Frequently Asked Questions - BXA1-7500D Soundstream
Can I bridge this amplifier to run a single subwoofer?
The BXA1-7500D is a mono block amplifier, so it is already designed for a single subwoofer output. No bridging is needed.
What is the recommended speaker impedance for this amp?
This amplifier is stable at 1, 2, or 4 ohms. For maximum power, use a 1 ohm load.
How do I set the gain properly?
Set the gain using a multimeter or oscilloscope to match your head unit's output without distortion. Start with gain at minimum and increase slowly.
What gauge power wire should I use?
Use 4 AWG power and ground wire for runs up to 20 feet. For longer runs, use 1/0 AWG.
Does this amplifier have a remote turn-on lead?
Yes, it has a remote terminal (REM) that requires +12V signal from the head unit or a remote turn-on wire.
What type of fuse does it require?
It uses a 60A AGC or ANL fuse (check your model). Replace only with the same rating.
Can I use this amplifier with a factory head unit?
Yes, but you may need a line output converter (LOC) if your factory unit lacks RCA outputs.
How can I protect the amplifier from overheating?
Ensure adequate ventilation around the amplifier. Do not mount in enclosed spaces. The amplifier's thermal protection will shut it off if it gets too hot.
What is the subsonic filter for?
The subsonic filter removes ultra-low frequencies (below port tuning) that can damage subwoofers. Set it 5-10 Hz below your enclosure's tuning frequency.
How do I clean the amplifier?
Use a soft, dry cloth to wipe the exterior. Do not use any liquids or chemicals.
