Avoid bending the power transistors leads once you remove the screws holding the circuit board from the heat sink. I suggest taking good (clear) pictures of everything before you pull it apart. This amp has huge potential, by design, but crippled by implementation. Replacing the twisted output wires with OFC similar temp rated wire or even untwisting the OEM wire can't hurt either. I would recommend replacing all the screws you remove because they will disintegrate on contact. Now whenever I play music at slightly high volumes it goes into protection mode and wont come back on until i restart the car. It use to work flawlessly (4yrs ago )but one day while bumping loud it kinda limped into protection mode. COBRA 29LTDCHR, deluxe classic truckers CB radio with chrome case Amp and. I have a Hifonics Brutus 1605d amplifier that goes into protection mode at Mid-high volumes. Note replacing the caps requires removing the amp circuit boards.which means disconnecting the heat sinks.lots of little bits, and heat sink paste. 95 Galaxy DX73V Cobra 148-gtl manual em portugues This mod package is for. The best choice would be splitting the required value over several small caps connected in parallel. Replacing these caps should put you back in service.Ĭap coupled amps sound bouncy.Pulses are accelerated and then fall off.So the choice of replacement cap will effect the tonal quality of the amp. The lower the impedance of your load (speakers) the faster this will happen. Therefore if you drive high currents of low frequencies the large caps will is a very graceful failure. The two large caps form a center tap for the power supply which is connected to the speaker terminal. And it worked!! There was probably a loose connection or an oxidized lead. Plugged everything back in where is was supposed to be, and turned the power back on. Everything checked out ok, so I turned power off. Use a multimeter to check the voltages coming out of those two power cables, they should be somewhere around 70Vrms.ġ0. Use extreme caution, there is live 120V leads in areas that you can touch with your hand! I recommend using only 1 hand while anywhere near a large voltage, incase of any shock, the current wont go through your heart.ĩ. Now the scary part: unplug the power cables (yellow and orange) going from the huge inductor/transformer to each of the amplifier boards, and then plug power into the amp and turn it on. Checked to see if any of the electrolytic capacitors had "popped tops" (if they had blown)Ĩ. Used a multimeter to check every easily accessible diodeħ. the thing is, i had an old amp hooked up and just upgraded so i pretty much just replaced amps and used the same wiring. Removed and checked continuity of the power connector through that fuseĦ. Get a multimeter test the voltage input on the power side, test the resistance of the subs, test the voltage input on the RCA', and test the voltage output on the channels. Removed and checked the two fuses on each of the amplifier circuit boardsĥ. Removed and checked the front ON switch for power continuity (with power turned unplugged, just use a multimeter on continuity check.Ĥ. Plug it in to make sure it doesnt just turn on, it didn't so unplug itģ. Pray that God would be glorified through anything I doĢ. You could bring it by my church either this coming new years or this saturday night. Is there a way we could meet up and I could take a look at the amp for you. The amplifiers protection condition is also shown by blue illumination for normal operation and red for a short being present and requires the attention of an installer.I happen to live in your area. All Mono and five channel amplifiers include a bass remote to put the bass control at arm’s length. This keeps power smooth even during demanding peak in the music. The rock solid Ultra-Fi™ MOSFET outputs are selected for both balance and output power. it's been tested, and it truly puts out 1324 watts at 1 ohm. this way at that volume your head unit is at, every part of your system is playing as hard as it can. leave your remote turned all the way down and do the same with the gain on the amp. take the number of actual watts the amp can produce at your given ohm load, multiply that by your impedance (ohm load), and then find the square root of that number. the general rule is to turn your head unit up slowly until you get distortion out of your speakers then back it off until the distortion goes away. All our reviews have come from real guests who have stayed at the property. here's how you figure out what to set your amp to. The BXX4000.1D is a 4000 watt mono amplifier featuring Super Class D™ technology with an NGSD digital chip to provide you with an extremely efficient, low temperature, high amplification system that others only dream about.
