voltage protection. The caveat is what voltage rating of zener diode you will need. A schematic of the sub will be needed to know this....
