XKilley Posted January 17, 2021 Report Posted January 17, 2021 So, I bought a Pride AURORA amp and a Pride Tv3 15" and a Hollywood hc120 Battery but when I try to crank up the base it goes in to clipping fast. The highest peak was 90 A that got into the amp What could I do to get the maximum power out of my amp/sub? I also have an 70A alternator and a little 45 Ah Honda battery in the front I have one 0-gauge wire wired back to the trunk and a Sony MEX-N7300KIT Head unit.
EricM9104 Posted January 19, 2021 Report Posted January 19, 2021 your amp is pulling more power than your alternator and batteries can keep up with.... upgrade the alternator and front battery 2015 Honda Civic LX 4dr | 110k miles | Stock 1996 GMC Yukon SLT 4dr 4wd | 260k miles | JVC Head-unit
liteblue Posted January 19, 2021 Report Posted January 19, 2021 you did not list what you have your sub wired to If the sub woofer is wired to 4 ohms then you are getting max power out the amplifier, 900 watts rms at 4 ohm. wire down to 1 ohm. edit: love the remote turn on is away from the power by the speaker terminals. really nice touch.
XKilley Posted January 19, 2021 Author Report Posted January 19, 2021 Quote The woofer is wired paralel so it has 0.8 Ohms
liteblue Posted January 19, 2021 Report Posted January 19, 2021 what kind of battery voltage was the 90 amp reading? what kind of battery voltage when the amplifier is clipping? was the 90 amp on both 1/0 wires or just one? if just one then you saw 180 amps and probably rated power with box rise. Was this 90 amps on music or with test tones? sorry about all the questions.
XKilley Posted January 19, 2021 Author Report Posted January 19, 2021 It Was around 12.2Volts When it clipped it was around 12 Volts when the amp is off it has 14.4 Volts yes both cables are 1/0 and it was a test tone
liteblue Posted January 19, 2021 Report Posted January 19, 2021 were you clamping BOTH +12volt power wires? or 90 amps on ONE +12volt Have you measure clamped power out of the speaker terminals and then measured resistance of the sub during a burp? might just have crazy box rise.
XKilley Posted January 19, 2021 Author Report Posted January 19, 2021 yes i measured both cables and no i didnt measured the sub side ill do that tomorrow.
liteblue Posted January 19, 2021 Report Posted January 19, 2021 I would also double check and measure both wire individually. Make sure that both are showing 45 amps. Also, just a suggestion, if you have enough cable. Parallel the batteries directly to each other instead of at the Amplifier. If the batteries were the same size it would be cool but because they are different and you are connected directly to the terminals on the front battery you could be draining the crap out of that one and the rear battery has to fill the front battery to even everything out. Is that the original Honda battery? or is it less than a few years old?
