My folks have an old subwoofer in their home stereo. The plate amplifier on the back of subwoofer cabinet seems to have died. I was gonna buy a replacement but the replacement size isn't identical. I'm sitting on 2 subwoofer amps from my car. 1 300w @ 4ohm Alpine and 1 500w @ 4ohm Kenwood...

Looking at picking up a 10" Kicker L7R 4ohm sub, but wondering what amp I should get to pair with it, and if it's worth getting a 4ohm or if I should just get the 2ohm to make life easier. I have a 1997 Acura Integra that I've been moding to be a daily driver for the past year, and want to add...

I've posted about this topic a couple times already, but I have yet to find a solution. I installed an after market amplifier to power my mids and highs. I already have a sub amp that isn't having the same issues. My stereo is a JVC KW-M780BT. The amplifier powering the whine is a Infinity...

I am rather new to car audio so excuse my lack of expert vocabulary. I installed a single 10 inch subwoofer box, and all new JL door speakers and dash tweeters into my 2020 Silverado 1500. Everything played great for awhile but I started to hear a popping / scratching sound when I turned the...

I'm adding subs to my 2003 BMW Z4. I'm an electronics engineer but don't really play with audio much. I'll be using the factory subs which are 2 ohm. I can easily get the audio from the existing rear speakers and feed it to the amp. I'd like the audio feed to turn the power on at the amp if...

I have bought a car with a very professionally installed Kenwood system from the early 2000s I assume. The issue i'm facing is in the Kenwood KAC-8404 Amplifier. For some reason the A-channel only output on the right speaker. The mono switch forces audio to the left channel and so there is no...

Hello guys, I bought today a 4 channel TRF M600.4AB amplifier and dont know what fuse to use for power cable. On the internet i have read that because my amp has 2 fuses 40 amps each, i have to use a 80 ampere fuse. But my amps manual says that i need to use a 40 ampere fuse. What is the right ?

Hello I’ve had my audio setup for a while now with no issues until last week. Went to leave my house and car won’t start because the battery is dead. Figured I had a bad battery because it was pretty old so I got a new one. Next day battery was dead again. So I unhooked my 2 amps and jumped my...

I have a Skar RP-800.1D, it is a monoblock with 2 sets of speaker terminals. I know that this is for easier wiring/ more space for wires. My question is when I wire this into my DVC sub, can I just run + to +, + to +, - to -, and - to -, and would this end up as parallel wiring? -For any...

This question may be quite straight forward, but I cannot find an answer anywhere. I am new to this forum but I found the formula to ballpark estimate my total amperage. I do not understand one part.

Greetings to everyone! Guys, just a simple question regarding amplifiers. I bought a 500w amp, 2-channel bridge. So, do I have 500w on each channel (for 2x 500w speakers) or I should consider the sum of both (for 250w speakers)? I bought 2x speakers, for rear only (Alpine SXE-6925S, 6 x 9...
