Hi mate, Long time since I been on here lol... The fact the 'thumping' isn't present till you connect the RCA leads indicates the issue is before the amp.. Try removing the RCA leads from the Head Unit but connected to the amp, if the sub thumps the RCA leads are faulty... If the sub...

I can see no real issues with your wiring so far mate, the only change I would make is swapping the self tapping screw holding the amp earth for a nut washer & bolt.... The earthing of the alt & batt look fine, if there were any issue with regards ground loops system noise would be evident...

Possible causes of continued dimming; 1, New Batt/Chassis earth site --- Is it cleaned back to bare metal ??? 2, Amplifier Earth Site --- Ensure it is also cleaned back to bare metal & in a good location.... 3, Charge Circuit Inadequate --- Battery not big enough to cover extra load ...

Power Cap Power Cable The 'BIG THREE' 1, Battery -- Upgrade to Larger Capacity 2, Alternator -- Upgrade to Higher Output 3, Charge Circuit Wiring -- Upgrade all Charge Circuit wiring 'Kiddies Big Three' or number 3 'Charge Circuit Wiring' 1, Battery to Chassis Earth -- Upgrade or 'ADD TO'...

In simple terms; Larger cable cross sectional areas have lower resistance.... Shorter cable runs also have lower resistance.... So, longer cable runs require higher cross sectional area to keep resistance to a minimum.... So, shorter cable runs require lower cross sectional area to keep...

CAUTION; When working on a system you should pay heed to a few safety tips to avoid possible system damage; If any part of the boot power supply is to be disconnected, (Earth or Live), then always follow these easy steps to avoid possible head unit damage)..... 1, With system switched...

Background noise/Alternator whine.... To sort this you need to actually locate the source of the noise.... Is the noise only present with the engine running.... YES---Then its going to be a ground loop scenario, in 90% of cases its poor amplifier earthing thats the root cause...

If its a blown 'Earth Track', (common Pioneer issue), the interference will be present at all times whether the engine is running or not.... Alternator Whine can be caused by a number of issues, search for threads started by me, I think I covered it a while back... EDIT; Searched myself...

Found it... When starting the car always depress the clutch pedal, this reduces the load on the starting circuit.... Cable sizes; Batt to Fused Distribution Block--- 0awg Fused Distribution Block to Starter Motor--- 4awg minimum Alternator to Fused Distribution Block--- 4awg minimum...

Some interesting reading in this post.... When dealing with electrics there are usually 2 ways to do it, the adequate/safe route, or the performance route.... The current, (pun intended lol), electrical loom is designed with cost over safety in mind....So can be labelled as adequate.... I did...

That particular retailer is amongst the best with regards customer service, I would suggest you contact them by phone & have a word, by experience they won't sell it you if it won't do the job.....

If the amp shows a red protect light with the remote feed disconnected, (as stated in previous post), then its an amplifier fault...Simples...

That Vectra door, (not mine, pic simply used for ref), was covered using 'Second Skin' Damplifier Pro Matting then covered with 'Second Skin' Sludge.... It is all relative, some folks will spend £100+ deadening a door, some won't spend £100 deadening a full car.... The OP simply requires a...

Round & round we go.... A little common sense should be used to discern whether support is required or not.... In all cases any moving parts should be shielded from exposed adhesive backing, (obviously).... I usually use heavy polythene sheeting.... Using full length horizontal strips with a...

Depends on the size & shape of the hole being covered... In most cases simply covering the hole is fine, in some cases wire mesh can be used to add a little rigidity.... Where control rods pass through I use a piece of sponge, simply slice & slip over the rod where it passes through the...

For best results you need to effectively seal the door cavity.... There has been quite a few debates on whether any particular brand is better than most, in my opinion 'Dynamat Extreme' is excellent stuff.... BUT, when doing budget jobs where value for money is most important I always use...

Hi Mr Dink, You OK ?? Hope you had a good Christmas & a memorable New Year Party.... @ OP... With regards 'Sound Deadening' the front doors; The gaps or holes in the doors inner skin are there to allow access to the inner door components such as window regulators, glass guides etc etc...

OK, no need for dumbing down responses then.... So you've earthed your amplifier to a poor earth site.... Earth to a point on the chassis, select a point which allows the best return path to your battery.. Panel joins filled with caulking & welds will promote higher resistance.. Thats...

Firstly; The 'Big Three'.... 1, Alternator.... 2, Battery.... 3, Charge Circuit Wiring.... The 'Kiddies Big Three'.... 1, Battery to Chassis Earth.... You must add an earth that is at least equal in size to any new power cable.... 4awg power = adding 4awg battery earth.... 2, Alternator...

I'm after some footwear, got £100 quid to spend... Any advice or recommendations???? Pretty difficult to recommend anything without some relevant info isn't it mate.... Need to know; Space available for enclosure Type of music you mainly listen to Effect...

I would suggest you consider these retailers first mate; CAD CAS

As a guide; 16sq mm = 5awg = 60amps with approx 0.5v loss 20sq mm = 4awg = 80amps with approx 0.5v loss 50sq mm = 0awg = 200amps with approx 0.5v loss As the draw/load increases so does resistance.... As resistance increases voltage drops.... As distance between supply & load increases...

A fair few more than 150amps mate.... The 150amp fuse will not blow until it reaches around double its rated load.... The pic you linked to was based on a small engined Vauxhall, the best advice would be for you to check the stock battery specs for your car...Take note of the batteries CCA...

Any chance of a wiring diagram.... interested in how you eventually did it.... Just a short note; The purpose of using a relay is mainly to prevent the main draw being pulled via the switch. If you hard wire as mentioned above then the feed must travel from the battery to the switch, then...

Buying speakers with a higher power handling will yield no increase in output watt for watt.... To gain higher output watt for watt you would require a more sensitive speaker.... Higher power handling would equate to better quality, however, this usually leads to the speaker masking distortion...

Which model changer

Check power supply.... 1, Check for 12v on battery feed at amp....Use amp earth terminal then chassis earth as earthing for multi-meter.... 2, Check for 12v on remote feed at amp, (Head Unit ON)....Use earth sites as above.... If 12v indicated on all checks, then check any onboard fusing of the...

My 2 pence worth.... Dump the I-Poo.... Dump the Alpine Head Unit idea.... Dump the Pioneer Speakers idea.... Becker Head Unit mated with either Rainbow or DLS components up front with a Nice 10" sub in a sealed enclosure fitted in the boot, all driven by a nice Genesis amp....Well placed...

From your explanation of events & your description of why your cars handling was off, I too would be claiming from you.... You come across as a person who is unwilling to accept your choices actually caused & contributed to this accident.... If I were an attending Traffic Cop I would be...

If its normal, ask them to show you another....
