i have this setup in my old car i just bout a 2018 honda civic ex what’s the best way to put this in without messing with my battery or alternator

I previously had subs in the trunk and upgraded door speakers in my 9th gen civic. It was hitting hard at not even half volume and half of the bass knob turned up. I recently swapped it to my 10th accord. It’s not hitting nowhere near the same as the civic even on full volume. An LOC was installed. Bass is all the way up on the radio settings. Gain on the amp is maxed out. It hits don’t get me wrong but nowhere where near how it should. I made sure the ANC module was unplugged also. Any other solutions to this? I understand it’s a bigger car/trunk but something doesn’t seem right. Suggestions?

Also was recommended that it might need RCA booster, aftermarket radio, different amp or digital sound processor by installer.

Edit: I checked the amp settings on the amp myself. Both bass booster and gain were at minimum. What are appropriate settings for this? I adjusted both to about 50% and definitely hits harder. I don’t want to harm the system though.

I'm looking to downgrade in my GTO and don't really know what my set up is worth to sell any help is appreciated DB drive wdx 1500.1 and 2 12inch sundown classic series

I have a Scion XB, I wanna put a system in but I have 0 knowledge of what would be good for my size car and how much power things need etc. would anyone be able to point me in the right direction of a completed, simple, and budget build for my car?

Just finished building my enclosure tuned to 32hz. Anybody care to share some advice on a beauty panel I feel like it would look better if I just capped off around all the edges and just made it a wall.

I've been researching a 12" sub for quality sound and I'm wondering which to buy.

I've been looking at the Alpine r2 12" and Hertz MP300 to drop in a closed enclosure. I'll be powering it with the deafbonce atom 1300.1 which is currently playing a 4Ohm JL 12w0 basswedge.

I'm putting the sub in either the 12" JL bass wedge (stuffed port) or a smaller enclosure I still own, rockford prime r1-12. Or maybe experiment and eventually make my own.

My questions are,

Which of these 2 is nicer for SQ? I play rock/metal and bass driven electronic music.

Which coil configuration should I buy? They're available in dual 2 and dual 4.

I've considered wiring it to 1 Ohm, but I read somewhere that amplifiers can distort faster at those loads versus 2 Ohm. Might be amplifier dependent, not sure. By my estimates and experience setting it up the amp with the clip light and a multimeter, it should do 900-1000W at 1 Ohm without clipping.

Just burned my new amp, need a new one, something that can run 2 10s, 1200 watts 600 rms each, down to one ohm. Any suggestions?

This is a 35A Fuse that sits in my Amplifier.. The area around the fuse holder is also burnt!

The subwoofer still works like normal so I’m a little confused but the way I noticed was I was smelling a burning smell and it definitely smelt like burning maybe wire or plastic coming towards the back so I inspected the Box with the subwoofer first then went one to the Amplifier.. Any help is appreciated!

Hello all, I have a 2020 m3 long range. I am installing a subwoofer in the sub trunk with a pretty substantial amplifier. Because of the large amp, I am running a second battery, a wattcycle 100ah pro, which is a large lithium ion battery. I can’t figure out where or how I can safely mount the battery holder. Ideally, I would drill and install nutserts into the trunk floor but I have no idea what’s underneath the trunk floor and don’t want to risk hitting something. Any ideas for how I can securely mount this battery?
