Hi there. I installed a subwoofer in my car using an RCA converter I purchased from WOW sight and sound. I grafted the RCA converter up to the rear speaker wires (like it said to in the instructions) and then the RCA leads from the converter and into the amplifier (im using a 4 channel amp to power my sub btw if that makes any difference).

I've switched the amp to use the LPF (Low Pass Filter) setting on the rear channel and have put the gain and LPF knobs to half way and the bass setting to 2 (out of a possible 5) on the stock headunit. The problem is that whenever I have any sort of punchy bass the subwoofer doesn't kick, it vibrates or fuzzes instead. What have I done wrong and what can I do to fix it? Im hoping all it is, is that I need a new sub coz the coil might be stuffed or something...idk. I just want to have a good amount of bass! I've tried setting the LPF switch to -12, -6 and 0db settings and the fuzz is still there regardless.

So yeah. Pleeeeaaaasssee help me! :blink:

Hey mate. Yes, it sounds like your sub may be dead, best way to check it is find someone else with a sub and hook it to your system, had a cheap audio-bahn sud die on me once, did the same thing ie. higher frequencies were ok, but good strong hits sounded nasty and made the amp cut out. Also, is your RCA converter adjustable? As if it's turned up too high the signal would be upsetting your amp. More info please: What amp do you have? What sub is it hooked to? Did you bridge the four channel amp or are you running it off one channel for the moment? Is the gear all new or 2nd hand? And did it work before you hooked it up as it is now? :ermm:

Either your sub has had it, or it may be a case of checking your earth mounts. If the sub is on it's way out it may pay off to get some one else sub and see if it does it with there's

there can be other issue's which is why I thought you should call chris.

the list is long on why it does it , and if he is close or has time to listen to it on the phone much easier to sort that way.

doubt the sub is dead unless the voice coil is burnt on it.and dragging on the coil gap. a tensil lead can be hitting a the frame on the sub, the list is huge

before doing your head in just call chris

Sounds to me like the gain is too high

What is the brand/model of RCA Adaptor?

If the RCA converter has adjustable gain, turn the gain down.

The Cheap RCA converters are not the easiest things to make sound good.

Also before trying one of your mate’s good subs in your car and possibly damaging it. I would be trying your sub in someone else working setups. Just a thought…….

      Jacks that fit under GTR lips that can reach the subframe?

      My dream is also to have a proper hoist, but I don't think it will ever happen. My quickjack is probably as close as I'll ever get, it really is very good though.

      Duncan's V37.......race car?

      Yeah we keep on in the dailies, it is pretty poor how many animals get hit and the driver leaves without checking....have saved a couple of little ones over the years. Bit of a gruesome job though, pouches generally need to be cut open because they are so tight and often the joey doesn't realise mum is gone so they are still locked onto the teat. I checked the modules in front of the DS wheel where an oil cooler should go.... There is the radar unit - that can go for race use) One of the 2 HX water pumps, the silver cylinder. That needs to be kept but might be able to be relocated But the bad news, the big computer mounted vertically in front of the wheel (blocking any potential air exit) is the electric steering computer. That is required until/unless i do a hydraulic steering conversion, and in CAD based modern car design it is not like I can just pop a big unit like that somewhere else (plus the loom would be too short anywhere else too). So, the passenger side is OK to clear out (just use a smaller washer reservoir, potentially elsewhere), but the DS no beuno

      Well, all the best with the new camry It was interesting to hear about the UK process, it is generally a lot more streamlined here with a shipping agent looking after all the import side (noting the exact final price can still be a surprise.....) and I've used a few different brokers on the japan (or US) side, and never had any trouble with any of them....luck of the draw I guess. You mentioned you didn't get the auction sheet (understandable since you bought it from a dealer, not auction), but I always try and get hold of that because they are pretty thorough. I've imported 2x R grade vehicles over the years and both were fine, repairs in Japan are pretty thorough compared to here in Oz.

      BTW I measured the jack I have, it is 70mm at the saddle but you only have about 700 until it returns to 150mm high at the cylinder so it is good but no magic bullet.

      My experience with Rising Sun Exports Before agreeing to the sale I tried to do as much research as I could (obviously), his Facebook reviews are 98% and he goes Live at least once or twice a week. I contacted 2 people in the UK who had used him for their imports, both had positive feedback. His explanation and talk through of the import process was thorough, answering any query no matter how stupid it was. It felt as soon as the money was sent, communication dropped off. I asked for shipping updates every 2 weeks or so, not wanting to pester him, he never had any updates. I wasn't informed the car had been dropped off at the port, I only found out by his Facebook story. I asked for the photos taken at the port, knowing he would need some for insurance purposes. I received a few 5 second clips and that's it. When asked again, he said his staff had them. Weeks later I asked again, he tells me he doesn't have any, but does have 50 photos from the original advert. I never received them. I eventually got the documents sent via WhatsApp after I mentioned the port was requesting them. I purchased a CarVX report, to find out the vehicle is a Grade R with recorded accident damage, first recorded in 2017 when it was first auctioned. He never told me the grade, then again I didn't ask. His response was "Grade R means nothing, it wasn't chassis damage". Still, I would have liked to have been informed about it. Jon prides himself on being open and honest when it comes to inspecting cars, it's his main job doing so at the auctions for customers. When the vehicle arrived in the UK I noticed a few little cosmetic issues. It's a 21 year old car so it wasn't going to be mint condition. The side skirts are cracked on each corner and the sealant is failing. The front grill on the bonnet/hood isn't secured very well, mounting studs are missing. Both minor things, but again, it would have been nice to be told. During a Facebook Live walk around video of the vehicle, he mentioned it has a front Whiteline anti roll bar/sway bar. While on the inspection ramp, I noticed the stock item has been installed. When first questioned, his response was "the ARB? Switched? Since when, it never had them". Since sending video and photo evidence I've not received a response. I'm probably being over critical of the overall condition of an old car, but all I wanted was honesty (which he claims to have). I'm aware I wasn't his only customer, he's busy doing XYZ but other reviews praise him for great communication with regular updates and photos, I felt I didn't receive the same treatment.
