Sludge88 Member 7 Member For: 17y 5m 2d Posted 05/03/08 12:02 AM Share Posted 05/03/08 12:02 AM Hi guys, just wondering if I could get some advice on boosting up my sound system. I have the standard Premo sound at the moment, but im looking to change out all 4 5"7"'s for better ones and add 2 12" subs to the boot. If I replace the standard amp can I plug it into existing wiring, or will I need one of these lineout converter units, and re-wire my whole car?Also with amp choices, would you reccomend seperate units, 1 for subs and 1 for speakers... or would one big amp do the whole job better?Any advice would be great Link to comment Share on other sites More sharing options...

Sludge88 Member 7 Member For: 17y 5m 2d Posted 06/03/08 01:21 AM Author Share Posted 06/03/08 01:21 AM Hey thanks for the reply So far ive managed to source 4 jbl 5"7"'s at 75 RMS speakers, and im looking at 2 12" jbl 300 RMS subs which im planning to build a custom box for under the parcel shelf in the boot, following some great posts ive found on in this forum.Alot of people on here have also said they had trouble getting a decent signal from the ICC to the amp, so I was wondering if I could use the existing signal hooked up to the stock Premo amp when I replace it... or I need to invest in a lineout converter?Amp choices.... No idea lol, is it better to slightly underpower or overpower with the RMS rating? any suggestions for make or model (keeping in mind im not made of money lol)Cheers Link to comment Share on other sites More sharing options...

I am looking at 3 JL10w3"s in the sides of the boot as thex each will go in a .5ft cub box. That way I keep as much of the boot space and can use the split fold seats Link to comment Share on other sites More sharing options...

And what kind of line out converter did you use? Link to comment Share on other sites More sharing options...

I wired it all in, in a few hours, (however I had done it all before in my previous ba). all up whole setup would be lucky to owe me $1800 but you could do it much cheaper with cheaper components.

WOW - serious stuff guys... have done a lot of that sort of thing in the past... But the best piece of advice I can give in reference to subs is this - MAKE SURE YOU INSTALL THEM CORRECTLY. ie- amp matching, and even more importantly BOX CONSTRUCTION AND 'TUNING'. something far to many people, including the typical local trasfield store does is, NOT 'tune' the sub box... Massive NO NO... I had a Honda Civic many years ago, and tuned a 10" single voice coil JL 10w04 in an over sized 40lt box, twin ports and ran some environment simulations via some special audio programs I have, and well everyone from the boys at trashfield, Ryda, JB HIFI, and the more specialist stores up here in Sydney never believe it was a single 10" until they looked in the boot!They all thought I had 2x 10" or in some cases 2x 12"Never less to say I ended up selling a few the plans and I believe there is a lot of cars floating around with the same sub and boxes now!!! If you want punch gets 10", 12" is a good all round size and over are just exactly that - OVER KILL!Good point from three monkeys on the oversize amp with lower gain - this will be one of the better things you can do - not much better ideas then clean power!!!
